Solution

1. Preparation

Gather tools and materials: OBD-II scanner, socket set, engine oil, oil filter, oil catch pan, and rags.
Park the vehicle on a level surface and engage the parking brake.

2. Check and Reset Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn on the ignition without starting the engine and read any stored error codes.
Note the codes for reference and clear them from the system using the scanner.
Start the engine and see if the check engine light reappears.

3. Inspect Engine Oil Level and Condition

Allow the engine to cool, then check the oil level using the dipstick.
If low, add the recommended oil type until it reaches the proper level.
If the oil appears dirty or contaminated, consider draining and replacing it.

4. Inspect and Replace Oil Filter

If the oil filter was not installed correctly or is defective, replace it with a new filter.
Use an oil filter wrench to remove the old filter and ensure the sealing ring comes off with it.
Apply a small amount of oil to the gasket of the new filter before installation.
Screw the new filter in place until snug, then tighten it an additional three-quarters of a turn.

5. Check for Leaks and Connections

Visually inspect the oil pan, oil filter, and surrounding areas for any signs of oil leaks.
Ensure that all wiring harnesses and hoses that may have been disturbed during the oil change are secure and undamaged.
