Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to reset the system.
Wait for at least 10 minutes before proceeding to ensure all systems are powered down.

2. Inspect and Tighten Components

Oil Filter: Remove the oil filter (if necessary) and check the rubber O-ring for damage; replace if needed. Reinstall the filter, tightening to the manufacturer’s specified torque (usually hand-tight plus ¾ turn).
Drain Plug: Check the drain plug for proper installation and torque to the manufacturer’s specifications (typically 30-40 ft-lbs).
Connectors: Inspect and reconnect any electrical connectors that may have been loosened during the oil change.

3. Clear Error Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any error codes that were identified previously.
Turn the ignition on without starting the engine to allow the system to reset.

4. Test Drive and Monitor

Start the engine and let it idle for a few minutes while monitoring for any unusual sounds or issues.
Take the vehicle for a short test drive to ensure that the check engine light does not reappear.
