Ford P0181 OBD-II Trouble Code Definition:

P0181 Fuel Temperature Sensor Circuit Range/Performance

P0181 Ford OBD-II Trouble CodeDescription:

OBD Trouble Code P0181
Fuel Temperature Sensor A Circuit Range/Performance
What does the code mean? OBD-ii Code P0181 definition:
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..
Symptoms Sumptoms of OBD code P0181
– Engine Light ON (or Service Engine Soon Warning Light)
Causes Causes of the OBD-II code P0181
– Harness or connectors (The sensor circuit is open or shorted) – Fuel tank temperature sensor may be faulty The Error code is generally activated on detection of the following conditions: Rationally incorrect voltage from the sensor is sent to ECM, compared with the voltage signals from engine coolant temperature sensor and intake air temperature sensor.
