Fuel Tank Temperature Sensor
The fuel tank temperature sensor (1) 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.
