The P0463 code in a 2005 Infiniti G35 indicates a problem with the fuel level sensor circuit, specifically a high input signal. The fuel level sensor is responsible for sending information to the vehicle's fuel gauge, informing the driver of the amount of fuel in the tank. When the sensor circuit detects a high input signal, it means that the fuel level sensor is reporting a fuel level that is higher than the actual amount of fuel in the tank.
Common Causes of P0463 2005 Infiniti G35
- Faulty fuel level sensor.
- Damaged wiring or connectors in the fuel level sensor circuit.
- Corrosion on the fuel level sensor contacts.
- Poor ground connection in the fuel level sensor circuit.
- Issues with the vehicle's PCM (Powertrain Control Module).
Symptoms of P0463 2005 Infiniti G35
- Inaccurate fuel level readings on the dashboard.
