În general vorbind, the water temperature sensor is installed on the engine cooling water channel, near the thermostat at the rear of the cylinder head. The price of the car water temperature sensor is not expensive, about a few dozen yuan, and the price of different channels will vary. For specific prices, you can consult YAXUN, YAXUN temperature sensor, especially the best customizable temperature sensor.

The function of the water temperature sensor is to convert the cooling water temperature into an electrical signal and input it into the electronic control unit:

1. Modify the fuel injection amount; increase the fuel injection at low temperature.

2. Correct the ignition advance angle; increase the ignition advance angle at low temperature, and delay the ignition advance angle at high temperature to prevent explosion.

3. Affect the idle control valve; when the temperature is low, the electronic control unit controls the action of the idle control valve according to the water temperature sensing signal to increase the speed.

The water temperature sensor is an NTC thermistor (negative temperature coefficient thermistor). Depending on the car manufacturers, it is usually installed next to the thermostat or inside it. Installed in the engine cylinder head water jacket, it is in direct contact with the cooling water, so as to measure the temperature of the engine cooling water. The water temperature sensor is also an electronic component in the automobile circuit. If it is broken, there is basically no room for repair, and it can only be replaced.
