Solution

1. Preparation

Gather tools and parts: OBD-II scanner, socket set, oil filter wrench, new oil filter, engine oil, torque wrench.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery’s negative terminal to reset the engine light if needed.

2. Address Error Codes

Use the OBD-II scanner to read and record any error codes.
Clear the codes using the scanner, then reconnect the battery.

3. Confirm Oil Level and Quality

Check the oil dipstick to ensure the oil level is adequate; add oil if low.
If the oil appears dirty or contaminated, consider performing another oil change with the correct type of oil.

4. Inspect Oil Filter and Drain Plug

Use an oil filter wrench to remove the oil filter and check for proper installation and any leaks.
Tighten the oil drain plug to the manufacturer’s specified torque (typically around 30-40 ft-lbs).

5. Reconnect Battery and Test Drive

Reconnect the battery’s negative terminal.
Start the engine and let it idle, observing for any abnormal noises or warning lights.
Take the vehicle for a short test drive to ensure the check engine light does not reappear.
