Hyundai Tucson Check Engine Light Codes

The check engine light turning on can be quite intimidating to see that little light on your vehicle’s dashboard suddenly illuminates, but in reality, it is not something that should cause you to shut down in fear right away. If you hear the term, diagnostic trouble codes (DTC), these are just another name for check engine light codes. These are automotive computer codes stored by the ECM, also known as the OBD (on-board computer diagnostic system) in your Tucson. There are hundreds of different codes that your check engine light can represent. While that sounds daunting, with a little patience, tackling basic diagnostics will give you useful knowledge about your vehicle and will also allow that Check Engine Light to do what it is really supposed to do: be your guide. Unfortunately, obvious and helpful vehicle symptoms do not always accompany an illuminated Check Engine Light. Since there are hundreds of possible OBD codes, there are also hundreds of possible reasons for the light, including:

  • Bad Spark Plugs
  • Emissions controls issues
  • Computer output circuit issues
  • Transmission issues
  • Loose Gas Cap or Missing Gas Cap
  • Ignition system faults
  • Old Battery
  • Fuel and air metering systems problems
  • O2 Sensor
This is why it is important for someone who does not have a lot of automotive knowledge to not assume what a code means.

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 turn itself off. Likewise, if your catalytic converter is going functional, 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 Nalley Hyundai so the light and code can be double-checked and reset.

What do you do when you’re driving along in your Hyundai Tucson and suddenly, a yellow light illuminates on your dash and says "Check Engine". If you’re like most Hyundai owners, your heart sinks a little because you have little 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 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 recommended that you get your Hyundai Tucson checked as soon as possible. Ignoring that warning could end up causing major damage to expensive engine components.

When your Hyundai Tucson'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 identifies as 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 Nalley Hyundai. 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 issue and repair it.

When your check engine light comes on, this could be as simple as tightening or replacing your gas cap. Likewise, 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 repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady glow typically means something less serious but a flashing check engine light indicates that your vehicle’s engine is in serious trouble and service is needed immediately. If your check engine light is flashing in your Hyundai Tucson, 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:

  • Issues with all aftermarket items. An aftermarket alarm, exhaust or contrasting item can wreak 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 impede the car from starting. If these issues sound practical, bring your Tucson to Hyundai and have our team of certified mechanics ensure that your aftermarket items were installed correctly and aren't causing all issue. Getting accessories, especially aftermarket parts and accessories, or using OEM parts able place might cost a miniscule bit more but could save you money from having to get poor work and wear and tear caused by poor installation work corrected.
  • One of the most regular and countless cause is that your Hyundai Tucson gas cap is loose, damaged or missing. The gas cap for your Hyundai Tucson 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 bad fuel cap? If your gas cap is common 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 fancy. If your check engine light turns on quickly after you put gas in your Hyundai Tucson, able thing you should check is to make satisfied the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
  • 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 wear and tear to your catalytic converter and your Hyundai Tucson's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to learn the proper mixture of air and fuel that enters the cylinders in your engine. A bad O2 sensor can also cause a car to fail an emissions test.
  • Your Hyundai Tucson has a vacuum leak. Every Hyundai Tucson has a vacuum system that performs a wide mixture of functions. The vacuum system also helps decrease 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 arid out and crack, especially if they’re exposed to intense heat or extreme fussy.
  • The battery is low or dead. The battery in you Hyundai Tucson every necessary. 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 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 existing service coupons and specials.
  • 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 basic to run your engine efficiently by measuring the fee of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to certain changes, same altitude. If your Hyundai Tucson is having trouble starting, idling rough or has a immediate change in the position of the throttle pedal, this could be a sign of a bad mass airflow sensor.
  • 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 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 Hyundai Tucson 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 contrasting problems from overheating.
  • New Spark Plugs or Plug Wires are basic for your Hyundai Tucson. 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. The spark plug wires deliver the spark from the ignition coil to the spark plugs. If you're spark plugs or spark plug wires are bad or common, 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 wear and tear to ignition coils and O2 sensors, cut down to more fancy repairs.
  • Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, practical as the O2 sensor, measures the fee of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your car will be less agreeable when it comes to fuel economy.
