Unsure why the Hyundai check engine light has appeared on your dashboard digital display? Usually, this light will ignite when your car requires maintenance or because an issue with your engine has been detected. Here, North Freeway Hyundai explains common reasons why your Hyundai Elantra check engine light or Hyundai Sonata check engine light will come on and what you can do to address them. And remember, you can always schedule service with us near Houston to take care of any problems that arise!

What Triggers the Hyundai Check Engine Light?

Generally speaking, your Hyundai check engine light serves as a “catch-all” to alert you to necessary vehicle maintenance. It might turn on because of a major issue, or it may light up simply because your gas cap is loose. Below are some common reasons that your Hyundai Sonata check engine light may appear as you drive around Spring.

  • Loose Gas Cap: The simplest scenario that triggers your Hyundai check engine light is a loose gas cap. Check this first, as it is a very easy fix!
  • Mass Airflow Sensor: The Mass Airflow Sensor (MAF) monitors the amount of air flowing through the engine so that proper fuel levels will be added. If the MAF malfunctions, your Hyundai check engine light will illuminate. Typically, changing your air filter will solve the problem. You can order an air filter online through our parts center.
  • Oxygen Sensor: This component detects oxygen levels in the exhaust to determine how much fuel is being used. If you don’t address issues with your oxygen sensor, your Hyundai’s catalytic converter might stop working. You will also experience reduced fuel economy returns.
  • Catalytic Converter: The catalytic converter takes carbon monoxide and converts it into safer components to reduce pollution. As previously mentioned, issues with this component will negatively influence your gas mileage, and you may also experience poor acceleration.

How to Turn Off Hyundai Check Engine Light

If you already brought your Hyundai to the North Freeway Hyundai service center, and you’re certain that there are no issues with your vehicle, then you may need to reset your Hyundai check engine light manually. One method to do so involves disconnecting your car battery and then reconnecting it after waiting a couple of minutes. You may need to drive a few miles after this until the light disappears. If this doesn’t work, you can always come back to North Freeway Hyundai to have our certified technicians reset the light for you.
