Lada Granta temperature sensor: where is it located and how to replace it

03 March 2017 Lada.Online 73 804 6

The coolant temperature sensor (CTS) is one of the elements of the engine management system. Its purpose is to control the temperature of the fluid in the cooling system. Based on these data, the engine control unit adjusts the composition of the fuel-air mixture, crankshaft speed, and ignition timing.

On all modern LADA cars (XRAY, Vesta, Largus, Granta, Kalina, Priora or Niva 4x4), replacing and checking the coolant temperature sensor is carried out in the same way.

Old dashboard

This instrument panel was installed before June 15, 2014.

Find the engine temperature indicator here?

There is no engine temperature indicator on the old instrument panel. There is only an overheating warning light. On my previous cars, which did not have a temperature gauge, there were at least two warning lights: “cold engine” and “engine overheating”.

On the Grant, as planned by AvtoVAZ engineers, the engine should not be warmed up, and you can immediately start driving. Interesting savings. On our website there was a whole battle about this in the article: Is it necessary to warm up the engine before driving?

Car manufacturers allow the car engine not to warm up, citing global standards to prevent environmental pollution and save gasoline.

Read more about fuel consumption standards for the Lada Granta family of cars in the article: Grants fuel consumption on the passport and in reality, what is it like?

Ways to solve this problem

There are several ways to solve this problem. The simplest of them is to just hammer and drive like that. Most people do just that. You can flash the instrument panel, the result will be like this.

But in this car there is a hypothetical problem of the engine not heating up to operating temperatures, although AvtoVAZ management does not consider operating temperatures below 80 degrees a problem.

Installing a separate engine temperature indicator

The easiest and cheapest way is to install a separate temperature indicator instead of the standard free button plug.

Temperature gauge installed in place of the standard plug next to the cigarette lighter

Installing such a digital indicator will not take much time.

Make it a rule to always turn off the power to your vehicle when doing any electrical work!

1. You will need to remove the panel trim (if you don't have air conditioning, the ideal location would be to the side of the heated rear window button).
2. Next, disconnect the ground from the battery.

6. Carefully put everything back together in reverse order.

This indicator is sold in most car stores, the cost does not exceed 600 rubles.

Viewing the temperature using a smartphone (tablet)

This method will require you to purchase a diagnostic cable that works via bluetooth. You will also need an Android device that supports bluetooth connection.

1. Remove the diagnostic connector.
2. Connect the diagnostic cable there.
3. Install the “Torque” program or a similar one on your cell phone.
4. Launch the program on your phone, start the engine and try to establish communication with the adapter.
5. Once the connection is established, you can view the data that is transmitted from the sensors to the ECU.

New instrument panel

New instrument panel combination (from June 16, 2014)

If your car was manufactured after June 15, then the engine temperature should be displayed in the on-board computer. If it is not there, then you need to reflash the instrument panel.

How to Check Engine Coolant Temperature

How does the temperature sensor work on the Lada Granta? Where is he located? How to dismantle?

Lada Granta 2013, petrol engine 1.6 l., 87 l. p., front wheel drive, manual transmission - do it yourself

Participate in the discussion can only registered users.

What temperature sensors are installed on the Lada Granta, where are they located, price

In total, over ten digital and mechanical sensors are installed in the Lada Granta. The following deserve special attention and control from the driver:

• Coolant temperature sensor (hereinafter referred to as DTOZH);
• Environmental DT (hereinafter referred to as DTOS).

The functionality of the devices and the accuracy of data display depend on the condition of the technical equipment and the safety of driving a car.

Old dashboard

On vehicle models before 2014, it will not be possible to view the temperature on the dashboard in any case. And, if you pay attention only to the overheating light, then when it lights up, it may be too late to save the engine.

In this case, installing a special engine temperature indicator will help. However, you first need to understand what the on-board computer values ​​on the panel mean in order to understand the problem.

