  5. Is the measured resistance of Fuel Level Sensor within specifications?

    YES

    • Substitute with a known - good PCM and check for proper operation.
    • If the problem is corrected, replace PCM and go to "VERIFICATION OF VEHICLE REPAIR " procedure.

    NO

    • Substitute with a known - good Fuel Level Sensor and check for proper operation.
    • If the problem is corrected, replace Fuel Level Sensor and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
