Solution

1. Preparation

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

2. Retrieve and Address Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "On" position without starting the engine.
Read the error codes and make note of any relevant codes related to engine performance.

3. Inspect Oil Level and Quality

Remove the dipstick and wipe it clean.
Reinsert it and remove it again to check the oil level; add oil if necessary.
Inspect the oil's color and consistency; if it appears milky or contains debris, a full oil change may be required.

4. Check Oil Filter Installation

Use the oil filter wrench to tighten or replace the oil filter if it is leaking.
Ensure the oil filter’s rubber O-ring is properly seated and not stuck to the engine block.

5. Secure All Connections

Inspect the engine compartment for any loose or disconnected wires, especially near the oil change area.
Reconnect any loose connectors and ensure they are secure.

6. Clear Error Codes

Use the OBD-II scanner to clear any error codes after addressing issues.
Turn off the ignition and wait a moment before restarting the engine to see if the check engine light remains off.