On-board computer values ​​on the panel

The manufacturer says that you can drive with an engine that is not warmed up. Although this is fraught with major overhauls not only for the engine, but also for the automatic transmission. If you warm up the engine, then in hot regions you may not understand when the engine warms up to 80 degrees, and the temperature jumps above the set point. And when the engine starts to boil, it will be too late to wave your hands.

So how do you know that the heating levels in the engine have reached their climax? In this case, experienced mechanics suggest installing a special engine temperature indicator.

Installing a separate engine temperature indicator

A similar engine temperature indicator is installed in any free hole in the car interior. The installation procedure itself does not take much time.

Attention! First you need to turn off all power in the car. It is best to remove the terminals from the battery.

Now you can begin the procedure:

1. Remove the panel trim.
2. Since the battery mass has already been disconnected, we proceed to the procedure for opening the glove compartment lid.
3. Find the diagnostic connector and pull it out.
4. Then a temperature indicator is placed in place of the plug and the wires are connected.
5. The other end of the wires is connected to the diagnostic connector and clamped.

Replacing the coolant temperature sensor on Grant

The coolant temperature sensor (not to be confused with the engine temperature indicator sensor) is installed on the Lada Granta car - directly on the thermostat housing.

It is this sensor that is responsible for the cold start of the car and prepares the mixture depending on the coolant temperature.

In other words, at a lower temperature of the coolant (in frost), one mixture is required, at a higher temperature, another.

If problems with starting are observed in different temperature ranges, it is necessary to check this particular sensor on the Grant. To do this you will need the following tool:

1. Phillips screwdriver
2. The head is 19 mm deep
3. Extension
4. Ratchet handle

Replacing the DVT on a Lada Granta car

To understand where this sensor is located, its location is clearly shown in the photo below.

So, the first thing you need to do is disconnect the power connector from the sensor itself, first bending the latch to the side, and the result of this action is shown in the photo below.

Next, you can begin to unscrew the sensor using a deep socket and an extension with a ratchet.

It is worth noting that for greater convenience it is necessary to move the inlet pipe to the side by unscrewing it from the mass air flow sensor.

After the old coolant temperature sensor is removed, you need to install a new one, first apply thread locker.

We install the new one in the reverse order. The price of the sensor is no more than 300 rubles for the original one produced by AvtoVAZ. Then we connect the chip into place and start the engine to check the functionality of the system.

Crankshaft position sensor

DPKV is responsible for providing the control system with information about the frequency with which the crankshaft rotates and its angular position. Based on this data, the ECU calculates the phase and duration of the pulses responsible for controlling the injectors and controlling the ignition coil. When reading information, the element sends the received data to the controller, whose task is to process it and issue the necessary pulses to the injectors.

The crankshaft position sensor is located near the oil filter.

The unit is highly reliable in operation and durable, and therefore its breakdowns occur infrequently. This is also due to the fact that the DPKV contains no mechanical moving parts.

The most common cause of its malfunction is corroded wiring. Failure of a part entails significant problems for the normal functioning of the engine; if repairs cannot be made, the unit will need to be replaced.

A breakdown of the crankshaft position sensor prevents the engine from starting. We list the main signs of its malfunction:

• problems starting the engine;
• unstable operation of the engine;
• loss of power, etc.

Grant engine temperature sensor. We install it ourselves

Every owner of a Lada Granta car has encountered its main drawback - the absence of an engine temperature sensor on the panel. The task of the AvtoVAZ management was to make Grant accessible, the engineers did it “excellently”, saving even on this device. The emphasis was on cheapness, so we tried.

Soon, however, everything was corrected - on models of a higher price and advanced configuration of the Lada Granta liftback 21911, 21912, 21917, an engine temperature sensor has already appeared and helps monitor the condition of the internal combustion engine.

However, what should owners of earlier models do? The overheating indicator lamp installed on cars is not informative enough.

In winter, it is impossible to determine whether the engine is warm enough to start driving, and in summer, the overheating warning light may come on too late.

The thermostat is the weak point of Lada Granta cars, and it would be much more effective to determine its malfunction at a very early stage by assessing the behavior of the TD sensor needle, but...

