Fuel Temperature Sensor (A) Circuit Low

The fuel tank 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..

Cause:
Faulty Fuel Temperature Sensor
Fuel Temperature Sensor harness is open or shorted
Fuel Temperature Sensor circuit poor electrical connection

Symptoms:
Check engine light
