Code P0181 2003 Infiniti G35 Description

The P0181 code indicates a problem with the fuel temperature sensor circuit in a 2003 Infiniti G35. The fuel temperature sensor is responsible for monitoring the temperature of the fuel in the fuel tank. This information is crucial for the engine control module (ECM) to adjust the air-fuel mixture accordingly. When the ECM detects that the signal from the fuel temperature sensor is out of range or not performing within expected parameters, it triggers the P0181 code.