It was these problems that prompted some motorists to look for answers to the question: “How to install an engine temperature sensor on a Grant?” You can, of course, contact dealers. For a fee, specialists will equip everything you need. But there's no need to rush. It is not at all difficult to equip your car with this device yourself. To make sure of this, let's look at the whole process step by step.

First, you should purchase an installation kit for the coolant temperature sensor (engine). If you don’t want to go to a car store far, or don’t want to, you can easily order the necessary kit in an online store with home delivery. It includes:

1. temperature indicator,
2. plastic case for it,
3. the sensor itself;
4. fastening clamps.

Once you have the kit in your hands, it's time to head to the car. To see the place where the Grant engine temperature sensor will be attached, the negative terminal is removed from the car battery, and behind it the air filter is disconnected and removed.

This will open an overview of the pipe that leads from the thermostat. Coolant circulates through it during operation.

It is necessary to carefully cut the pipe and insert the temperature sensor inside along with the adapter (buy at a car store), then securely tighten it with clamps.

The wires are dealt with as follows: the first is the ground wire, it is attached to the engine (body), the second is pulled directly into the cabin.

An indicator with an arrow for the temperature sensor can be installed on the dashboard near the windshield next to the instrument panel. Visually this is very convenient, because... It is located close to eye level, and a quick glance will be enough to control the temperature level.

But what should you do if you may need to fix the navigator in approximately this place? The second option for mounting the sensor indicator is even more aesthetically pleasing.

Many motorists install the device in a cup holder next to the gearbox, but the panel itself will need to be slightly modified.

Of course, in this case you will have to look for a place for a glass of coffee, but this will be a huge plus: the sensor indicator in your cabin looks very harmonious. Now you can fully control the engine temperature and monitor how the thermostat behaves.

Speed ​​sensor

The DS is intended to measure the speed of a vehicle, with subsequent transmission of the received data to the ECU. The speed sensor is a small part; it is located in the upper part of the clutch housing, near the front wheel on the right. Its malfunction is usually directly related to a breakdown of the speedometer. However, the sensors installed on Grants are distinguished by fairly high quality and durability.

By the way, initially three types of speed sensors were installed on Grants: VAZ-2170 PEGAS, 2190 AVAR Russia and 21700-3843010-02.

More details about the speed sensor on Grants.

If the DS malfunctions, the electric power steering most often stops functioning, and at the same time the instrument panel begins to display error P-0501. As a rule, the steering wheel fails precisely because the car detects a breakdown of the speed sensor; the DS itself may show zero speed.

If the sensor fails, the following symptoms of failure are noted:

These parts have their own markings, their price ranges from 300 to 600 rubles.

Sensors on the Lada Granta engine

To ensure the normal operation of all vehicle components, modern cars use many different regulators. In this article we will talk in more detail about domestic Lada cars. Where is the speed sensor, coolant and other controllers on the Lada Granta and what functions do they perform - read below.

Sensor locations

Where is and how to find this or that regulator on Grant, Priora, Vesta or Largus? In fact, the location of the devices on these car models is identical. Below is a diagram identifying all devices.

Characteristics of sensors

Speeds

The Lada Granta speed sensor is located on the gearbox housing. This regulator is directly related to the transmission of data about how fast the vehicle is moving, how the car is idling, and what kind of gas mileage it is driving at.

To find this controller on a Priora or Grant, you need to open the hood and remove the air supply hose that goes from the air filter element to the throttle. Having done this, at the bottom of the gearbox housing you can see the controller with a wire connected to it. To replace the device, you simply need to disconnect the wiring and remove it from the installation location, and then replace it with a new one.

Removing DTOZH from a car

A coolant temperature sensor is necessary to measure the temperature of antifreeze in the cooling system. In accordance with the data from the temperature regulator on the Grant, the control unit adjusts the crankshaft speed, adjusts the composition of the combustible mixture, as well as the ignition timing.

As practice shows, such a device rarely fails, but in some cases it can give incorrect readings. Located in the engine compartment, in particular, in the thermostat cover, the controller has its own “diseases”. The wiring at the base of the connector may fray, resulting in the need to replace the DTOZH.

