The 2018 Hyundai Sonata’s check engine light can be reset in a number of ways, but occasionally it will turn off on its own after some time behind the wheel. You can also unplug the battery, wait for about 20 minutes, and then plug it back in to reset the check engine light on your car. You will need to utilize an electronic scan tool to identify the issue and resolve it if neither of those solutions work. You may check to see whether the gas cap is loose, which is one of the common reasons why the light might be on, without the need for a scanner. If that isn’t the issue, you’ll need to use the scanner to identify the issue, resolve it, and then reset it using the scanner.
Connect an OBD II scanner to the Hyundai Sonata’s appropriate port, then follow the instructions on the scanner to reset the check engine light.
