NOTE:
Since there is no direct method to test the inspection item, troubleshooting is performed using a known-good component.
Test Procedure
- Install a known-good CKP sensor and attempt to reproduce the failure.
Results
- If the failure is reproduced, there is a problem with other related components.
- If the symptom/DTC goes away, the CKP sensor must be faulty.
PCM Inspection
Test Procedure
- If the other inspection item(s) indicated a normal condition, then it is determined that the remaining PCM is the cause.
Results
- There is a problem with the PCM.
