Code P0463 2016 Chevrolet Silverado Description

The P0463 diagnostic trouble code (DTC) for a 2016 Chevrolet Silverado indicates a problem with the fuel level sensor circuit registering a high voltage. The fuel level sensor is responsible for sending the fuel level information to the vehicle's engine control module (ECM) or powertrain control module (PCM). When the sensor detects a high voltage signal, it means that the fuel level in the tank is higher than what is actually present, leading to inaccurate readings on the fuel gauge.
