Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, engine oil, oil filter wrench, shop towels.
Disconnect the negative battery terminal to reset the check engine light.
Allow the engine to cool for safety.

2. Check Oil Level and Quality

Remove the dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the oil level. Add oil if low.
Assess the oil quality; if it appears dirty or contaminated, consider changing it again.

3. Inspect Oil Filter

Use an oil filter wrench to remove the oil filter.
Check the O-ring on the old filter; ensure it is not stuck to the engine.
Install a new oil filter, ensuring it is tightened according to the manufacturer's specifications (typically hand-tight plus a quarter turn).

4. Verify Oil Type

Check the owner's manual for the correct oil specification (e.g., viscosity and API rating).
If the wrong oil was used, drain and replace it with the appropriate type.

5. Check for Vacuum Leaks

Visually inspect all vacuum hoses for damage or disconnections.
Reconnect any loose hoses and replace any damaged ones.

6. Clear Error Codes

Using the OBD-II scanner, clear the error codes after completing the checks and repairs.
Reconnect the negative battery terminal.
