For a complete Instrument Cluster Circuit Diagram, Schematics and Diagrams.

Diagnostic Test

1. MEASURE FUEL LEVEL SENSOR CIRCUIT VOLTAGE




Turn the ignition off.
Disconnect the Fuel Level Sensor harness connector.

NOTE: Check connectors - Clean/repair as necessary.

Turn the ignition on.
Measure the voltage between cavity 1 and cavity 2 of the Fuel Level Sensor harness connector.
Is the voltage approximately.7 of a volt?

Yes

- Replace the Fuel Level Sensor. Removal.
- Perform BODY VERIFICATION TEST. Body Verification Test

No

- Go to 2

2. MEASURE FUEL LEVEL SENSOR CIRCUIT RESISTANCE




Turn the ignition off.
Disconnect the Instrument Cluster C2 harness connector.

NOTE: Check connectors - Clean/repair as necessary.

Connect a jumper wire between cavity 1 and cavity 2 of the Fuel Level Sensor harness connector.
Measure the resistance of the Fuel Level Sensor circuit from cavity D4 to cavity D5 at the Instrument Cluster C2 harness connector.
Is the resistance below 5.0 ohms?

Yes

- Replace the Instrument Cluster.
- Perform BODY VERIFICATION TEST. Body Verification Test

No

- Repair the appropriate Fuel Level Sensor circuit for an open.
- Perform BODY VERIFICATION TEST. Body Verification Test
