Coolant Temperature Sensor/Switch (For Computer): Description and Operation



GF07.04-P-6040AMG Component Description For A Coolant Temperature Sensor







The temperature sensor is located at the front on the right cylinder head.

Function
The NTC resistor integrated in the temperature sensor alters its electrical resistance in line with the coolant temperature. The ME control unit (N3/10) analyzes voltage signal produced in line with the coolant temperature.







NTC means "Negative Temperature Coefficient", which means:The electrical resistance falls as the temperature rises (heat conductor).
