NOTE:
 Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general
troubleshooting information (see page 11-3).
 Because it requires 260 km (162 miles) of driving without refueling to complete this diagnosis, DTC
P0461 cannot be duplicated during this
troubleshooting.
1. Test the fuel gauge sending unit (see page 11-340).
Check for poor connections or loose
terminals at the fuel gauge sending unit and the
gauge control module (tach).
Replace the fuel gauge sending unit (see page
11-338), then go to step 2.
2. Turn the ignition switch to ON (II).
3. Reset the ECM/PCM with the HDS.
4. Do the ECM/PCM idle learn procedure (see page 11-310).
5. Check for Temporary DTCs or DTCs with the HDS.
Go to the indicated DTC’s troubleshooting.
Troubleshooting is complete. NOTE: Before you troubleshoot, record all freeze data
and any on-board snapshot, and review the general
troubleshooting information (see page 11-3).
1. Turn the ignition switch to ON (II).
2. Clear the DTC with the HDS, and wait 5 seconds.
3. Check for Temporary DTCs or DTCs with the HDS.
Go to step 4.
Intermittent failure, the system is OK at this
time. Check for poor connections or loose terminals
at the gauge control module (tach) and the fuel
gauge sending unit.
4. Turn the ignition switch to LOCK (0).
5. Remove the rear seat cushion (see page 20-131).
6. Remove the rear floor upper cross-member and the access panel from the floor (see page 11-334).
7. Disconnect the fuel tank unit 4P connector.
8. Turn the ignition switch to ON (II).
9. Clear the DTC with the HDS, and wait 5 seconds.
10. Check for Temporary DTCs or DTCs with the HDS.
Replace the fuel gauge sending unit
(see page 11-338), then go to step 22.
Go to step 11.
11. Turn the ignition switch to LOCK (0).
12. Remove the gauge control module (tach) (see page 22-277).
