Check engine light on

For a Genesis vehicle, the major reason why the check engine light would persistently stay on would be due to issues that have to do with malfunction of the spark plug. It could do the car owner some good to check for that. Issues that have to do with fuel delivery can also be a major culprit. Sometimes, it could be due to a sensor that is faulty. When the mass airflow sensor is faulty, it can make the check engine light to stay on. And lastly, if the gas cap is damaged, the check engine light is likely to stay on.

Has there been an oil change recently on the vehicle?
