P0181 INFINITI – Fuel Temperature Sensor Circuit Range/Performance

P0181 INFINITI Possible Symptoms

Engine Light ON (or Service Engine Soon Warning Light)

P0181 INFINITI Possible Causes

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

P0181 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 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..
