  1. Check the No. 10 METER (7.5 A) fuse in the under-dash fuse/relay box before testing.
  2. Check for body electrical system DTCs (see SELF-DIAGNOSTIC FUNCTION ).
  3. Turn the ignition switch to LOCK (0).
  4. Remove the second row seat (see SECOND ROW SEAT REMOVAL/INSTALLATION ).
  5. Pull the carpet back out of the way.
  6. Remove the access panel (A) from the floor.

  7. Disconnect the fuel tank unit 4P connector (B)
  8. Measure the voltage between fuel tank unit 4P connector terminals No. 1 and No. 3 with the ignition switch turned to ON (II). There should be battery voltage.
    • If the voltage is OK, go to step 9.
    • If the voltage is not as specified, check for:
      • a short in the LT BLU wire to ground.
      • an open in the LT BLU or LT GRN wire.

  9. Turn the ignition switch to LOCK (0).
  10. Remove the fuel tank unit from the fuel tank (see FUEL TANK UNIT REMOVAL AND INSTALLATION  ).
  11. Measure the resistance between fuel tank unit 4P connector terminals No. 1 and No. 3 with the float at E (EMPTY), LOW (LOW FUEL INDICATOR), 1/2 (HALF FULL), and F (FULL) positions.

    If you do not get the following readings, replace the fuel gauge sending unit (see FUEL PUMP/FUEL GAUGE SENDING UNIT REPLACEMENT  ).

    Float Position F 209.2 mm (8.2 in) 1/2 148.1 mm (5.8 in) LOW 42.8 mm (1.7 in) E 21.4 mm (0.8 in)
    Resistance (Ω) 19 to 21 200.9 to 210.9 566.4 to 685.2 772 to 788

  12. Reconnect the fuel tank unit 4P connector.
  13. Remove the No. 23 BACK UP (10 A) fuse from the under-hood fuse/relay box for at least 10 seconds, then reinstall it.
  14. Turn the ignition switch to ON (II).
  15. Check that the pointer of the fuel gauge indicates F with the float at F.
    • If the pointer of the fuel gauge does not indicate F, replace the gauge control module (see GAUGE CONTROL MODULE REPLACEMENT ).
    • If the gauge is OK, the test is complete.
    NOTE:
    • The pointer of the fuel gauge returns to the bottom of the gauge dial when the ignition switch is in ACC (I) and LOCK(0), regardless of the fuel level.
    • Remove the No. 23 BACK UP (10 A) fuse from the 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.
