Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, oil filter wrench, and rags for cleanup.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to reset the engine control module (ECM) if applicable.

2. Check Oil Level

Remove the dipstick, clean it with a rag, and reinsert it.
Pull it out again to check the oil level; add oil if it is below the recommended level.
Ensure that the oil used matches the specifications in the owner’s manual.

3. Inspect Oil Filter

Use an oil filter wrench to remove the oil filter if it is leaking.
Inspect the rubber gasket on the old filter to ensure it was not stuck to the engine.
Install a new oil filter, ensuring it is tightened to the manufacturer’s torque specifications (usually hand-tight plus a quarter turn).

4. Check for Leaks

With the engine running, look for any oil leaks around the oil pan and filter.
If leaks are detected, tighten connections or replace gaskets as necessary.

5. Reset Engine Light

Reconnect the negative battery terminal.
Use an OBD-II scanner to clear any stored trouble codes that may have triggered the check engine light.
