DTC P0463: Fuel Level Sensor 'A' Circuit High Input: General Description

The Fuel Level Sensor (FLS) measures the fuel level in the fuel tank; the fuel level information is used to supply the ECM/PCM with information regarding the monitoring condition of the EVAP canister purge system for leak detection. The FLS is monitored for High, Low, Stuck or Difference between consumed fuel level voltage and fuel level sensor voltage deviation exceeds the limited value while driving, this is interpreted by the ECM/PCM as a fault.
