Diagnostic Trouble Code (DTC) Charts and Descriptions
P0460 - Fuel Level Sensor A Circuit (Continued)
All GO to Pinpoint Test HX.
P0461 - Fuel Level Sensor A Circuit Range/Performance
Description: This DTC sets when the FLI signal repeatedly moves in and out of range, exceeding the minimum or maximum
allowable calibrated parameters for a specified fuel fill percentage in the fuel tank. For vehicles with a dual container (saddle type) fuel tank, either fuel level sensor may set this DTC.
Possible Causes:
Diagnostic Aids: Verify aftermarket equipment does not generate radio frequency interference or electromagnetic interference
which may cause noisy FLI input signal.
Application Key On Engine Off Key On Engine Running Continuous Memory
All GO to Pinpoint Test HX.
P0462 - Fuel Level Sensor A Circuit Low
Description: This DTC sets 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
• Incorrectly installed fuel gauge
• Fuel pump (FP) module concern
• Damaged instrument panel cluster (IPC)
• Damaged fuel gauge
Diagnostic Aids: Monitor the FLI PIDs with the ignition ON, engine running. A concern is present if the FLI percentage PID is at
25% fill and the FLI voltage PIDs is less than 0.90 volt with a non-matching fuel gauge or the FLI percentage PIDs is at 75% fill and the FLI voltage PIDs is greater than 2.45 volts with a non-matching fuel gauge.

All GO to Pinpoint Test HX.
P0463 - Fuel Level Sensor A Circuit High
Description: This DTC sets when the FLI signal is greater than the maximum allowable calibrated parameter for a specified
fuel fill percentage in the fuel tank.
Possible Causes: • Overfilled fuel tank
• Fuel pump (FP) module concern
• Incorrectly installed fuel gauge
• Damaged instrument panel cluster (IPC)
• Damaged fuel gauge
Diagnostic Aids: Monitor the FLI PIDs in ignition 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.

All GO to Pinpoint Test HX.
P0480 - Fan 1 Control Circuit
For Relay Controlled Electric Cooling Fan
Description: This DTC sets when the PCM grounds the LFC circuit and excessive current draw is detected on the LFC
circuit; or with the LFC circuit not grounded by the PCM the voltage is not detected on the LFC circuit. The PCM expects to detect VPWR voltage coming through the low speed fan control (FC) relay coil to the LFC circuit.
Possible Causes: • LFC circuit open
• LFC circuit short
• VPWR circuit to the LFC relay open
• Damaged LFC relay
Diagnostic Aids: When the LFC_F PID reads YES, a concern is present. A short to voltage can only be detected when the PCM
is grounding the LFC circuit.
