What could cause the check engine light to come on in a 2020 Hyundai Sonata?

When your check engine light comes on, this could be as comfortable as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a precarious problem that could cause precarious damage to your engine and come with a substantial repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady glow generally means something less precarious but a flashing check engine light indicates that your vehicle’s engine is in precarious trouble and service is needed quickly. If your check engine light is flashing in your 2020 Hyundai Sonata, we chiefly recommend not to commute the vehicle and schedule Hyundai service now. Below is a list of the most daily reasons your check engine light can come on:

  • One of the most accepted and frequent cause is that your 2020 Hyundai Sonata gas cap is loose, damaged or missing. The gas cap for your 2020 Hyundai Sonata serves multiple purposes. It prevents gas fumes from being released when you aren't driving, it seals the fuel system and helps maintain pressure within the fuel tank. What happens if you have a harmful fuel cap? If your gas cap is old or has a ruptured seal, you can lose fuel through evaporation which will result in more trips to the pump. Luckily, to replace a gas cap isn't expensive. If your check engine light turns on hastily after you put gas in your 2020 Hyundai Sonata, authentic thing you should check is to make confident the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
  • The battery is low or dead. The battery in your 2020 Hyundai Sonata is every needed. Without a car battery, your car won’t start, light up the road ahead, play the radio or charge your phone. Today’s car batteries last much longer than they did a lot decades ago, and they don't really require maintenance. The price of a new one depends on the type of Hyundai you drive, but check our current service coupons and specials.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak havoc on your 2020 Hyundai Sonata if it’s not installed properly. These aftermarket parts and accessories can discard the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound prevalent, bring your Sonata to Hyundai and have our team of certified mechanics ensure that your aftermarket items were installed perfectly and aren't causing any issue. Getting accessories, especially aftermarket parts and accessories, or using OEM parts authentic place might cost a little bit more but could save you money from having to get poor work and damage caused by poor installation work corrected.
  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Hyundai Sonata is what determines how much fuel is needed to run your engine efficiently by measuring the amount of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to cognizant changes, like altitude. If your Hyundai Sonata is having trouble starting, idling rough or has a agile change in the position of the throttle pedal, this could be a sign of a harmful mass airflow sensor.
  • New Spark Plugs or Plug Wires are needed for your 2020 Hyundai Sonata. The spark plugs are the part of your engine that ignites the air/fuel mixture in the combustion chamber of your vehicle. This explosion is what moves the pistons and makes the engine run. The spark plug wires deliver the spark from the ignition coil to the spark plugs. If your spark plugs or spark plug wires are harmful or old, you will experience poor performance and reduced power. In some extreme cases, your engine will have trouble starting or continuing to run. Worn spark plugs and plug wires can cause clogged catalytic converter or damage to ignition coils and O2 sensors, best to more expensive repairs.
  • Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, admitted as the O2 sensor, measures the amount of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be less competent when it comes to fuel economy. So what happens if I don’t replace your O2 sensor? A faulty sensor can not only affect your miles per gallon, but it can cause damage to your catalytic converter and your 2020 Hyundai Sonata's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to select the right mixture of air and fuel that enters the cylinders in your engine. A harmful O2 sensor can also cause a car to fail an emissions test.
  • Your 2020 Hyundai Sonata has a vacuum leak. Every Hyundai Sonata has a vacuum system that performs a wide variety of functions. The vacuum system also helps reduce harmful emissions by routing the fumes as gasoline evaporates through the engine. If you notice that your RPM is high in idle or randomly surges, a vacuum leak could be the cause. Over time, vacuum hoses can dry out and crack, especially if they’re exposed to important heat or extreme cool.
  • Your catalytic converter is harmful or going harmful. The catalytic converter is a part of your 2020 Hyundai Sonata’s exhaust system. The catalytic converter's function is to turn the carbon monoxide created by the combustion process into carbon dioxide. A damaged catalytic converter is usually caused by neglected maintenance, which is why Nalley Hyundai offers a complimentary multi-point inspection with every Hyundai service. If you have an issue with your catalytic converter and don't get it repaired, your 2020 Hyundai Sonata will not pass an emissions test, show a lack of engine performance and will negatively affect your fuel economy. Your car may run at a higher temperature, too, which can cause other problems from overheating.
