Why Is My Hyundai Check Engine Light On?

Have you recently been driving down the Humboldt roads and your Hyundai check engine light came on? This can be both confusing and inconvenient, especially if you’re in a hurry; however, it might not be anything serious. In most cases, your Hyundai Sonata check engine light lets you know it’s time to bring your vehicle to your local Jackson dealership for maintenance. Learn more about the Hyundai check engine light with the experts at Allen Samuels Hyundai today! For more information, feel free to contact us anytime!

How Can I Fix the Check Engine Light?

You can fix your Hyundai check engine light in a few different ways. Fixing these small issues could reset the check engine light automatically. It’s important to note that in some cases, the Hyundai Elantra check engine light appears for more serious issues that must immediately be addressed. Here’s a helpful guide to follow when your Hyundai check engine light comes on:

  • The first thing to do is know exactly what each light on the dashboard means, as this could help you diagnose the issue. You should always consult your vehicle owner’s manual to determine what each light signifies.
  • You’ll find that each Hyundai check engine light can be traced to a code. The yellow means there is an issue that should be checked soon. The red is more critical and means that one of the main components has malfunctioned, and you should head to your local Lexington-area service center.
  • When you notice your check engine light on the dashboard, you should see if you notice any immediate issues such as overheating or low oil. If you believe it is something more serious, we recommend pulling over safely and shutting off the engine. 
  • If the issue persists and you can’t seem to figure it out, you can always trust the expert technicians at Allen Samuels Hyundai to get you back out on the road. Our experts know each code inside the vehicle and can find any issues that need attention. 

What Triggers The Check Engine Light?

Your Hyundai check engine light might come on for a variety of reasons, including something as small as the gas cap not being tightened to a more serious issue. Let’s check out some of the most common Hyundai dashboard lights you might see on your Jackson drives below:

  • Mass Airflow Sensor: The Mass Airflow Sensor (also known as the MAF), measures how much air is flowing through the engine so the correct amount of fuel can be added to the mixture. If your MAF is not working properly, you’ll see the check engine light appear on the dashboard. Issues with the Mass Airflow Sensor could cause stalling, increased emissions, and low fuel economy. This can be fixed just by changing the air filter. 
  • Oxygen Sensor: The oxygen sensor detects the amount of oxygen in the exhaust to see how much fuel is being consumed. If the oxygen sensor is not properly cared for, it could cause issues with your catalytic converter.
  • Catalytic Converter: The catalytic converter converts carbon monoxide into safer compounds to create less pollution. Issues with this component could increase your gas mileage and reduce the quickness of acceleration 
  • Loose Gas Cap: The most simple problem that can cause your check engine light to come on is an unsecured gas cap, so make sure you check that first!
