2004 Ford Explorer 4.0L Engine P0463 Fuel Level Sensor Fault Diagnosis
My 2004 Ford Explorer Limited with a 4.0L V6 gasoline engine is experiencing a fuel gauge issue where the gas needle moves further down beyond the empty mark when starting the vehicle. I have already replaced the fuel pump, but the problem persists. The check engine light has come on and displays fault code P0463, indicating a possible issue with the fuel level sensor or its wiring. I'm seeking advice on how to diagnose and fix this issue accurately. Any insights or troubleshooting steps would be greatly appreciated.
P0463 is typically caused by an open or shorted fuel level sensor wire. To resolve this, refer to the vehicle's wiring diagram and use a digital multimeter (DVOM) to test continuity and resistance in the sensor circuit.
