Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, and battery terminal wrench.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Address Issues

Use the OBD-II scanner to retrieve any trouble codes. If codes are present, repair the underlying issue (e.g., replace faulty sensors, fix leaks).
Tighten or replace the gas cap if it was determined to be the cause of the CEL.

3. Reset the Check Engine Light

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Follow the scanner's prompts to navigate to the option to clear or erase trouble codes.
Confirm the action and wait for the scanner to indicate that the codes have been cleared.
Disconnect the scanner.

B. Manual Reset via Battery Disconnect

Open the hood and locate the negative battery terminal.
Use a socket wrench to loosen the negative terminal clamp.
Remove the negative terminal and keep it disconnected for at least 15 minutes.
Reconnect the negative terminal and tighten it securely.
Start the engine and check if the check engine light has turned off.
