1

Fuel gauge indicator light indication is incorrect

POSSIBLE CAUSE
•  Fuel gauge sender unit malfunction
•  Instrument cluster malfunction
•  Connector or pin malfunction
•  Fuel gauge sender unit is improperly installed
•  Open or short circuit in wiring harness between instrument cluster and fuel gauge sender unit
Note
•  The fuel gauge does not display the remaining fuel quantity correctly until the microcomputer built into instrument cluster calculates the fuel amount after refueling:

Diagnostic procedure

STEP

INSPECTION

ACTION

1
•  Switch the ignition to ON.
•  Verify that the fuel gauge needle does not move after engine switch is turned off, or the display does not indicate F even though fuel tank is full.
•  Is the fuel gauge normal?
Yes
Troubleshooting completed. (The system is normal.)
No
Go to the next step.
2
•  Retrieve the DTC of instrument cluster using M-MDS.
•  Is the DTC detected?
Yes
Go to applicable DTC troubleshooting procedure.
No
Go to the next step.
3
•  Inspect the instrument cluster.
•  Is the display normal?
Yes
Go to Step 7.
No
Go to the next step.
4
•  Switch the ignition to Off.
•  Inspect the instrument cluster connector terminals for poor connection (such as damaged/pulled-out pins, and corrosion).
•  Are the terminals normal?
Yes
Go to the next step.
No
Repair or replace the terminal.
5
•  Switch the ignition to Off.
•  Inspect for continuity following the wiring harness between instrument cluster and fuel gauge sender unit.
―  2T terminal—E terminal
―  2R terminal—A terminal
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace for open circuit in the wiring harness between the instrument cluster and the fuel gauge sender unit.
6
•  Switch the ignition to Off.
•  Remove the instrument cluster.
•  Disconnect the instrument cluster connector.
•  Inspect for continuity between the following wiring harness.
―  2R terminal—ground
•  Is there continuity?
Yes
Repair or replace the wiring harness for short to ground.
No
Replace the instrument cluster.
7
•  Switch the ignition to Off.
•  Inspect the fuel gauge sender unit connector terminals for poor connection (such as damaged/pulled-out pins, and corrosion).
•  Are the terminals normal?
Yes
Go to the next step.
No
Repair or replace the terminal.
8
•  Switch the ignition to Off.
•  Is the fuel gauge sender unit installed properly?
Yes
Inspect the fuel gauge sender unit.
No
Reinstall the fuel gauge sender unit.
