Two cables There are two cables between the water temperature sensor and the ecu, one is a voltage signal cable and the other is a ground cable.
3
Check the data of the water temperature sensor. Check the data of the water temperature sensor and compare it with the actual coolant temperature.
4
Whether there is a bad contact phenomenon so that it can be determined whether there is a bad contact phenomenon between the sensor and the control unit.
