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.

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.

Removing the coolant sensor Lada Granta

The Lada Granta coolant temperature sensor is a thermistor (a resistor whose resistance changes depending on the temperature). The sensor is screwed into the thermostat housing and connected to the controller input, connected to an internal voltage source of 5 V through a 2 kOhm resistor. At low temperatures, the resistance of the sensor is high, and at high temperatures it is low (Table 1). The controller calculates the coolant temperature from the voltage drop on the sensor. On a cold engine the voltage drop is high, and on a warm engine it is low. Coolant temperature affects most of the characteristics controlled by the controller.

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.

How to find out what engine temperature is in a Lada Granta

The Lada Granta car is equipped with two instrument clusters. Let's call the first instrument cluster the old one; it does not have a temperature indicator, but only a warning lamp for engine overheating. Another model of the instrument cluster already shows the engine temperature, but only in the on-board computer.

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.

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.

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.

The Lada Granta car is equipped with two instrument clusters. Let's call the first instrument cluster the old one; it does not have a temperature indicator, but only a warning lamp for engine overheating. Another model of the instrument cluster already shows the engine temperature, but only in the on-board computer.

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.

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.

We found ways to save money. And putting an additional indication is a collective farm!

Where to buy a button?

Which button? If on-board instead of a button, then in almost any auto store that specializes in domestic cars!

You are probably talking about STATE1? So, my experience shows that STAT1 never shows the temperature accurately, sometimes the error ranges up to 13 degrees in the direction of underestimation!

Let us remind you that on the website you can find out what the real fuel consumption of the Lada Grant and Lada Kalina 2 should be.

I installed the additional indicator at a car dealership for 2500 rubles, purchasing it on June 9, 2014. Eh, I would have purchased the shipment after June 15, if only I had a computer on board)

I installed the indicator in the cabin for 2500 rubles on June 9, 2014, a necessary thing

Damn you are needed)) they write the red price is 600. ) And why are you lost) stop by and see the guys, they will stick you a flatbed for 35) I think they won’t refuse such a necessary person!)

Soon you will probably have to buy seats separately, like mats, armor. On the 14th, everything was there, engine temperature, ambient air temperature, battery charging. I bought a Lada Granta, there is nothing.

Solution from Maxim103

The car is September or August 2013, the equipment is the very first norm for casting (Izhevsk assembly), if the firmware costs 90, the sensor should be determined. How to check the firmware number: hold down the daily mileage reset button, turn on the ignition, all the lights on the panel should light up and the arrows should start moving up and down, release the mileage button, then press it again, the screen will display several lines with numbers, as far as I remember the version The top firmware looks like 090. Now, as far as I know, new firmware has been installed on all cars since the summer.

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.

Advantages of the E39 temperature sensor

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.

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.
