Why Is My Hyundai Check Engine Light On?

check-engine-light

Your Hyundai will let you know when trouble’s coming under the hood using its check engine light. But, how urgent is the problem, and what is that problem, specifically? Those are the important questions that our service center is often asked by the St Louis drivers of new vehicles and used vehicles alike. Truthfully, your check engine light can mean anything from a major engine issue to a loose gas cap. Let’s dive into some of the more common reasons and find out how and when to bring your car, truck, van, or SUV in for service.

Why Do I Have a Check Engine Light?

Hidden issues with your engine often manifest as a check engine light on your dashboard. Along with that light, a code is generated that can be displayed by a reader that tells you what the issue is. You can buy a code reader to check out what’s wrong with your vehicle right away, or you can bring it into the Suntrup Hyundai South service center for one of our experts to discern. Regardless, the right equipment will immediately tell you what the problem is and bring you to a faster resolution.

Malfunction Indicator Light Hyundai Meaning

Another term for the check engine light is the Malfunction Indicator Light (MIL). If you see the malfunction indicator light on your Hyundai, then this usually indicates a malfunction with the emission control system. If you see this light on, you should have your Hyundai serviced as soon as you can since this can be potentially dangerous to have on your dashboard while driving through Jefferson County. Schedule service with us if you see this light flashing on your Hyundai dashboard.

Why Is My Check Engine Light On?

The most common culprits for a check engine light in the St Charles area might surprise you. It could be that your engine air filter needs to be changed, but these five are most often what triggers it:

  • Oxygen sensor
  • Catalytic converter
  • Mass airflow sensor
  • Spark plug wire
  • Gas Cap

Please note, a flashing check engine light indicates a severe issue that should be addressed by a licensed mechanic immediately. Most of the time, though, your engine light will typically appear as a steady amber, orange, or yellow glow. In these cases, just head to the garage as soon as you are available to do so. Be sure to use our service specials to save on your next visit.
