水温传感器的功能是检测发动机冷却液温度,并将温度信号转换为电信号传送给发动机电控单元,电控单元根据该信号修正喷油时间和点火时间,使发动机工况处于最佳运行状态。当水温传感器发生故障时,发动机会易出现冷、热车启动困难、油耗增加、怠速稳定性降低、废气排放量升高等等故障现象。

The function of water temperature sensor is detected engine coolant temperature,and the temperature signal is converted to electrical signals transmitted to the engine electronic control unit,then the electronic control unit according to the signal for fuel injection time and ignition time, so engine condition runs at its best.When the water temperature sensor failure the engine is prone to starting difficulties in colding,increase in fuel consumption,reduced idling stability, emissions rising and so on