The mass air flow controller is located behind the air filter element of the power unit, it is also often called a flow meter.

The main purpose of the device is to monitor the volume of air flow that enters the vehicle engine.

In accordance with the data received, the on-board computer determines the required volume of gasoline, which is necessary to maintain a normal air-fuel ratio.

The idle speed sensor is one of the regulators designed to monitor and control the operation of the power unit. If the device breaks down, the motor immediately begins to work incorrectly - it will trip and the power will decrease.

In turn, the needle on the tachometer will jump sharply from one value to another. The element itself is located on the throttle, in particular on its lower part.

To get to it, you need to free the throttle valve from the pipes, there are four in total.

To replace and install a new IAC, you will need to disconnect the wiring from the regulator itself, as well as the throttle position controller.

Sveta

As for the light sensor, it is installed in the same housing with the rain regulator. Its purpose is to activate and deactivate lighting based on the current state.

For example, if it gets dark outside or you enter a garage or poorly lit tunnel, the device should automatically turn on the headlights along with the side lights.

The controller itself is not repairable, so if it fails, the only option is to replace it.

Clutches and brakes

The clutch sensor allows you to determine the position of the pedal. When the pedal is not depressed, the regulator turns off the load adjustment on the power unit. The device is located in the pedal assembly, in the same place where the brake sensor is located.

The operating principle of the latter is quite simple:

• when the pedal is released, the rod is located inside and clamps the floating contact to the top;
• when the pedal is depressed, the rod clamps the contact to the bottom of the group.

As practice shows, one of the main problems of this controller is the poor quality of the contact itself. It can simply catch on the spring, and ultimately the control unit will receive an impulse to apply the brake.

The vast majority of modern cars, including the Lada Granta, are equipped with digital sensors. “Scanners” transmit readings online to the electronic control unit of the ECU.

The on-board computer compares the received data with the programmed ones. In case of discrepancy, an error is indicated on the dashboard. The owner of the car, seeing a system error, decides on the nature of the breakdown and visits a service station to order a comprehensive diagnosis.

ATTENTION! A completely simple way to reduce fuel consumption has been found! Don't believe me? An auto mechanic with 15 years of experience also didn’t believe it until he tried it. And now he saves 35,000 rubles a year on gasoline! Read more"

What temperature sensors are installed on the Lada Granta, where are they located, price

In total, over ten digital and mechanical sensors are installed in the Lada Granta. The following deserve special attention and control from the driver:

• Coolant temperature sensor (hereinafter referred to as DTOZH);
• Environmental DT (hereinafter referred to as DTOS).

The functionality of the devices and the accuracy of data display depend on the condition of the technical equipment and the safety of driving a car.

DTOZH is designed to monitor the temperature of antifreeze in the cooling system circuit of the power unit. After receiving data about the “degree” of the engine, the ECU increases or decreases the speed of the power unit in order to adjust the temperature.

The quality composition of the fuel mixture depends on the accuracy of the DTOZ readings. The service life of the sensor is unlimited, with the exception of mechanical damage or manufacturing defects.

The standard installation location is the thermostat cover. The base part is screwed into the thermostat housing. Two power supply cables extend from the top.

A melting element is installed inside the DTOZh base. As soon as the antifreeze temperature reaches 90, the contacts close and the on-board computer signals an error.

Catalog articles, prices of temperature sensors for Lada Granta

Installed at the front bumper mounting location, to the left of the central air duct. The DTOS shape is conical with two contacts on the back side.

The fuse in the mounting block at number 32 is responsible for the operation of the DTOS. The first sign of a malfunction is the absence of temperature readings on the dashboard.

Why does coolant boil?

Sometimes you can see a car standing on the side of the road with the hood raised, from under which steam is pouring out. This is the result of a failure of the Lada Granta temperature sensor. The device provided incorrect information to the electronic control unit (ECU), and the ventilation system was unable to operate in time, which is why the antifreeze began to boil.

