Frontier XE 4WD L4-2.4L (KA24DE) (1998)
Fuel Temperature Sensor: Description and Operation
COMPONENT DESCRIPTION
The tank fuel temperature sensor 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.
