Fuel Temperature Sensor: Description and Operation
FTT SENSOR
Component Description
The fuel tank temperature sensor (3) is used to detect the fuel temperature inside the fuel tank. The sensor modifies a voltage signal from the ECM. The
modified signal returns to the ECM as the fuel temperature input. The sensor uses a thermistor which is sensitive to the change in temperature. The
electrical resistance of the thermistor decreases as temperature increases.

Fuel pressure regulator (2)
CAUTION: Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in damage to the ECM's transistor.
Use a ground other than ECM terminals, such as the ground.
