Oil Temperature Sensor For ECM: Description and Operation
GF18.30-P-2010AMG Oil Temperature Sensor, Component Description
The oil temperature sensor is located at the front at the left side of the crankcase.
Function
The NTC resistor integrated in the oil temperature sensor alters its electrical resistance according to the oil temperature. The ME-SFI control unit
(N3/10) evaluates the corresponding voltage signal for the oil temperature.
NTC means "Negative Temperature Coefficient", which means:
The electrical resistance falls as the temperature rises (heat conductor).
