P0180 INFINITI – Fuel Temperature Sensor

P0180 INFINITI Possible Symptoms

Engine Light ON (or Service Engine Soon Warning Light)

P0180 INFINITI Possible Causes

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

P0180 INFINITI 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.
