Why Is My Hyundai Check Engine Light On?

Vehicle issues won’t always pop up at the most convenient time. That being said, when you’re prepared with the proper information and plans, you can address any issues that arise with ease. So, how do you handle your Hyundai check engine light being on? It’s important to know that your check engine light indicates that your vehicle is ready for maintenance or needs repair. It could be minor or serious but the best thing to do is to bring your vehicle to our Brenham service center for our technicians to inspect. We’re here to help you get back out onto the Navasota and College Station roads as quickly as possible.

How Can I Fix a Hyundai Check Engine Light?

Typically, you can fix minor maintenance issues on your own. When you make these minor fixes, the check engine light should reset automatically, but you may need to reset it manually if it’s being stubborn. However, sometimes your Hyundai check engine lights come on for more serious reasons. Read below to see what steps you should take when your check engine light comes on:

• First, it’s smart to get a grasp of what every dashboard light is and what it signifies, so take a look at your vehicle’s owner’s manual. By reading your manual, you can learn all about the Hyundai Elantra check engine light, the Hyundai Sonata check engine light, as well as any other Hyundai dashboard light.
• As you’ll see in your owner’s manual, your Hyundai dashboard lights have a color code to them. Yellow lights indicate that there’s a problem you should investigate soon, whereas a red check engine light comes on when an important component has malfunctioned, and you need to stop immediately.
• When your car’s check engine light is on in Bryan, be sure to try and find any glaring problems that could be the cause, and look for signs of overheating or low oil pressure. In the case that you believe there is a more serious problem, then be sure to find a safe spot to park and shut off the engine.
• In the case that you can’t discover what the problem is yourself, you can always bring your vehicle into our service center in Brenham. The expert technicians at Hyundai of Brenham will be able to read your engine’s code, diagnose the problem, and fix it in no time.

What Triggers The Check Engine Light?

The Hyundai Elantra check engine light or Hyundai Sonata check engine light on your dashboard acts as a “catch-all” light for vehicle maintenance problems. It can indicate a major mechanical failure in your vehicle, or it can be something simple like your gas cap being improperly screwed on. We’ve listed some common reasons your Hyundai dashboard lights may come on while you’re driving on Navasota roads 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 malfunctioning, your check engine light will illuminate. Problems with the mass airflow sensor may lead to stalling, increased emissions, and less fuel efficiency. Changing your Hyundai’s air filter can solve the problem.
• Oxygen Sensor: The oxygen sensor in a car is used to detect how much oxygen is in the exhaust to measure how much fuel is being used. If not taken care of, your vehicle’s catalytic converter may malfunction, on top of plummeting fuel efficiency.
• Catalytic Converter: The catalytic converter converts carbon monoxide into safer compounds in order to create less pollution. If you have a problem with this piece, your gas mileage may be affected and you could even have reduced 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!

These recommendations may become outdated over time or differ from recommendations for older vehicles. To ensure accuracy, always consult your owner’s manual or a certified OEM mechanic.
