P0181 - Fuel Temperature Sensor 'A' Circuit Range/Performance

Possible causes
- Faulty Fuel Temperature Sensor
- Fuel Temperature Sensor harness is open or shorted
- Fuel Temperature Sensor circuit poor electrical connection
What does this mean? What does this mean?
When is the code detected?
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.
Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
P0181 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..
