Code P0463 2000 Ford F150 Description

The P0463 diagnostic trouble code (DTC) for a 2000 Ford F150 indicates a Fuel Level Sensor A Circuit High. This code is typically triggered when the fuel level sensor in the vehicle's fuel tank detects a higher than normal voltage signal. The fuel level sensor is responsible for sending information to the vehicle's fuel gauge, allowing the driver to monitor the amount of fuel in the tank. When the sensor detects a high voltage signal, it indicates that the fuel level is higher than it actually is, leading to inaccurate readings on the fuel gauge.

Tech Notes for P0463 2000 Ford F150

The PCM monitors the fuel level input (FLI) circuit for electrical failure. The test fails when the signal moves above the maximum allowable calibrated parameter for a specified fuel fill percentage in the fuel tank.

When is the Code Detected?

An excessively high voltage is sent from the sensor is sent to Engine Control Module (ECM).
