Fuel Temperature Sensor: Description and Operation
GF47.50-P-2010P Component Description For The Fuel Temperature Sensor
Location
The fuel temperature sensor is located on the right at the high-pressure pump.
Task
It detects the temperature of the fuel flowing in the high pressure pump and passes this information onto the CDI control unit (N3/9).
Design
The fuel 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 Coolant temperature. The electrical resistance decreases as the fuel
temperature rises.
