Solution

1. Preparation

Gather tools such as an OBD-II scanner, socket set, and torque wrench.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Scan for Codes

Use the OBD-II scanner to pull any diagnostic trouble codes (DTCs) from the engine control unit (ECU).
Record the codes for further analysis.

3. Inspect Oil Level and Quality

Remove the dipstick and wipe it clean.
Reinsert and remove to check the oil level; add oil if necessary.
Verify that the oil type matches manufacturer specifications.

4. Check Oil Filter Installation

Inspect the oil filter for signs of oil leaks or improper installation.
If leaking, remove the filter, apply a new gasket, and reinstall it securely, tightening it to manufacturer specifications.

5. Verify Electrical Connections

Examine the wiring harnesses and connectors for any disconnections or damage.
Reconnect or repair any loose connections that were disturbed during the oil change.

6. Reset Check Engine Light

After addressing any issues, use the OBD-II scanner to clear any stored trouble codes.
Cycle the ignition to check if the check engine light remains off.
