Possible causes

– Faulty Engine Fuel Temperature Sensor
– Engine Fuel Temperature Sensor harness is open or shorted
– Engine Fuel Temperature Sensor circuit poor electrical connection

When is the code detected?

An excessively high or low voltage is sent to Engine Control Module (ECM).

Symptoms

– Engine Light ON (or Service Engine Soon Warning Light)

P0180 Description

The fuel tank temperature sensor is used to detect the fuel temperature inside the fuel tank. The sensor modifies a voltage signal from the Engine Control Module (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.