If the coolant temperature sensor (DTOZh) on the Lada Granta is faulty, the antifreeze may boil for several reasons:

1. Loose timing belt.
2. Destruction of the pump bearing.
3. Thermostat failure.
4. Antifreeze leak.

Loose timing belt

The belt tension may become weak due to the exhaustion of its running life or poor manufacturing quality. The belt begins to slide along the teeth of the pump drive gear. The speed of movement of antifreeze in the radiator drops, and the temperature sharply “flies” upward. The belt is tightened or replaced with a new product.

Timing belt:

Pump bearing failure

The consequence of a failure of the coolant pump bearing is that the pump begins to jam. Antifreeze stops moving inside the large cooling system circuit on the Grant, and the liquid, quickly heating up, reaches the boiling point of 100 ° C. The pump is urgently dismantled and replaced with a new pump.

Water pump:

Thermostat failure

Over time, the device may exhaust its resource, and the valve stops working when the antifreeze heats up. As a result, antifreeze cannot circulate in a large circuit and pass through the radiator. The liquid, remaining in the engine jacket, quickly heats up and boils. The thermostat needs urgent replacement.

Thermostat:

Antifreeze leak

This can happen due to leakage in the connections of the cooling system pipes, damage to the radiator, expansion tank and pump.

A low antifreeze level can be seen by the marks on the expansion tank. This will also be noticeable by how quickly the needle moves or the temperature values ​​​​change on the instrument panel interface.

You need to add fluid to the required level and go to the garage or service station.

Expansion tank:

Purpose

The process of ignition of the fuel mixture in the cylinders of the internal combustion engine is accompanied by an increase in temperature to 20000C. If you do not maintain operating temperature conditions, the cylinder block with all its parts will simply collapse. The purpose of the engine cooling system is precisely to maintain the thermal operating conditions of the engine at a safe level.

The Grant engine temperature sensor is a meter that tells the ECU about the degree of heating of the antifreeze. The electronic unit, in turn, analyzing data from all sensors, including DTOZH, brings all internal combustion engine systems to a balanced optimal operating mode.

DTOZH:

Design and principle of operation

The temperature meter on Grant is a thermal variable resistor. The thermocouple, enclosed in a bronze case with a threaded tip, reduces the resistance of the electrical circuit when heated. This allows the ECU to determine the coolant temperature.

DTOZH device:

If you look at the sensor in cross-section, you can see two contact petals located at the top and bottom of a thermistor made of a special metal alloy, which changes its resistance depending on the degree of heating.

It closes both contacts. One is supplied with power from the on-board network. The current, having passed through a resistor with a changed characteristic, exits through the second contact and enters the ECU microprocessor through the wire.

The following parameters of internal combustion engine operation depend on the DTOZH:

• temperature indicator readings on the instrument panel;
• timely activation of the internal combustion engine forced cooling fan;
• enrichment of the fuel mixture;
• engine idle speed.

Symptoms of a problem

All negative phenomena that arise as soon as the DTOZ fails can be described as follows:

• fuel consumption increases sharply;
• difficult starting the engine when cold;
• when starting, the muffler “smoke”;
• The radiator fan is constantly running;
• the fan does not turn on at a critical level of coolant temperature.

Before dismantling the meter, experts recommend first checking the reliability of the wiring and fastening of the connectors.

Where is

Finding a temperature meter is not at all difficult. The developers of the VAZ-1290, 91 Lada Granta model built a sensor into the thermostat housing.

This is exactly the place in the cooling system where you can record the maximum degree of heating of the antifreeze. If you lift the hood, you can almost immediately see where the thermostat is located.

It is located on the right side of the cylinder head. We find the sensor in the seat of the thermal valve body.

Location of the DTOZH (yellow nut visible):

Functionality check

To check the functionality of the controller, you need to remove it (see how to do this below) and prepare the following:

• sensor cleaned of dust and dirt;
• digital multimeter;
• thermocouple with sensor or thermometer;
• open container for boiling water.

Multimeter:

Check procedure

The DTOZH check is carried out as follows.

