Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, funnel, and oil catch pan.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Check and Clear Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the "On" position without starting the engine.
Access the engine control module and read any stored fault codes.
Document the codes for further analysis.
Clear the codes and see if the check engine light returns after a test drive.

3. Inspect Engine Oil Level

Remove the dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the oil level.
If the oil level is low, add the appropriate type of oil as specified in the owner's manual.

4. Verify Oil Filter Installation

Inspect the oil filter for proper installation; ensure it is tight and not leaking.
If it appears loose or there are signs of oil leaks, tighten or replace the oil filter.

5. Check for Air Intake Problems

Inspect the air filter; if it’s dirty or clogged, replace it.
Ensure the intake hose is securely connected and free from any cracks or leaks.
