What Could Trigger the Check Engine Light?
The following reasons could be some common causes for why your Hyundai Sonata check engine light — or check engine light on any model — may be on:
- Mass Airflow Sensor: This sensor, commonly referred to as just the MAF sensor, is an engine component that measures how much air is flowing through the engine so the correct amount of fuel can be added. 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!
How Can I Fix the Problem?
There are even more serious problems that can occur to make your Hyundai model’s check engine light come on, so take a look below for what you can do when you notice any dashboard light come on:
- First, it’s smart to get a grasp of what every dashboard light is and 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, as well as any other dashboard light.
- When your car’s check engine light is on, be sure to try and discover 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. There’s actually a difference you may notice in the color of your check engine light, too! Yellow lights indicate that there’s a problem you should investigate soon, whereas a red check engine light comes on in the event that something important malfunctions and you need to stop immediately.
- Like we said above, the check engine light may be on simply due to an unsecured gas cap. So, make sure it’s tightened and try to restart your car after a few minutes to see if the light goes back off.
- You may just need to reduce the weight of your car, so if you have plenty of materials or equipment riding along with you, try unloading it as soon as possible.
