Relevant Knowledge
The function of the water temperature sensor is to convert the cooling water temperature into an electrical signal, which is input into the ECU and has the following functions: 1. Correct the fuel injection quantity; Increase the fuel injection when the temperature is low. 2. Correct ignition advance angle; The ignition advance angle shall be increased at low temperature, and delayed at high temperature to prevent deflagration. 3. Affect the idle speed control valve; At low temperature, the ECU controls the action of the idle speed control valve according to the water temperature sensing signal to improve the speed.
Introduction to water temperature sensor: function
The temperature of the engine cooling water can then be obtained. The electronic control unit measures the temperature of engine cooling water according to this change. The lower the temperature, the greater the resistance. On the contrary, the resistance is smaller. 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.
Its interior is a semiconductor thermistor, the lower the temperature, the greater the resistance; On the contrary, the resistance is smaller. 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. The automobile water temperature sensor is installed on the water jacket of the engine cylinder or cylinder head, which is in direct contact with the antifreeze and is used to measure the temperature of the engine antifreeze. The temperature sensor used in the antifreeze thermometer is negative temperature coefficient (NTC). Its resistance decreases with the increase of temperature. The wire is connected to the electronic control unit (ECU). The other is ground wire.
Introduction to water temperature sensor: fault
1. Poor cold start
When the water temperature sensor fails, the electronic control unit is unable to obtain accurate water temperature signal and provide proper mixing ratio. If the mixture is too rich or too lean, cold start will be affected.
2. The idle speed is too high
The ECU checks that the water temperature signal is not accurate. It always thinks that the cold state affects the rich mixture of multi fuel injection, which will affect the high idle speed.
3. The fan always turns or does not turn.
The electronic control unit detects that the differential water temperature signal affects the normal rotation or non rotation of the fan.
4. The indication of water temperature gauge is abnormal.
The instrument detects that the water temperature signal is inaccurate, and the water temperature gauge displays abnormally.
