Diagnosis Procedure

1. Turn ignition switch OFF.
2. Check combination meter and fuel level sensor unit and fuel pump (fuel level sensor) terminals (meter-side and harness-side) for poor connection.

Is the inspection result normal?

YES

GO TO 2

NO

Repair or replace terminals or connectors.

1. Disconnect combination meter harness connector M23 and fuel level sensor unit and fuel pump (fuel level sensor) harness connector B42.
2. Check continuity between combination meter harness connector M23 and fuel level sensor unit and fuel pump (fuel level sensor) harness connector B42.
