Hyundai Tucson Check Engine Light

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

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 also be a warning of a serious problem that could cause serious damage to your engine and come with a hefty and pricey 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 reveals that your vehicle’s engine is in significant trouble and helpful service is necessary expeditiously. If your check engine light is flashing in your Hyundai Tucson, we extremely endorse not to drive the car and schedule Hyundai service today. Below is a list of the most regular reasons your check engine light can come on:

• Your Hyundai Tucson has a vacuum leak. Each Hyundai Tucson 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.
• Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak extreme havoc on your Hyundai Tucson if it’s not installed correctly. 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 Tucson to Hyundai and have our team of talented certified mechanics ensure that your aftermarket items were installed perfectly and aren't causing any issue. Getting accessories, especially aftermarket parts and accessories, or utilizing OEM parts first place might cost a little bit more but could help you save considerably 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 promptly and your vehicle will be less efficient when it comes to fuel economy. So what results if I don’t replace your O2 sensor? A defective sensor can not only affect your miles per gallon, but it can cause significant damage to your catalytic converter and your Hyundai Tucson's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the absolutely appropriate combination of air and fuel that enters the cylinders in your engine. A defective O2 sensor can again cause a vehicle to fail an emissions test.
• Your catalytic converter is bad or going bad. The catalytic converter is a part of your Hyundai Tucson’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 ordinarily caused by regularly neglected maintenance, which is why Larry H. Miller Hyundai Peoria offers a complimentary multi-point examination with each Hyundai service. If you have an issue with your catalytic converter and don't get it repaired, your Hyundai Tucson 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 perilous problems from overheating.
• The battery is low or dead. The battery in your Hyundai Tucson is each essential. 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 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.
• One of the most typical and frequent cause is that your Hyundai Tucson gas cap is loose, broken or missing. The gas cap for your Hyundai Tucson serves various purposes. It prevents dangerous gas fumes from being released when you aren't driving, it seals the fuel system and helps control pressure within the fuel tank. What results if you have a defective 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 swiftly after you put gas in your Hyundai Tucson, 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 needed for your Hyundai Tucson. The spark plugs are the part of your engine that ignites the air/fuel combination 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 blocked catalytic converter or damage to ignition coils and O2 sensors, leading to more expensive repairs.
• Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Hyundai Tucson 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 certain changes, like altitude. If your Hyundai Tucson is having trouble starting, idling rough or has a sudden quick change in the position of the throttle pedal, this could be a vital sign of a defective mass airflow sensor.

Will the check engine light reset itself?

The check engine light on your Hyundai Tucson will usually shut itself off if the issue or code that caused it to turn on is fixed. For example, if the cause of your check engine light coming on was a loose gas cap, if it's tightened, the light will quickly turn itself off. Again, if your catalytic converter is working correctly, 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 Tucson 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 Larry H. Miller Hyundai Peoria so the light and code can be double-checked and reset.
