id0102d2301400

DTC P0460:00 | Fuel level sensor circuit
--- | ---
DETECTION CONDITION | • The PCM monitors the fuel level input communications network message for a concern. The test fails when the PCM determines that the value of the fuel level input signal is stuck. The PCM calculates the amount of fuel used during operation. If the fuel level input signal does not change or does not correspond with the calculated fuel usage, the DTC is set.
POSSIBLE CAUSE | • Empty fuel tank • Fuel pump malfunction • Incorrectly installed fuel gauge • Instrument cluster malfunction • Fuel level input signal circuit malfunction • Overfilled fuel tank • Fuel gauge malfunction • Stuck float arm
