   • Use a socket set to remove any covers obstructing access to the timing chain/belt.
2. Inspect Timing Components:
   • Check for signs of wear or slack in the timing chain/belt.
   • Ensure that timing marks align according to manufacturer specifications.
3. Replace Timing Components if Necessary:
   • If worn, replace the timing chain/belt and tensioner according to specifications.

5. Clear Codes and Test Drive

1. Reconnect Battery:
   • Reconnect the battery terminals.
2. Clear Error Codes:
