P0183 Subaru - Fuel Temperature Sensor 'A' Circuit High Input
' Add Comment
- Faulty Fuel Temperature Sensor
- Fuel Temperature Sensor harness is open or shorted
- Fuel Temperature Sensor circuit poor electrical connection
What does this mean?
When is the code detected?
An excessively high voltage from the sensor is sent to ECM.
- Engine Light ON (or Service Engine Soon Warning Light)
P0183 Subaru 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 increase
this sensor is in the fuel tank on the fuel pump assembly. If you look under the carpet behind the rear passenger seat, you should see a sort of rectangular access cover. Underneath this cover is the connector to the fuel pump. Make sure that all looks good. Could just be a bad connection. Sometimes when you have the fuel filter replaced a place will unhook this connector. When it's reconnected it might not be fully seated or have a bent pin or something

Testimonial: "Hey rebel thank you for the tip! I will definitely check on that asap. It sure would be nice not to have to replace it...seems almost pointless though as it apparently has little to no function in the driveability of the car. Well, at least it will pass the emissions test and maybe gain me some mileage along the way. Thanks again!!"