1. The dishes with water are placed on the stove and the gas burner is lit or the electric stove is turned on.
2. The multimeter is set to voltmeter mode. One probe makes contact with “0” of the meter. The second probe is connected to another terminal of the sensor.
3. The controller is lowered into the container so that only its tip is in the water.
4. During the process of heating water, changes in temperature and the value of the sensor resistance are recorded.

The data obtained is compared with the indicators in the following table:

Water temperature in the container, °C Sensor resistance, kOhm

If the readings differ from the tabulated data, this means that the coolant temperature sensor must be replaced, since such devices cannot be repaired. If the readings are correct, you need to look further for the causes of the malfunction.

Diagnostics with Opendiag mobile

The above method of checking the meter today can already be considered “old-fashioned”. In order not to bother with boiling water or specifically go to a service station to diagnose the electrical equipment of a Lada Granta, you only need to have an Android smartphone with the downloaded Opendiag mobile program and an ELM327 Bluetooth 1.5 diagnostic adapter.

ELM327 Bluetooth 1.5 adapter:

Diagnosis is carried out as follows.

1. The adapter is inserted into the diagnostic connector of the Lada Granta and the ignition is turned on.
2. In the phone settings, select Bluetooth mode. The name of the adapted device - OBDII - should appear on the display.
3. Enter the standard password - 1234.
4. Exit the Bluetooth menu and enter the Opendiag mobile program.
5. After the “Connect” command, error codes will appear on the screen.
6. If errors RO 116-118 are visible on the display, then the DTOZH itself is faulty.

Interface of the Opendiag mobile program on Android:

Replacement

If you have the skills to handle simple tools, then replacing a damaged device with a new sensor will not be difficult. Before starting work, you need to make sure that the engine is cold, the car is located on a level surface on the handbrake and with the negative terminal removed from the battery. After this proceed as follows:

1. Remove the contact chip with the cable from the head of the DTOZh connector.
2. Drain part (about ½ liter) of the coolant into a suitable container by unscrewing the bolt at the bottom of the engine block.
3. Use an open-end wrench to “19” to unscrew the old meter.
4. Install a new sensor and insert the contact chip into the DTOZH connector.
5. Antifreeze is added to the expansion tank to the required level.
6. The terminal is returned to its place on the battery.

Lada Granta displays temperature data on the instrument panel

As you know, AVTOVAZ removed the internal combustion engine temperature scale from the panel on the new Grants and Kalinas and left only the overheating light, but if it lights up, then this is already the beginning of the end.

Therefore, in luxury trim levels, the coolant temperature display was added to the on-board computer readings, and for all others, only a collective farm is assumed in the form of installing additional screens in place of button covers or external On-board computers.

To fix this problem, you can update the dashboard firmware of Lada Granta and Kalina 2 cars.

First, we find out what version of the firmware is embedded in the instrument panel.

For this:

1. With the ignition off, press the daily mileage reset button on the panel and, without releasing it, turn on the ignition, the service mode of the panel is activated, in which all the indicators light up and the arrows begin to move
2. release the button and press again. Numbers will appear on the display, this is the software version

Now let's decipher them

The first numbers (2190 or 2192) indicate the car model (Granta or Kalina 2). This is followed by the numbers 00, 20 or 40, which stand for “standard”, “norm” or “lux”, respectively.

Now, using the table below, you can see if it is possible to flash your panel so that it displays the temperature.

FIRMWARE VERSIONS OF INSTRUMENT PANELS LADA GRANT AND KALINA 2

1. Here is an example of firmware for the Grants Norma panel. Initially, the panel is sewn with firmware 090

2. We take out the panel, remove the back cover, and connect the programmer to a special connector on the panel board.

3. We upload the new firmware and go try it in the car. As you can see, the version has been updated and now firmware 092 is installed

4. And using the buttons on the right switch we switch the on-board computer readings and see that the temperature display has appeared.

Installing an outside temperature sensor on a Lada Granta

The outside air temperature sensor, despite its apparent simplicity and low usefulness, is actually quite an important element of driving safety. In spring or autumn, when the roads are often filled with melt water, driving a car at zero temperatures is especially dangerous.

