The Supply Fuel Temperature Sensor is located on the left side of the crankcase on the fuel filter module (1). The Motor Control Module (MCM) detects the current temperature of the fuel via the Supply Fuel Temperature Sensor. There is an NTC resistor inside the Supply Fuel Temperature Sensor. NTC stands for “Negative Temperature Coefficient” and means that the electrical resistance falls as the temperature increases. The Supply Fuel Temperature Sensor is a passive sensor (i.e., it is not supplied with voltage).
