Oil Temperature Sensor For ECM: Description and Operation
GF18.30-P-2010P Oil Temperature Sensor, Component Description
Location
The oil temperature sensor is located on the small oil pan at the middle front.
Task
The oil temperature sensor detects the current oil temperature and supplies a matching voltage signal to the CDI control unit (N3/9).
Design
The oil temperature sensor possesses an integral measuring resistor with a negative temperature coefficient (NTC).
Function
The NTC measuring resistor alters its electrical resistance in line with the oil temperature. Electrical resistance decreases as temperature increases.
Faults in the oil temperature sensor are detected by the CDI control unit and entered in the fault memory.
