DTC P0460:00

Fuel level sensor circuit malfunction
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 P0460:00 is set.
Diagnostic support note
• This is a continuous monitor (CCM).
• The MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.
• PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.
• FREEZE FRAME DATA (Mode 2)/Snapshot data is available.
• DTCs are stored in the PCM memory.
POSSIBLE CAUSE
• Instrument cluster malfunction
― Incorrectly installed fuel gauge
― Fuel level input signal circuit malfunction
• Amount of fuel is empty or overfilled
• Fuel gauge sender unit malfunction
• PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION
1
VERIFY FREEZE FRAME DATA (MODE 2)/SNAPSHOT DATA HAS BEEN RECORDED
• Has the FREEZE FRAME DATA (Mode 2)/snapshot data been recorded?
Yes
Go to the next step.
No
Record the FREEZE FRAME DATA (Mode 2)/snapshot data on repair order, then go to the next step.
2
VERIFY RELATED SERVICE INFORMATION AVAILABILITY
• Verify related Service Information availability.
• Is any related Service Information available?
Yes
Perform repair or diagnosis according to the available Service Information.
• If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3
VERIFY RELATED PENDING CODE AND STORED DTC
• Turn the ignition switch off, then to the ON position (engine off).
• Perform the DTC Reading Procedure and Pending Trouble Code Access Procedure. (See ON-BOARD DIAGNOSTIC TEST [L3 Turbo].)
• Are any other DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [L3 Turbo].)
No
Go to the next step.
4
VERIFY STORED DTC IN INSTRUMENT CLUSTER
• Turn the ignition switch off, then to the ON position (engine off).
• Perform the instrument cluster DTC inspection using the M-MDS. (See DTC INSPECTION [INSTRUMENT CLUSTER].)
• Are any DTCs present?
Yes
Go to the appropriate DTC inspection.
(See DTC TABLE [INSTRUMENT CLUSTER].)
No
Go to the next step.
5
INSPECT AMOUNT OF FUEL
• Visually inspect the amount of fuel.
• Is the amount of fuel normal?
Yes
Go to the next step.
No
Do the amount of the fuel to a proper level, then go to Step 7.
6
INSPECT FUEL GAUGE SENDER UNIT
• Turn the ignition switch off.
• Inspect the fuel gauge sender unit. (See FUEL GAUGE SENDER UNIT INSPECTION.)
• Is there any malfunction?
Yes
Replace the fuel gauge sender unit, then go to the next step.
(See FUEL GAUGE SENDER UNIT REMOVAL/INSTALLATION [L5, L3 Turbo].)
No
Go to the next step.
7
VERIFY DTC TROUBLESHOOTING COMPLETED
• Make sure to reconnect all disconnected connectors.
• Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE [L3 Turbo].)
• Perform the KOER self test. (See KOEO/KOER SELF TEST [L3 Turbo].)
• Is the PENDING CODE for this DTC present?
Yes
Replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION [L3 Turbo].)
No
Go to the next step.
8
VERIFY AFTER REPAIR PROCEDURE
• Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [L3 Turbo].)
• Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [L3 Turbo].)
