Diagnostic Test

1) DTC IS ACTIVE
Start the engine and allow it to reach normal operating temperature.

WARNING: When the engine is operating, do not stand in direct line with the fan. Do not put your hands near the pulleys, belts, or fan. Do not wear loose clothing. Failure to follow these instructions can result in personal injury or death.

With the scan tool, select View DTCs.

Is the status Active for this DTC?

Yes
1. Go to 2).
No
1. Refer to the *CHECKING FOR AN INTERMITTENT CONDITION Diagnostic Procedure.
2) (N5) FUEL LEVEL SIGNAL 2 CIRCUIT SHORTED TO GROUND

Turn the ignition off.

Disconnect the Fuel Level Sensor connector.

Disconnect the Instrument Cluster (CCN) connector.

Measure the resistance between ground and the (N5) Fuel Level Signal 2 circuit in the Fuel Level Sensor harness connector.

Is the resistance above 100 ohms?

Yes
1. Go to 3).
No
1. Repair the (N5) Fuel Level Signal 2 circuit for a short to ground.
2. Perform PCM VERIFICATION TEST .
3) (N5) FUEL LEVEL SIGNAL 2 CIRCUIT OPEN CIRCUIT OR HIGH RESISTANCE

Measure the resistance of the (N5) Fuel Level Signal 2 circuit between the Fuel Level Sensor harness connector and the Instrument Cluster (CCN) harness connector.

Is the resistance below 5.0 ohms?

Yes
1. Go to 4).
No
1. Repair the (N5) Fuel Level Signal 2 circuit for an open circuit or high resistance.
2. Perform PCM VERIFICATION TEST .
4) FUEL LEVEL SENSOR
Turn the ignition off.

Connect the Instrument Cluster (CCN) connector.

Turn the ignition on.

With the scan tool, read the Fuel Level Sensor 2 signal voltage.

Is the voltage above 4.5 volts with the Fuel Level Sensor harness disconnected?

Yes
1. Replace the Fuel Level Sensor in accordance with the service information.
2. Perform PCM VERIFICATION TEST .
No
1. Go to 5).
5) INSTRUMENT CLUSTER (CCN)
Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Fuel Level Sensor and the Instrument Cluster (CCN).

Look for any chafed, pierced, pinched, or partially broken wires.

Look for broken, bent, pushed out or corroded terminals.

Monitor the scan tool data relative to this circuit and wiggle test the wiring and connectors.

Look for the data to change or for the DTC to reset during the wiggle test.

Refer to any Technical Service Bulletins that may apply.

Were any problems found?

Yes
1. Repair as necessary.
2. Perform PCM VERIFICATION TEST .
No
1. Replace and program the Instrument Cluster (CCN) in accordance with the Service Information.
2. Perform PCM VERIFICATION TEST .
