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

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 meaningful 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 serious trouble and helpful service is needed immediately. If your check engine light is flashing in your Hyundai, we highly recommend not to drive the vehicle and schedule Hyundai service today. Below is a list of the most common reasons your check engine light can come on:

  • 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 immediately and your car will be less efficient 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 serious damage to your catalytic converter and your Hyundai 's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the definitely correct mixture of air and fuel that enters the cylinders in your engine. A faulty O2 sensor can again cause a vehicle to fail an emissions test.
  • The battery is low or dead. The battery in your Hyundai is each important. Without a vehicle battery, your vehicle won’t start, light up the road ahead, 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 Hyundai you drive, but check our current service coupons and specials.
  • Your Hyundai has a vacuum leak. Each Hyundai 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, especially if they’re exposed to intense heat or extreme cold.
  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Hyundai is what determines how much fuel is required 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 Hyundai is having trouble starting, idling rough or has a sudden speedy change in the position of the throttle pedal, this could be a important sign of a faulty mass airflow sensor.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak extreme havoc on your Hyundai if it’s not installed accurately. These aftermarket components and accessories can drain the battery, trigger the check engine light, or even prevent the car from starting. If these issues sound familiar, bring your to Hyundai and have our team of talented certified mechanics assure that your aftermarket items were installed correctly and aren't causing any issue. Getting accessories, especially aftermarket parts and accessories, or utilizing OEM components first place might cost a little bit more but could help you save substantially from having to get poor work and damage caused by poor installation work corrected.
  • One of the most common and frequent cause is that your Hyundai gas cap is loose, broken or missing. The gas cap for your Hyundai serves various 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 happens if you have a faulty 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 pricey. Luckily, to replace a gas cap isn't pricey. If your check engine light turns on swiftly after you put gas in your Hyundai, 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.
  • New Spark Plugs or Plug Wires are required for your Hyundai. 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 experience a conspicuous 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 pricey repairs.
  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your Hyundai ’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 repeatedly neglected maintenance, which is why Coggin Automotive Group offers a complimentary multi-point check with each Hyundai service. If you have an issue with your catalytic converter and don't get it repaired, your Hyundai 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.

Will the check engine light reset itself?

The check engine light on your Hyundai will frequently 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 rapidly turn itself off. Also, if your catalytic converter is working accurately, 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 Hyundai 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 Coggin Automotive Group so the light and code can be double-checked and reset.

How much does it cost to get the engine light checked?

The check engine light warns of issues ranging from a gas cap that's not correctly tightened to a more serious failure like a bad catalytic converter or a problem with one of the car's oxygen sensors, so it good to get the proper code reading and diagnosis. The average cost for a check engine light diagnosis & testing is generally between $88 and $111. The good news, Coggin Automotive Group offers totally complimentary multi-point inspections and free diagnostics, in most cases, to help determine the cause of your check engine light.

How many miles can you drive with the check engine light?

The safest bet is to decipher the code and then plan your strategy accordingly. It could be anything from a bad sensor to plug wires needing to be replaced. Since each check engine code has its own level of severity, it is generally difficult to predict how many miles you can be secure in driving with the warning light on. If you check engine light is flashing, we advocate that you pull over and contact Coggin Automotive Group to help determine if your car is secure to drive in or if we advocate a tow truck.

Check Engine Light Service Hyundai

What do you do when you’re driving along in your Hyundai and suddenly, a yellow light illuminates on your dash and says "Check Engine". If you’re like most Hyundai owners, your heart sinks drastically because you may have specifically 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 vehicle over to the side of the road and call a tow truck, but it is suggested that you get your Hyundai checked rapidly. Ignoring that warning could end up causing major, major damage to pricey engine parts.

When your Hyundai '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 generally 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 Hyundai auto repair mechanics at Coggin Automotive Group. There are still a number of essentially 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 correct issue and repair it.
