Special Tools Required

Fuel sender wrench 07XAA-001010A

1. Check the No. 9 BACK UP LIGHT INSTRUMENT LIGHT (10A) fuse in the driver's under-dash fuse/relay box before testing.
2. Turn the ignition switch OFF.
3. Remove the driver's side second row seat (see SECOND ROW SEAT REMOVAL/INSTALLATION ).
NOTE: Be careful not to cut the wire harness that is under the carpet.

4. Cut the carpet at the dotted line (see step 3 on Fuel Filter Replacement  ).
5. Remove the access panel (A) from the floor, then disconnect the fuel pump 5P connector (B).
6. Measure voltage between fuel pump 5P connector terminals No. 1 and No. 2 with the ignition switch ON (II). There should be battery voltage.
   • If the voltage is as specified, go to step 9.
   • If the voltage is not as specified, go to step 7.

7. Turn the ignition switch OFF. Check for continuity between fuel pump 5P connector terminals No. 1 and body ground. There should be continuity.
   • If there is continuity, go to step 8.
   • If there no continuity, check for poor ground (G505).

8. Measure voltage between gauge assembly connector B (22P) terminal No. 22 and body ground with the ignition switch ON (II). There should be battery voltage.
   • If the voltage is as specified, check for an open in the YEL/BLU wire.
   • If the voltage is not as specified, replace the gauge assembly.

9. Turn the ignition switch OFF. Remove the No. 13 BACK UP (7.5A) fuse from the passenger's underhood fuse/relay box for at least 10 seconds, then reinstall it.
10. Install a 2 Ω resistor between fuel pump 5P connector terminals No. 1 and No. 2, then turn the ignition switch ON (II).

NOTE: The pointer of the fuel gauge returns to the bottom of the gauge dial when the ignition switch is OFF, regardless of the fuel level.
11. Check that the pointer of the fuel gauge indicates "F".
    • If the pointer does not indicate "F", replace the gauge.
    • If the pointer indicates "F", inspect the fuel gauge sending unit, then go to step 12.
12. Relieve the fuel pressure (see Fuel Pressure Relieving  ).
13. Remove the fuel fill cap.
14. Disconnect the quick-connect fittings from the fuel pump.
15. Using the tool, loosen the fuel tank unit locknut (A).

NOTE: Remove the No. 13 BACK UP (7.5A) fuse from the passenger's under-hood fuse/relay box for at least 10 seconds after completing troubleshooting, otherwise it may take up to 20 minutes for the fuel gauge to indicate the correct fuel level.

16. Measure resistance between the No. 1 and No. 2 terminals with the float at E (EMPTY), 1/2 (HALF FULL), and F (FULL) positions. If you do not get the following readings, replace the fuel gauge sending unit (see step 10 on Fuel Pump Replacement  ).
