Coolant temperature sensor, component description - GF07.04-P-6040MCC
ENGINE 132.9 in MODEL 451.3 /4
Location
The coolant temperature sensor is screwed onto the left side on the cylinder head.
Task
The coolant temperature sensor detects the coolant temperature and transmits a corresponding voltage signal to the ME-SFI [ME] control unit (N3/10).
Function
The NTC resistor integrated within the coolant temperature sensor changes its electrical resistance according to the coolant temperature. The ME-SFI [ME] control unit applies a sensor voltage of 5 V to pin 1 (1) and evaluates signal voltage at pin 2 (2) according to the coolant temperature.
