P0460 - Fuel Level Sensor A Circuit

WARNING: This page does not describe the selected car, but rather 28 other vehicles, including the 2014 Lincoln Navigator, 2014 Lincoln MKZ, 2014 Lincoln MKX, 2014 Lincoln MKT, and 2014 Lincoln MKS. However, it is still accessible from the selected car via links, so may be relevant.
P0460 - FUEL LEVEL SENSOR A CIRCUIT

Description:  The PCM calculates the amount of fuel used during operation. This DTC sets when the FLI signal does not change or does not correspond with the calculated fuel usage. For vehicles with a dual container (saddle type) fuel tank, either fuel level sensor may set this DTC.
Possible Causes: 
  • Stuck float arm
  • Fuel level is always greater than 95% due to refueling patterns
  • Fuel level is always less than 5% due to refueling patterns
  • Fuel level is always at the same level between 3% and 97% full due to refueling patterns
  • Fuel pump (FP) module concern
  • Damaged instrument panel cluster (IPC)
Diagnostic Aids:  Check with the customer for driving and fueling habits that would keep the fuel level at approximately the same value. Monitor the FLI PIDs while attempting to move the fuel level float by adding or removing fuel as necessary.
