Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, oil filter wrench, and a clean rag.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical issues during work.

2. Inspect Oil Level and Condition

Locate the dipstick, remove it, and wipe it clean with a rag.
Reinsert the dipstick fully, then remove it again to check the oil level.
If the oil is overfilled, remove excess oil using a siphon pump.

3. Check Oil Filter Installation

Inspect the oil filter for proper seating.
If it's loose, tighten it by hand or with an oil filter wrench until snug.
If it appears damaged or defective, replace it with a new one.

4. Clear Error Codes

Use an OBD-II scanner to check for any stored error codes.
If codes are present, note them down, and clear them using the scanner.
Reconnect the negative battery terminal.

5. Test Drive

Start the engine and allow it to idle for a few minutes.
Take the vehicle for a short test drive to ensure the engine operates smoothly and the check engine light does not reappear.
