DTC P0462: Fuel Level Sensor A Circuit Low

P0462 - FUEL LEVEL SENSOR A CIRCUIT LOW

Description:  The powertrain control module (PCM) monitors the fuel level input (FLI) circuit for electrical failure. The test fails when the signal moves below 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
  • Damaged fuel gauge
  • FLI circuit short to ground
Diagnostic Aids:  Monitor the FLI and FLI V PIDs in key on, engine running (KOER). A concern is present if the FLI PID is at 25% fill and the FLI V PID is less than 0.90 volt with a non-matching fuel gauge or the FLI PID is at 75% fill and the FLI V PID is greater than 2.45 volts with a non-matching fuel gauge.
