Details of the Hyundai p0463 OBD Code
Hyundai fault code P0463 relates to fuel level sensor circuit high input.
OBD code P0463 for Hyundai vehicles indicates an issue with the fuel level sensor circuit.
This code is triggered by the Engine Control Module (ECM) when it detects a voltage signal from the fuel level sensor that is out of the expected range.
The fuel level sensor is responsible for sending the ECM information about the fuel level in the tank.
When the ECM receives a signal that is outside the normal operating parameters, it triggers the P0463 fault code.
This code is specifically related to the fuel level sensor circuit and can indicate problems with the sensor itself, the wiring, or the connections between the sensor and the ECM.
