Outside temperature sensor VAZ 2170

On the display of the instrument cluster, whether it is a dashboard manufactured by Avtopribor, there is such a parameter as “ambient air temperature”. Many may think that the function is not particularly important, but in fact it is not. The outside temperature sensor performs its most useful function at the moment of the first frost. Having set out on the road during the day at above-zero temperatures, in the evening you can already get on ice on the street, of course, under certain circumstances. And it is by this sensor that you can be guided about possible problems with the road surface.

It is worth noting that if the threshold of this value approaches the minus mark, then the display will automatically first show the temperature, and not the current time, fuel consumption or other parameters.

On the display of the instrument cluster, whether it is a dashboard manufactured by Avtopribor, there is such a parameter as “ambient air temperature”.
Many may think that the function is not particularly important, but in fact it is not. The outside temperature sensor performs its most useful function at the moment of the first frost.

It is worth noting that if the threshold of this value approaches the minus mark, then the display will automatically first show the temperature, and not the current time, fuel consumption or other parameters.

Does fuel consumption increase with air conditioning?

In order to drive air inside the device, cool it and release it outside, you need to take energy. What contributes to energy production? Of course the engine is running. The harder it works, the more devices can receive stable “recharge”, and, accordingly, the higher the engine consumption becomes.

Initially, Lada is not ready for the air conditioner to operate, so it has to use additional resources in the form of fuel. Consumption from 100 km increases by 1 liter. By the way, to be fair, we note that the dynamics of the car do not decrease.

Replacing the air temperature sensor on a Priora

You can change the sensor yourself without any problems and will require a minimum of tools. But for greater convenience, you can remove the front bumper, although you can get by with less labor. So, we figured out where the street temperature sensor 2170 is located, now about the rest of the details.

Next, you need to remove the sensor from its seat in the radiator frame, applying a little force, since it sits on peculiar latches. Then you need to disconnect the block with the power wires from the air sensor. To do this, press the latch, as shown in the photo below:

And by slightly pulling to the side, we remove the block, which is clearly visible in the photo below.

The result is something like this:

Initial diagnosis

Before taking more serious steps, it is necessary to conduct a preliminary diagnosis.

Take the following steps:

Check the coolant level in the expansion tank. The coolant level should be between the minimum and maximum marks. If antifreeze constantly leaks, check the system for leaks. Inspect the pipes and tighten the clamps. Make sure that the oil level in the engine crankcase has not increased due to antifreeze entering through the cylinder block gasket.
Start the engine and wait until it reaches the optimal temperature.
Feel the thermostat. Look at the thick tubes that go from it to the car's radiator.
Make sure that after the engine warms up, the upper pipe heats up. If it is cold, then the cause is a broken thermostat. In this case, you cannot do without replacing the device. The second explanation for why the stove is not working correctly is a broken cap on the expansion tank. Install a new one and check again how the heating system works.
Check the cooling (heating) system for air. Let us immediately note that in a Priora, the appearance of an air lock is possible only when the antifreeze is depressurized or incorrectly filled. To fix the problem, warm up the car, turn the heater on to maximum, drive the front wheels up a small hill and periodically step on the gas. First remove the expansion tank cap. In this mode, let the engine run for 5-10 minutes.
Pay attention to the fan operation. If it does not move air well, remove the cabin filter and make sure it is not dirty. If you have such suspicions, replace the device.

Where to buy a new temperature sensor for Priora and the price of the part

Of course, little things like the sensor described in this article can be found without problems in almost any auto parts store. If you are unlucky and find it difficult to find a new part, then you can go to a dismantling shop, there is often enough of this goodness! As for the price, it may differ, but slightly, depending on the manufacturer and place of purchase:

VDO - 350 rub.
Kursk - 300 rub.
used - from 1000 rub.

Usually, if you notice problems with the readings or they do not agree with the real ones, that is: the environment is -10, and the display readings say -2 degrees, then there is clearly a problem that needs to be solved. Fortunately, on VAZ cars, and Priora is no exception - failure of such a sensor is extremely rare.

Connection

Procedure:

We insert one wire into the black block of the dashboard between the pink and black and white wires.
We connect the other wire to ground using a screw under the panel.

We check the presence of outside temperature readings on the display when switching modes. We perform assembly in reverse order. In the comments, leave the versions of your panels on which you managed to install a temperature sensor.

The installation of DTNV is also shown in the video:

Do you know how easy it is to change the interior of your car using vinyl film?

How to check the outside air temperature sensor on LADA

On all modern LADA cars, depending on the configuration, an external air temperature sensor can be installed, which transmits readings to the instrument panel. If the instrument cluster shows incorrect outside temperature values, then this sensor may be faulty. Before replacing, check it with a multimeter.

Where is the air temperature sensor located?:

on Lada Granta/Kalina/Priora in the lower cross member of the body (photo);
on Lada Vesta/XRAY in the lower left corner of the engine cooling radiator deflector (photo).

To remove it, in some cases it may be necessary to remove the front bumper and engine protection.

How to check the ambient temperature sensor ? The easiest way is to replace the sensor with a known good one. If you have an ohmmeter, you can measure the resistance at its terminals and compare it with the data from the table:

Installation

You will need : buy a temperature sensor (catalog number: 21150-3828210-00, 21150-3828210-02 or 21150-3828210-03, approximate price - 200 rubles), protective corrugation 3 meters and 3 meters of wires. Find out the model and firmware version of the instrument cluster, it should be 2190-3801010-20 (firmware 90 or 91) or 2192-3801010-20 (firmware 06 or 07). On other versions, the operation of the sensor is not guaranteed (it needs to be flashed).

Procedure:

We attach the outside air temperature sensor to its standard place behind the bumper, slightly above the towing eye (it is not necessary to remove the bumper).
We stretch the wires from it along the hydraulic corrector hoses, fastening the corrugation with the wires with plastic clamps.
From the engine compartment to the passenger compartment we pull the wiring through the hole in the engine panel. Inside, the wires will appear above the clutch pedal.

Temperature sensor outside Priora

We remove the outside air temperature sensor when replacing it. The sensor is installed on a bracket behind the front bumper. Disconnect the wire terminal from the negative terminal of the battery. Remove the front bumper (see “Removing the front bumper”). By pressing the pad lock...

...disconnect the wire block from the sensor. Squeezing the three sensor petals under the bracket...

...take it out of the bracket hole. Install the outside air temperature sensor in the reverse order.

Reasons for premature failure of DTOZH, DNTV

Third-party mechanical damage;
Manufacturing defect;
Crack on the base, body;
Circuit short circuit;
Loose terminals;
Moisture getting inside measuring instruments;
Burnout of the fuse melting element of the fuse box;
Incorrect operation of the system firmware of the ECU electronic control unit (error P1298, P5493).

Replacing the air temperature sensor on a Priora

The heater doesn't heat up at idle

Another problem that car owners face is problems with the kidney idling.

In this case, there are several reasons for the malfunction:

Low level of antifreeze in the cooling system.
Leaks that lead to the situation described in paragraph 1.
Airiness of the system.

The first two problems are rarely difficult to solve. The situation is different when the malfunction is caused by an air lock.

Take the following steps:

Remove the screen from the motor.
Loosen the clamp, then remove the throttle assembly heating tube and select any of the options.
Unscrew the cap of the expansion tank.
Place a clean rag on the neck and start blowing until coolant comes out of the removed pipe.
Place the tube onto the fitting and tighten the clamp.
Put the screen back in place.

If the considered method does not solve the problem, go through the following steps:

Warm up the engine to increase the pressure in the system.
Turn off the car and remove the tube from the throttle heating. In this case, there is no need to remove the plug from the cooling system tank.

Due to the high pressure, excess antifreeze will come out through the tube. Next, all that remains is to insert the tube into the fitting and tighten the clamp.

Blows constantly hot

Another situation that may arise when using the Priora stove is that it is not possible to regulate the temperature, and only hot air comes out of the system. Turning the regulator does not give any result.

In this case, do the following:

Measure the voltage at the control unit (see above).
Measure the voltage at the MMR (gear motor).
When switching to maximum and minimum voltage, 30 V of a certain polarity appears, and then drops to 0.
If the quiescent voltage is not 0, but is about 5 V, then the fault concerns the control unit.
In the case when the voltage is not normal and the damper does not change position, it is necessary to change the MMR.

Problem with outside temperature readings

Hello, comrades! The climate was changing. More precisely, one of the temperature sensors. Here's what we have: – the temperature in the climate hangs at one value. For example, in the morning it was +13, he showed me that much. But during the day it became +27, and in the climate it was still +13. – the temperature may suddenly change to the real one. But the morning one can hang all day. – due to incorrect temperature, the climate control does not work correctly and the air conditioner does not start. – vag-com does not show any errors.

How can I determine which temperature sensor is faulty? Surely two of them are at least responsible for the exterior? Is the readings freezing - is it a sensor glitch, or could the wiring be faulty?

Help, friends, the question is urgent. Thank you.

Typical breakdowns

The list of sensor failures is not very extensive, but if a malfunction does occur, it will most likely need to be replaced. If it doesn't work or doesn't work as expected, the following issues need to be addressed:

mismatch between temperature and resistance. In this case, there is a strong increase in resistance values when the outer part of the device is heated;
a break in the electrical circuit of the converter, due to which the electronics simply fail and does not turn on under any circumstances;
a rapid increase in voltage and resistance even with slight heating of the external part.

As a rule, all these reasons force car owners to buy and install new equipment. Next, we'll talk about where the sensor is located, as well as how to disconnect and reconnect it.
