Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Check Oil Level and Condition

Use the dipstick to check the oil level.
If low, add the manufacturer-recommended oil type and viscosity.
If the oil appears dirty or has a burnt smell, consider an oil change.

3. Inspect Oil Filter

Use an oil filter wrench to remove the oil filter.
Check the rubber O-ring for damage and ensure the filter is properly seated.
Replace with a new filter if necessary.

4. Examine Engine Components

Inspect the air intake duct and hoses for any disconnections.
Look for any visible leaks around the engine or oil pan.

5. Reset Engine Light

After addressing any issues, use the OBD-II scanner to clear any error codes.
Disconnect the battery for a few minutes as an alternative method to reset the check engine light.
