DTC P0460: - FUEL LEVEL SENSOR A CIRCUIT

Description:	The powertrain control module (PCM) monitors the fuel level input (FLI) communications network message for a concern. The test fails when the PCM determines that the value of the FLI signal is stuck. The PCM calculates the amount of fuel used during operation. If the FLI signal does not change or does not correspond with the calculated fuel usage, the DTC is set.
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) (E-Series, MKS) Damaged instrument cluster (IC)
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.
