51. Remove PGM-FI main relay 2 (FUEL PUMP) (A)from the under-dash fuse/relay box.
52. Test PGM-FI main relay 2 (FUEL PUMP) (see page 22-70).
Go to step 53.
Replace PGM-FI main relay 2 (FUEL PUMP).
Also replace the No. 2 FUEL PUMP (15 A) fuse.
53. Check for continuity between PGM-FI main relay 2 (FUEL PUMP) 4P connector terminal No. 1 and
body ground.
Go to step 54.
Go to step 57. 54. Jump the SCS line with the HDS.
55. Disconnect ECM/PCM connector C (44P).
56. Check for continuity between ECM/PCM connector
terminal C36 and body ground.
Repair short in the wire between the No. 2
FUEL PUMP (15 A) fuse and the ECM/PCM (C36),
between the No. 2 FUEL PUMP (15 A) fuse and
PGM-FI main relay 2 (FUEL PUMP), or between the
No. 2 FUEL PUMP (15 A) fuse and the immobilizer
control unit. Also replace the No. 2 FUEL PUMP
(15 A) fuse.
Replace the No. 2 FUEL PUMP (15 A) fuse,
and update the ECM/PCM if it does not have the
latest software (see page 11-227), or substitute a
known-good ECM/PCM (see page 11-7), then
recheck. If the symptom/indication goes away with
a known-good ECM/PCM, replace the original ECM/
PCM (see page 11-228).
57. Remove the rear seat cushion (see page 20-131).
58. Remove the rear floor upper cross-member and the access panel from the floor (see page 11-334).

Sending Unit) Circuit Range/Performance
Problem Fuel Level Sensor (Fuel Gauge
Sending Unit) Circuit Low Voltage
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).
13. Disconnect the gauge control module (tach) 36P connector.

29. Reconnect all connectors.
30. Install the parts in the reverse order of removal.
31. Update the ECM/PCM if it does not have the latest software (see page 11-227), or substitute a known-
good ECM/PCM (see page 11-7).
32. Check for Temporary DTCs or DTCs with the HDS.
Check for poor connections or loose
terminals at the gauge control module (tach) and
the fuel gauge sending unit. If the ECM/PCM was
updated, substitute a known-good ECM/PCM
(see page 11-7), then recheck. If the ECM/PCM was
substituted, go to step 1.
If the ECM/PCM was updated, troubleshooting
is complete. If the ECM/PCM was substituted,
replace the original ECM/PCM (see page 11-228). If
any other Temporary DTCs or DTCs are indicated,
go to the indicated DTC’s troubleshooting. 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.
