A malfunctioning MAF can be fixed by changing the air filter, which you can buy at a Hyundai parts center.

Another common issue that can result in a check engine light is a problem with the oxygen sensor, which monitors the amount of oxygen in the exhaust. A malfunctioning oxygen sensor can lead to catalytic converter failure and reduce fuel economy.

Catalytic converter

If you notice a noticeable drop in fuel efficiency and high fuel consumption while driving, you may have a problem with your Hyundai Sonata’s catalytic converter. In order to diagnose the problem, you will need to perform several diagnostic tests and take your car to a professional mechanic. A catalytic converter can fail because of contamination, overheating, or physical damage. This condition may also occur as a result of problems with the ignition system or worn spark plugs.

To diagnose the problem, first you should check the temperature of your Hyundai Sonata’s catalytic converter. To check this, unbolt the oxygen sensor located near the catalytic converter. If it shows a temperature difference of over 10 degrees Celsius or fifty degrees Fahrenheit, your Hyundai Sonata has a clogged catalytic converter.

Oil plug failure

If you notice that your Hyundai’s Check Engine Light is on, there is a good chance that your car is having an oil plug failure. This can cause your Hyundai to run poorly and you should bring it to a qualified mechanic for a professional diagnosis. If you suspect oil plug failure, you should first turn down the speed of your car.

In addition to a failure, you may also see the light illuminate during a drive. If you notice this warning, you should take the vehicle to a qualified mechanic as soon as possible. The problem could be as simple as a cracked fuel tank.

Misfiring engine

If you have a Hyundai Sonata that flashes the check engine light, you should get your vehicle serviced. The problem could be as simple as a blown spark plug, or it could be as serious as a damaged catalytic converter. Regardless of the cause, you should never drive your vehicle with the check engine light on. It can cause serious damage and can cost you a lot of money to repair.

To diagnose the problem, you need to know the code. Hyundai has an easy-to-use online tool that will quickly and easily show you the error code. In some cases, you may be able to diagnose the problem on your own. If you need help, call a Hyundai certified mechanic. Remember that aftermarket parts can be problematic and should be checked by a qualified mechanic. Even though they may cost more than original equipment parts, they will prevent unnecessary damage caused by improper installation.