From the driver's seat, the asphalt may appear dry or simply damp, when in fact the asphalt is coated with a glaze of ice.

The outside air temperature sensor will help predict these events, because if it shows the temperature below zero and the roads are wet, then most likely the asphalt will be extremely slippery and you will need to choose a different driving style and increase the distance to the car in front.

However, in order to save money, AvtoVAZ does not equip its cars with an outside temperature sensor in the basic configurations of the Lada Granta and Lada Kalina, but the ability to install it yourself is present in a number of cars.

To check the possibility of installing an outside temperature sensor on your car, you will need to check the firmware version of the instrument cluster.

To do this, with the car turned off, press the daily mileage reset button on the instrument panel and turn on the ignition. The instrument panel will go into self-diagnosis mode.

Press the odometer button again once and you will see the instrument cluster firmware version.

If your version is 090 and higher, then the instrument cluster is available for installing an outside temperature sensor. All versions that have a serial number below 090 do not provide for the installation of the corresponding sensor.

If in your case the instrument cluster is available for installing an outside temperature sensor, purchase the required sensor DVT-2115-3828210-03 from a car store.

The manufacturer provides a standard mounting location for the temperature sensor; it is located in the lower part of the engine cooling radiator on the frame of the bulkhead amplifier. The mass for the sensor is taken in the same place, there is a corresponding nut nearby.

The installation location is clearly visible with the front bumper removed. We marked in red the installation location of the outside air temperature sensor, and in black the installation location of the sensor mass.

We will need to run the power wire into the car interior and connect it to the instrument panel. You can insert the wire into any available rubber plug on the front panel, for example, into the clutch cable plug.

Having removed the instrument panel, we connect the positive wire to the 25th leg of the instrument panel connector. The installation location is marked with an arrow.

If the work is carried out correctly and according to our instructions, then when reassembling and connecting the instrument panel, the on-board computer menu item will contain a corresponding item displaying the temperature outside the car.

If the temperature indications do not appear, unscrew the negative terminal from the car battery for 5-10 minutes to reset the settings of the instrument panel and electronic control unit, after such a procedure the temperature indications should appear.

Camshaft position sensor (phase sensor) Lada Granta

This element is responsible for generating a signal, based on which the ECU is able to determine the angular position of the camshaft at any time period. On eight-valve AvtoVAZ engines, these devices are located at the cylinder head on the left, on sixteen-valve engines - in front and on the right of the engine.

If the phase sensor on the Grant breaks down, the system switches to operating in backup mode, which affects the stability of the engine. Repair of this sensor is impossible; any failure will require replacing the sensor with a new one.

The most common signs of DPRV failure include:

• unstable operation of the motor;
• problems starting the engine;
• the engine often stalls when the gas pedal is released;
• exceeding fuel consumption standards.

When diagnosing the device, the following errors are detected:

• P0340 – element is faulty;
• P0342 – low signal level;
• P0343 – the signal level supplied by the element is too high.

Replacing the coolant sensor Lada Priora

For the cooling system of any car, including the popular Lada Priora, it is not the most pleasant moment to be stuck in a traffic jam for a long time. When the car moves without long periods of downtime, the temperature load is removed by the oncoming air flow. There is no such flow when idling. When overheating, the radiator fan automatically turns on, but only if the coolant temperature sensor is working properly. This is a very necessary functional device for a car.

If the sensor does not work, replacement is required. In this material we will analyze in detail how the device works and where it is located. No less useful will be information on how to change this sensor on a Lada Priora. To replace, you will need a certain set of tools; such a tool is not a problem for a hundred; it is available in any car service center.

How the cooling system works on Priora

The system we are considering in the popular Lada Priora works by circulating fluid, as expected, through the radiator. The temperature decreases solely due to airflow. What types of blowing are there:

1. The look is natural. As the name implies, in this case the natural air flow cools the radiator while driving.
2. Kind of forced. When excessive heating occurs, the built-in fan is activated.

Grant temperature sensor: where is the DTOZH located on the Lada

First, it’s worth understanding why temperature meters are needed in a car. It is completely clear what internal and external air temperature meters do.

