DTC Troubleshooting

Fuel Level Sensor (Fuel Gauge

Sending Unit) Range/Performance Problem

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 162 miles (260 km) of driving

without refueling to complete this diagnosis, this DTC
P0461 cannot be duplicated during this
troubleshooting.

1. Test the fuel gauge sending unit (see page 11-302).

Check for poor connections or loose

terminals at the fuel gauge sending unit and the
gauge control module.

Replace the fuel gauge sending unit (see page

11-300), then go to step 2.

2. Turn the ignition switch ON (II).

3. Reset the PCM with the HDS.

4. Do the PCM idle learn procedure (see page 11-273).

5. Check for Temporary DTCs or DTCs with the HDS.

If DTC P0461 is indicated, check for poor

connections or loose terminals at the fuel gauge
sending unit and the gauge control module, then
go to step 1. If any other Temporary DTCs or DTCs
are indicated, go to the indicated DTC’s
troubleshooting.

Troubleshooting is complete.
