Cabin Compartment Node (CCN)
P2068-FUEL LEVEL SENSOR 2 CIRCUIT HIGH
For a complete wiring diagram, refer to the Wiring Information.
- When Monitored:
With the ignition on.
- Set Condition:
The Cluster detects that the Fuel Level Sensor input voltage is above the maximum acceptable value.
1. CHECK FOR AN ACTIVE DTC
1. Turn the ignition on.
2. With the scan tool, read DTCs.
Does the scan tool display this DTC as active?
Yes
- Go To 2
No
- Test complete, the condition or conditions that originally set this DTC are not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension.
2. (N5) FUEL LEVEL SIGNAL 2 CIRCUIT SHORTED TO VOLTAGE
1. Turn the ignition off.
2. Disconnect the Fuel Pump Module C2 harness connector.
3. Disconnect the Cluster C2 harness connector.
4. Turn the ignition on.
5. Measure the voltage of the (N5) Fuel Level Signal 2 circuit in the Fuel Pump Module C2 harness connector.
Is there any voltage present?
Yes
- Repair the (N5) Fuel Level Signal 2 circuit for a short to voltage.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
No
- Go To 3
3. FUEL PUMP MODULE
1. Turn the ignition off.
2. Reconnect the Cluster C2 harness connector.
3. Connect a jumper wire between the (N5) Fuel Level Signal 2 circuit and the (Z906) Ground in the Fuel Pump Module C2 harness connector.
4. Turn the ignition on.
5. With the scan tool, read DTCs
Does the scan tool display this DTC as active?
Yes
- Go To 4
No
- Replace the Fuel Pump Module.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
4. (N5) FUEL LEVEL SIGNAL 2 OPEN OR HIGH RESISTANCE
1. Turn the ignition off.
2. Disconnect the Cluster C2 harness connector.
3. Measure the resistance of the (N5) Fuel Level Signal 2 circuit between the Fuel Pump Module C2 harness connector and the Cluster harness connector.
Is the resistance above 5.0 Ohms?
Yes
- Repair the (N5) Fuel Level Signal 2 circuit for an open circuit or high resistance.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
No
- Go To 5
5. (Z906) GROUND CIRCUIT OPEN OR HIGH RESISTANCE
1. Measure the resistance between ground and the (Z906) Ground circuit in the Fuel Pump Module C2 harness connector.
Is the resistance above 5.0 Ohms?
Yes
- Repair the (Z906) Ground circuit for an open circuit or high resistance.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
No
- Replace the Cluster.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