They carry out their measurements, transmit a signal to the car’s ECU, and thanks to their work, the car either carries out climate control, or regulates the operation of the car’s mechanisms, or simply displays the obtained measurements on the dashboard (however, this is often done bypassing the ECU altogether).

Why, for example, do you need a coolant temperature sensor (DTOZH)? His work, although it seems just as obvious, is actually deeper in nature.

So, before antifreeze enters the engine, it passes through a meter, which records its temperature and sends it to the main computer. These measurements serve as analytical data for the processor, giving it an understanding of the efficiency of the heatsink.

After all, the coolant travels a long way, through the engine to the radiator, and then, wobbling through its tubes, returns to the engine, where it is re-measured.

The radiator is designed in such a way that air flows counter to the car cool the antifreeze without unnecessary costs on the part of the car. However, in hot weather or standing in a traffic jam, this may not be enough, and then the computer decides to turn on additional cooling in the form of fans located inside.

At the same time, the Lada Granta DTOZH, with its measurements, helps the computer determine the need for additional fuel injection. Although more often devices that measure incoming air or outgoing air (exhaust) are responsible for this.

As a result, the main positive criteria for the work of the DTOZh include:

1. reduction in fuel consumption;
2. reducing wear on machine mechanisms;
3. improving vehicle performance and avoiding overheating.

This can also include bonuses such as notification to the driver or analysis of the operation of one or another form of coolant. But this already depends on the ability of the drivers themselves to recognize such signals.

How does the Grant temperature sensor work?

The coolant temperature detector in the Lada Granta is installed on the thermostat housing. To work with it, you will need standard tools like a Phillips screwdriver, two pairs of hands, and perhaps a 19 mm deep socket to simplify the work.

The dismantling of the meter in the Lada Granta itself takes place in several stages:

• we find where the device is located, remove the air filter that prevents us from getting to it;
• disconnect the wires from the meter;
• remove the connector from the detector;
• Let's start unscrewing the device.

Before dismantling, be sure to turn off the power to the car by removing the terminal from the battery. After this, be sure to drain the coolant. Failure to comply with any of these conditions poses a threat to your life and health.

Installation of a new device occurs in reverse of its dismantling. That is, they screwed it in, put the wires back in place, and put the air filter back. After that, we poured back the antifreeze and connected the electricity.

However, two installation nuances should be remembered. The first is to convince yourself of the quality of the seal of the new sensor or add your own sealant (coolant should not leak out while the car is running).

Well, the second comes out of the first - start the car and make sure there is no antifreeze leakage.

Bottom line

Repairing the Lada Granta DTOZ is easy and simple. At the same time, the benefits of the device are difficult to overestimate. Therefore, the logical conclusion is made that you should not neglect replacing a failed meter. Replacement should be done immediately.

The absence of a working DTOZh leads to the immediate activation of the additional cooling system, even if there is no need. As a conclusion, this leads to unjustifiably high fuel consumption during vehicle operation.

Temperature sensor T811 | Server room environment monitoring

Temperature sensors A (T811) are designed to measure indoor air temperature without the possibility of water entering the sensor housing. The sensors are made in the form of a board mounted on a plastic case with slots.

Thermal sensors (T811) are connected to NetPing 2 / PWR-220 v4 / SMS, NetPing 2 / PWR-220 v3 / ETH IP power distribution units (IP PDUs). Information on connecting temperature sensors (T811) is given in the “User Manual” documents of the corresponding NetPing IP PDUs to which they are connected. Information on setting up temperature sensors (T811) is given in the “Firmware Description” documents of the corresponding NetPing IP PDUs to which they are connected.

All server room temperature sensors are connected in parallel to each other to the same contacts. The sensor model is indicated on the body of each digital temperature sensor. Before using the air temperature sensor, you must set the temperature sensor address yourself. The temperature sensor address is set by removing the temperature sensor board from the case and installing mechanical switches (jumpers) in a certain place using a screwdriver included with the NetPing power distribution units, or manually:
