Ambient temperature sensor: position, device, circuit and features

Практически любой современный автомобиль is equipped with a large number of sensors. Some read the coolant temperature, others read the pressure in the lubrication system. We will talk about what the ambient temperature sensor is for, how it is installed and where it is located, depending on the brand of the car.

General information

As already noted above, various sensorscars are put not just. They are necessary for the effective operation of the system as a whole. As for the outdoor temperature controller, it is for the most part of an information character and shows the temperature overboard. But this does not apply to all systems. Sometimes the temperature sensor of the cooling medium is connected to the electronic engine systems. This is necessary to start the engine in the cold season and is a very convenient addition to the "autostart" function.

Unfortunately, not all cars havebuilt-in temperature sensor in the factory. In many models VAZ is not provided for. But it does not matter, we will consider how to install it and how remarkable this process is.

Where is the ambient temperature sensor located?

On different brands of cars, the controller hasdifferent arrangement. This is due in most cases to constructive differences between the machines. For example, on BMW it is possible to put the temperature gauge directly behind a bumper, and on VAZ - is not present.

Nevertheless, understand where the sensor is locatedtemperature of the environment is quite simple. We need to find his number in the electrical scheme, and that's it. In most cases, it is installed near the radiator, usually before or behind it. But it happens that it is mounted on the side. The main requirement is the absence of temperature influences from the motor side. The motor is heated and affects the controller. He, in turn, will give incorrect testimony.

"Lada Granta": mounting of the sensor

This car is equipped with a controller onlyin the maximum configuration. In other cases, there is preparation, that is, there are all necessary connectors and wires for connection. This is to ensure that the driver had the opportunity to perform the installation yourself.

Nevertheless, before mounting it is desirable to check,will the instrument panel display the controller's indication. To do this, press the button for the daily run and turn on the ignition. So we run a self-test, as a result, all the indicators are displayed. During the diagnostics, we repeatedly press the button of the daily run, which should cause the display version 090 or higher. This will indicate the possibility of installing a sensor

Direct installation

As noted above, the temperature sensorenvironment VAZ to establish uncomplicated. Especially if all connectors are provided by the manufacturer. The next step is the purchase of the sensor. There is nothing complicated, go to the car dealer and get the thing we need. The most optimal location of the sensor is near the radiator. Mass can be thrown on a welded pin. Wires need to be stretched to the salon. How it will be done depends on you. The most convenient and short way - through the clutch cap. Of course, without dismantling the dashboard can not do. We dismantle it and look for the 25th contact. It is designed for the temperature controller of the environment. Indications on the on-board computer usually appear automatically. If this does not happen, reset the battery connector for 10-15 minutes. After that, everything should work. The temperature sensor of the VAZ environment costs a penny. Its installation does not take much time.

How to install the ambient temperature sensor on the "Prior"

The standard equipment includes the presence of this controller. But there are cases when it is missing for some reason or another. For example, they took a used car, but there is no sensor or it is, but it does not work.

Впрочем, это не большая и проблема.However, to install or replace it will be necessary to remove the bumper, as it is not always possible to get up. It is located directly behind the front bumper and is mounted on the front of the body. If there is an air conditioner, then there will be two such sensors. First of all, it is necessary to check the efficiency of the old one. The best option is to take a household thermometer and compare the readings. Deviations may be caused by excessive voltage on the contacts.

Если датчик отсутствует, то устанавливаем его в corresponding socket. Wiring harness should be, so it remains only to connect and enjoy the result. If the old sensor jams, then take it out, turn on the ignition and check the voltage on the connecting block (wiring harness). It should be in the range of 3.5 V. If the voltage does not come, then the problem is somewhere in the circuit. We call and eliminate.

On installing the controller on the "Kalina"

Let's figure out how to install this carambient temperature sensor. "Kalina", unfortunately, often does not even have the necessary wires, so in the salon they have to pull yourself.

For installation, remove the bumper and installsensor, preferably in front of the radiator. There are only two wires - mass and signal. Mass we cling to the nearest bolt, for example from a beep. The signal wire is tied to the bundle by adhesive tape, although it is more preferable to use plastic clamps. In the salon to withdraw the most convenient through the plug, installed near the battery. We remove the device and connect the sensor. Usually the temperature shows immediately, even the terminals do not have to be thrown off. Now you know where the ambient temperature sensor is located on VAZ cars.

Finally

As you can see, there is nothing complicated in the connection.The most labor-intensive process is the removal and installation of the bumper. After that, you can be sure that you will not have to make any effort. Often the sensor is provided, but does not work. The reason can be not only in the controller, but also in the wiring, as well as bad contacts. Fortunately, all these nuances are eliminated using a multimeter and liquid VD-40.

It is recommended to put the original sensors, but notChinese analogues. The latter are bad because they can give incorrect testimony. Accordingly, there is no special meaning from such a device. The original usually serves for a long time and always works stably. There are, of course, cases when the controller burns out. The reason for this is the increased voltage on the sensor. Somewhere in the circuit, a short circuit is possible. Before installing a new device, it is recommended that you resolve any problems in the wiring.

That's figured out where the ambient temperature sensor is located, how it works and is installed. Everything is extremely simple. The main thing is to have a wish and a little free time.
