Is DTC P0335 indicated?

YES -

Check for poor connections or loose terminals at the CKP sensor and the PCM, then go to step 1.

NO -

Troubleshooting is complete. If any other Pending or Confirmed DTCs are indicated, go to the indicated DTC's troubleshooting.�

25. Reconnect all connectors.

26. Update the PCM if it does not have the latest software PCM Update, or substitute a known-good PCM.

27. Check for Pending or Confirmed DTCs with the HDS.

Is DTC P0335 indicated?

YES -

Check for poor connections or loose terminals at the CKP sensor and the PCM. If the PCM was updated, substitute a known-good PCM, then recheck. If the PCM was substituted, go to step 1.

NO -

If the PCM was updated, troubleshooting is complete. If the PCM was substituted, replace the original PCM Service and Repair. If any other Pending or Confirmed DTCs are indicated, go to the indicated DTC's troubleshooting.�
