- Check the CKP NOISE count in the DATA LIST with the HDS.
Are 0 counts indicated?
YES -Go to step 7.
NO -Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the CKP sensor and the ECM/PCM.
- Check for poor or loose connections and terminals at these locations:

- ECM/PCM
- Engine ground
- Body ground
Are the connections and terminals OK?
YES -Go to step 8.
NO -Repair the connectors or terminals, then go to step 11.
