P0462 - Fuel Level Sensor A Circuit Low

WARNING: This page does not describe the selected car, but rather 32 other vehicles, including the 2008 Mercury Sable, 2008 Mercury Mountaineer, 2008 Mercury Milan, 2008 Mercury Mariner, and 2008 Mercury Grand Marquis. However, it is still accessible from the selected car via links, so may be relevant.
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
  • FLI circuit short to ground
Diagnostic Aids:  Monitor the FLI PIDs in key ON, engine running. A concern is present if the FLI percentage PID is at 25% fill and the FLI voltage PID is less than 0.90 volt with a non-matching fuel gauge or the FLI percentage PID is at 75% fill and the FLI voltage PID is greater than 2.45 volts with a non-matching fuel gauge.
