Check Engine Light Service 2018 Genesis G90

What do you do when you're driving along in your Genesis G90 and suddenly, a yellow light illuminates on your dash and says "Check Engine". If you're like most Genesis owners, your heart sinks drastically because you may have absolutely idea about what that light is trying to tell you or how you should react. The fear of the unknown (or the cost of the unknown) can be just as stressful. But take a deep, calm breath and realize the light coming on doesn't mean you have to pull the vehicle over to the side of the road and call a tow truck, but it is suggested that you get your 2018 Genesis G90 checked instantly. Ignoring that warning could end up causing considerable, major damage to expensive engine parts.

When your 2018 Genesis G90's ECM (electronic control module), which is the vehicle's onboard computer, finds a problem in the electronic control system that it can't right, a computer turns on your check engine light. This amber or yellow light is ordinarily labeled “check engine” or “service engine soon”, or the light may be nothing more than a picture of an engine, or a picture of the engine with the word “check.”

When the light turns on, the ECM stores an engine code or “trouble code” in its memory that can swiftly identify the issue, whether it's a sensor or a failing engine part. This code is read with an electronic scan tool that is used by our Genesis auto repair mechanics at Genesis of Peoria. There are also a number of relatively inexpensive code readers that are designed for do-it-yourselfers, should you choose that route too. While this code will tell you the issue that is detected, a true diagnosis still requires an experienced professional to determine the explicitly right issue and repair it.

Will the check engine light reset itself?

The check engine light on your 2018 Genesis G90 will ordinarily shut itself off if the issue or code that caused it to turn on is fixed. For instance, if the cause of your check engine light coming on was a loose gas cap, if it's tightened, the light will instantly turn itself off. Also, if your catalytic converter is working properly, and you did a lot of stop-and-go driving, that may have turned on the check engine light due to the high usage of the converter. In most cases, your 2018 Genesis G90 light will go off after about 20-40 miles. If you drive over that amount and the light is still on, you will need to bring it in to Genesis of Peoria so the light and code can be double-checked and reset.

If the check engine light is flashing, this means that there is a serious issue and it is suggested to service your Genesis G90 promptly. This question is not very simple because it all depends on the severity of the issue. If the cause is a minor issue, such as a loose gas cap, it should be safe to drive. This is typically indicated by a steady glow of the check engine light. If you notice a difference in the performance of the vehicle, it could be an indication of a more serious problem. Call the experts at Genesis of Peoria by dialing 4804707776 so you can describe the issues. Or decrease your speed and bring your 2018 Genesis to our certified mechanics as soon as imaginable.

What could cause the check engine light to come on in a 2018 Genesis G90?

When your check engine light comes on, this could be as simple as tightening or replacing your gas cap. Again, the check engine light could still be a warning of a serious problem that could cause serious damage to your engine and come with a hefty and costly repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady and continuous glow usually means something less serious but a flashing check engine light signifies that your vehicle's engine is in significant trouble and helpful service is needed immediately. If your check engine light is flashing in your 2018 Genesis G90, we tremendously advise not to drive the vehicle and schedule Genesis service today. Below is a list of the most common reasons your check engine light can come on:

  • New Spark Plugs or Plug Wires are necessary for your 2018 Genesis G90. 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 smooth. The spark plug wires deliver the spark from the ignition coil to the spark plugs. If your spark plugs or spark plug wires are bad or old, you will endure a evident poor performance and decreased 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, leading to more expensive repairs.
  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2018 Genesis G90's exhaust system. The catalytic converter's function is to turn the carbon monoxide created by the combustion process into carbon dioxide. A broken catalytic converter is usually caused by consistently neglected maintenance, which is why Genesis of Peoria offers a complimentary multi-point inspection with every Genesis service. If you have an issue with your catalytic converter and don't get it repaired, your 2018 Genesis G90 will not pass an emissions test, show a lack of engine performance and will negatively affect your fuel economy. Your vehicle may run at a higher temperature, too, which can cause other dangerous problems from overheating.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak extreme havoc on your 2018 Genesis G90 if it's not installed properly. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even limit the vehicle from starting. If these issues sound familiar, bring your G90 to Genesis and have our team of talented certified mechanics ensure that your aftermarket items were installed properly and aren't causing any issue. Getting accessories, particularly aftermarket parts and accessories, or using OEM parts first place might cost a little bit more but could assist you save substantially from having to get poor work and damage caused by poor installation work corrected.
  • Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, known as the O2 sensor, measures the amount of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns more instantly and your vehicle will be less efficient when it comes to fuel economy. So what occurs if I don't replace your O2 sensor? A damaged sensor can not only affect your miles per gallon, but it can cause serious damage to your catalytic converter and your 2018 Genesis G90's spark plugs. The O2 sensor sends data to the vehicle's onboard computer to determine the absolutely right mixture of air and fuel that enters the cylinders in your engine. A damaged O2 sensor can again cause a vehicle to fail an emissions test.
  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Genesis G90 is what determines how much fuel is necessary 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 certain changes, like altitude. If your Genesis G90 is having trouble starting, idling rough or has a sudden rapid change in the position of the throttle pedal, this could be a critical sign of a damaged mass airflow sensor.
  • The battery is low or dead. The battery in your 2018 Genesis G90 is every important. Without a vehicle battery, your vehicle won't start, light up the road in front, play the radio or charge your phone. Today's vehicle batteries last much longer than they did a few decades ago, and they don't genuinely require maintenance. The price of a new one depends on the type of Genesis you drive, but check our current service coupons and specials.
  • One of the most typical and frequent cause is that your 2018 Genesis G90 gas cap is loose, broken or missing. The gas cap for your 2018 Genesis G90 serves multiple purposes. It prevents hazardous gas fumes from being released when you aren't driving, it seals the fuel system and helps maintain pressure within the fuel tank. What occurs if you have a damaged 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 and be more costly. Luckily, to replace a gas cap isn't expensive. If your check engine light turns on quickly after you put gas in your 2018 Genesis G90, first thing you should check is to make sure the cap isn't loose — or that it's still on your car's roof or at the fuel pump.
  • Your 2018 Genesis G90 has a vacuum leak. Every Genesis G90 has a vacuum system that performs a wide variety of functions. The vacuum system again helps lower adverse 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, particularly if they're exposed to intense heat or extreme cold.
