P0183: Fuel Temperature Sensor A Circuit High Input
Can you still drive? Yes, this is a low-severity code. The engine will operate with a default fuel temperature assumption.
What Does P0183 Mean?
Code P0183 means the fuel temperature sensor circuit is sending a voltage signal above the expected maximum to the ECM. This high voltage typically corresponds to an unrealistically low temperature reading, suggesting an open circuit or disconnected sensor rather than actual fuel conditions.
