Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Wear safety glasses and gloves for protection.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's OBD-II port, usually located under the dashboard.
Turn the ignition to the "On" position without starting the engine.
Follow the scanner instructions to read and record any error codes.

3. Address Error Codes

Research the recorded error codes to determine the underlying issues.
If the codes indicate a specific failure (e.g., oxygen sensor, catalytic converter), proceed to replace or repair the affected components.

4. Reset the Check Engine Light

With the OBD-II scanner still connected, navigate to the option to clear or reset the trouble codes.
Confirm the reset process as instructed by the scanner.
Disconnect the scanner from the OBD-II port.

5. Test Drive

Start the vehicle and allow it to run for a few minutes.
Take the vehicle for a test drive to allow the engine control module (ECM) to recalibrate and monitor for any new codes.
