Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for additional related fault codes that may provide more information. | OBD-II Scanner |
| Monitor the Sensor Signal for Intermittency | Use a diagnostic tool to monitor the sensor’s signal over time, checking for inconsistencies or erratic behavior. Compare the signal to manufacturer specifications. | Diagnostic Tool, Multimeter |
| Test the Sensor and Circuit | Test the sensor and its associated circuit for proper voltage and signal integrity, ensuring that there are no drops or erratic fluctuations. | Multimeter, Diagnostic Tool |
| Inspect Wiring and Connections | Inspect the wiring and connectors for signs of damage, corrosion, or loose connections that could cause an intermittent signal. Repair or replace as needed. | Flashlight, Multimeter |
| Clear the Code and Test Drive | After completing repairs, clear the fault code and take the vehicle for a test drive to verify that the issue has been resolved. | OBD-II Scanner |
| Recheck for Codes | Re-scan the vehicle after the test drive to ensure the P0C68 code has been cleared and does not return. | OBD-II Scanner |
