4. INSPECT FUEL RECEIVER GAUGE

(a) Disconnect the J5 fuel sender gauge connector.

(b) Check the fuel receiver gauge operation when the ignition switch is turned to the ON position.

No. 1 segment flashes.

(c) Connect terminals 2 and 3 on the wire harness side connector of the fuel sender gauge.

(d) Check the fuel receiver gauge operation when the ignition switch is turned from OFF to ON.

All segments, from No. 1 to No. 8, illuminate.

(e) Reconnect the fuel sender gauge connector.

5. INSPECT FUEL LEVEL WARNING LIGHT

(a) Turn the ignition switch to the ON position, and check that the receiver gauge No. 1 segment flashes when the fuel volume is less than 6.3 liters (less than 15 % of the total fuel tank capacity).

Fuel Volume

Flashing Speed (Interval)

1.6 gal (6.3 liters) (Less than 15 % of total fuel tank capacity)

Flashes slowly (1.2 seconds)

1.1 gal (4.2 liters) (Less than 10 % of total fuel tank capacity)

Flashes quickly (0.6 seconds)

6. INSPECT ENGINE OIL PRESSURE WARNING LIGHT
