Is Wuling lamp water temperature sensor and temperature control switch together?

Wuling lamp water temperature sensor and temperature control switch are not together.

The water temperature sensor sends a signal to the computer located on the cylinder.

The temperature control switch controls the fan to rotate at high and low speed, and the temperature control switch is on the water tank.

The function of the water temperature sensor is to convert the cooling water temperature into an electrical signal, which is input to the ECU:

1, the fuel injection quantity can be corrected. When the temperature is low, increase the fuel injection quantity.

2. The ignition advance angle can be corrected. Increase the ignition advance angle at low temperature and delay it at high temperature to prevent deflagration.

3. Affect the idle speed control valve. At low temperature, ECU controls the idle speed control valve according to the water temperature sensing signal to improve the speed.

2. Correct the ignition advance angle; Increase the ignition advance angle at low temperature and delay it at high temperature to prevent deflagration.

3, affect the idle speed control valve; At low temperature, ECU controls the idle speed control valve according to the water temperature sensing signal to improve the speed.

4. Affect the EGR valve.

Working principle of automobile water temperature sensor

Inside the automobile water temperature sensor is the automobile water temperature sensor. The lower the temperature, the greater the resistance. On the contrary, the smaller the resistance is, it is installed on the water jacket of engine cylinder block or cylinder head and directly contacts with cooling water. So as to obtain the temperature of engine cooling water.

According to this change, the electronic control unit measures the temperature of engine cooling water. The lower the temperature, the greater the resistance. On the contrary, the smaller the resistance. According to this change, the electronic control unit measures the temperature of engine cooling water as the correction number of fuel injection and ignition timing.

Simply put, you can know the current running state, whether it is stopped or moved, or how long it has been moving by the temperature of the engine water temperature.
