- Ensure ignition switch is in OFF position. Remove fuel gauge sending unit access cover in luggage compartment. Disconnect connector from fuel gauge sending unit.
- Remove fuel gauge sending unit. Use an ohmmeter to measure resistance between fuel gauge sending unit terminals with sending unit float held at empty (down), half-full (middle) and full (up) positions. Compare readings with FUEL GAUGE SENDING UNIT RESISTANCE table. If resistance values are incorrect, replace fuel gauge sending unit.
