Test D: Incorrect Fuel Gauge Indication (Gasoline & Alternative Fuel Mode)

WARNING: This page is about a different car, the 2002 Ford Pickup, 2001 Ford Pickup, and 2000 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: After making any repairs, clear DTCs and retest system.

Verify fuel gauge operation in both gasoline and alternative fuel modes. If fuel gauge operates correctly in both fuel modes, system is operating properly at this time and no further testing is needed. If fuel gauge does not operate correctly in gasoline mode only, go to TEST C: INCORRECT FUEL GAUGE INDICATION (GASOLINE MODE) . If fuel gauge does not operate correctly in alternative fuel mode only, go to TEST B: INCORRECT FUEL GAUGE INDICATION (ALTERNATIVE FUEL MODE) . If fuel gauge does not operate correctly in both modes, go to next step.
Disconnect both instrument cluster harness connectors. Inspect for pushed out terminals and corrosion. Reconnect instrument cluster harness connectors, ensuring they are connected correctly. Operate system and verify if concern still exists. If concern still exists, replace instrument cluster. See INSTRUMENT CLUSTER under REMOVAL & INSTALLATION. If concern does not exist, system is operating correctly at this time. Clear DTCs and repeat self-test.
