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 NISSAN 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.
