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

When your check engine light comes on, this could be as simple as tightening or replacing your gas cap. Still, 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 expensive repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady and continuous glow ordinarily means something less serious but a flashing check engine light indicates that your vehicle’s engine is in meaningful trouble and helpful service is required swiftly. If your check engine light is flashing in your Genesis G90, we exceedingly advise not to drive the car and schedule Genesis service today. Below is a list of the most typical reasons your check engine light can come on:

• Your Genesis G90 has a vacuum leak. Every Genesis G90 has a vacuum system that performs a wide variety of functions. The vacuum system also 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.
• Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak extreme havoc on your Genesis G90 if it’s not installed correctly. These aftermarket components and accessories can drain the battery, trigger the check engine light, or even limit the car 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 accurately and aren't causing any issue. Getting accessories, particularly aftermarket parts and accessories, or using OEM components first place might cost a little bit more but could support you save considerably from having to get poor work and damage caused by poor installation work corrected.
• New Spark Plugs or Plug Wires are necessary for your Genesis G90. The spark plugs are the part of your engine that ignites the air/fuel mixture in the combustion chamber of your car. 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 undergo a evident 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 obstructed 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 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 frequently caused by repeatedly neglected maintenance, which is why Genesis of Peoria offers a free multi-point inspection with every Genesis service. If you have an issue with your catalytic converter and don't get it repaired, your Genesis G90 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 perilous problems from overheating.
• The battery is low or dead. The battery in your Genesis G90 is every essential. Without a car battery, your car won’t start, light up the road in front, play the radio or charge your phone. Today’s car 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.
• 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 expeditiously and your car will be less efficient when it comes to fuel economy. So what occurs if I don’t change your O2 sensor? A broken sensor can not only affect your miles per gallon, but it can cause significant damage to your catalytic converter and your Genesis G90's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the absolutely correct mixture of air and fuel that enters the cylinders in your engine. A broken O2 sensor can also cause a car to fail an emissions test.
• One of the most regular and frequent cause is that your Genesis G90 gas cap is loose, broken or missing. The gas cap for your Genesis G90 serves multiple purposes. It prevents dangerous gas fumes from being released when you aren't driving, it seals the fuel system and helps cultivate pressure within the fuel tank. What occurs if you have a broken 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 expensive. Luckily, to change a gas cap isn't expensive. If your check engine light turns on instantly after you put gas in your 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 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 quick replace in the position of the throttle pedal, this could be a vital sign of a broken mass airflow sensor.

Check Engine Light Service 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 precisely 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, peaceful breath and realize the light coming on doesn’t mean you have to pull the car over to the side of the road and call a tow truck, but it is suggested that you get your Genesis G90 checked swiftly. Ignoring that warning could end up causing significant, huge damage to expensive engine components.

When your 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 correct, a computer turns on your check engine light. This amber or yellow light is typically 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 expeditiously 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 likewise 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 absolutely right issue and repair it.
