Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, oil filter wrench, and a multimeter if needed.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Retrieve Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the "ON" position (do not start the engine).
Follow the scanner's instructions to read and record any error codes.
Disconnect the scanner after noting the codes.

3. Check Oil Level and Quality

Remove the dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the oil level.
If the oil is low, add the correct type of oil gradually until the proper level is reached.
If the oil appears dirty or contains metal particles, consider a full oil change.

4. Inspect Oil Filter

Locate the oil filter and inspect for signs of leaks.
If the oil filter is loose or incorrectly fitted, tighten it to specifications (usually hand-tight plus 3/4 turn).
If necessary, replace the oil filter.

5. Verify Oil Type

Check the owner’s manual to confirm the recommended oil type (e.g., 0W-20 or 5W-20).
If incorrect oil was used, drain the oil and refill with the correct specification.

6. Reset the Check Engine Light

If the issue is resolved and no codes indicate a persistent issue, clear the error codes using the OBD-II scanner.
Turn the ignition off and then back on to ensure the light is reset.
