Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and set the parking brake.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Check Engine Oil Level

Reconnect the battery.
Remove the dipstick, clean it with a rag, and reinsert it.
Pull the dipstick out again and check the oil level; add oil if necessary.
If oil level is low, inspect for leaks and add the correct oil type as specified in the owner's manual.

3. Inspect Oil Filter

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

4. Reset Engine Light

With the diagnostic scanner, clear the error codes after verifying any issues have been resolved.
Allow the vehicle to run for a few minutes and then re-check for any new codes.

5. Final Check

Take the vehicle for a short test drive to see if the engine light reappears.
Monitor the oil pressure gauge during the drive.
