Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, oil filter wrench, rags for cleanup.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Check Engine Codes

Use the OBD-II scanner to read any stored diagnostic trouble codes (DTCs).
Document the codes for reference.

3. Inspect Oil Level

Pull out the dipstick, wipe it clean, reinsert it, and check the oil level.
If the oil level is low, add the appropriate type and amount of oil.

4. Inspect Oil Filter

Use the oil filter wrench to remove the oil filter.
Check the rubber O-ring on the old filter; if it is stuck to the engine, it can cause leaks.
Install a new oil filter, ensuring it is tight but not over-torqued.

5. Inspect Oil Drain Plug

Using a socket wrench, check the torque on the oil drain plug; it should be tightened to the manufacturer's specification (typically around 20-25 lb-ft).
If leaking, replace the washer or the drain plug if damaged.

6. Reset the Check Engine Light

Clear the codes using the OBD-II scanner.
Start the engine and monitor for any return of the check engine light.
