P0462 - FUEL LEVEL SENSOR A CIRCUIT LOW

Description:  The powertrain control module (PCM) monitors the fuel level input (FLI) communications network message for a concern. The test fails when the FLI signal is less than the minimum allowable calibrated parameter for a specified fuel fill percentage in the fuel tank.
Possible Causes: 
  • Empty fuel tank
  • Fuel pump (FP) module concern
  • Incorrectly installed fuel gauge
  • Damaged instrument cluster (IC)
  • Damaged fuel gauge
Diagnostic Aids:  Monitor the FLI parameter identification (PID) with the ignition on, engine running. A concern is present if the FLI PID is less than 25% fill with a non-matching fuel gauge or the FLI PID is greater than 75% fill with a non-matching fuel gauge.
