Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical issues while working.

2. Inspect and Tighten Components

Oil Drain Plug:
- Recheck the torque of the oil drain plug (typically 20-30 lb-ft).
- If leaking, replace the crush washer and retighten.
Oil Filter:
- Check if the oil filter is correctly seated and not leaking.
- If there's a leak, remove the filter, clean the mounting surface, and replace it with a new filter, ensuring the rubber O-ring is lubricated and seated properly.

3. Clear Error Codes

Reconnect the negative battery terminal after completing inspections.
Use the OBD-II scanner to clear any error codes related to the check engine light.
Start the engine and allow it to idle for a few minutes.

4. Test Engine Performance

Conduct a test drive to monitor engine performance and check if the check engine light remains off.
Pay attention to any unusual noises or performance issues.
