Fuel temperature sensor component description

Location
The fuel temperature sensor (B602) is located on the flange for the fuel supply system of the fuel high-pressure pump.

B602

Fuel temperature sensor

W47.50-1020-06

Task

The engine management (MCM) control unit (A4) determines the fuel temperature over the fuel temperature sensor (B602).

Structure

There is an NTC resistor inside the fuel temperature sensor (B602). NTC stands for "Negative Temperature Coefficient", which means that electrical resistance falls as temperature rises.

Function

The fuel at the fuel temperature sensor (B602) influences the temperature measuring element inside the sensor depending on its temperature and thus the size of the electrical resistance. The engine management control unit (MCM) (A4) derives the associated temperature from the electrical resistance.
