2. You can unplug the water temperature sensor, ground the plug wire, turn on the key, and see if the water thermometer on the instrument will move. If so, the water temperature sensor is broken. If it doesn't move, the instrument will be changed.
3. It is also possible that the power cord of the water temperature meter is broken, the electric heating coil of the water temperature meter is burnt out, the electric heating coil of the water temperature meter sensor is burnt out or poorly contacted, and the sensing wire of the water temperature meter is poorly connected or disconnected, so that the voltage stabilizer that provides stable power for the water temperature meter circuit will be damaged, resulting in the water temperature meter not moving.
