The Fuel Level Sensor(FLS) measures the fuel level in fuel tank and its information is used to supply the PCM with information regarding the monitoring condition of the EVAP canister purge system for leak detection. If the fuel level sensor is monitored for high or low stuck or difference between voltage of fuel level sensor and voltage deviation of fuel level sensor is exceeds limited value while driving, this is interpreted by the PCM as a fault.
PCM sets DTC P0463 if the PCM detects that the control line is short to battery or open.
