DTC: P0183

Search Bulletins/Recalls for P0183

Trouble diagnosis name: Fuel tank temperature sensor circuit high input

Component 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..

DTC detecting condition:

• An excessively high voltage from the sensor is sent to ECM.

Possible cause:

• Harness or connectors (The sensor circuit is open or shorted)
• Fuel tank temperature sensor may be faulty
