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

When your check engine light comes on, this could be as simple as tightening or replacing your gas cap. Also, the check engine light could likewise be a warning of a significant 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 ordinarily means something less serious but a flashing check engine light indicates that your vehicle’s engine is in significant trouble and useful service is required promptly. If your check engine light is flashing in your Kia Rio, we remarkably recommend not to drive the vehicle and schedule Kia service today. Below is a list of the most common reasons your check engine light can come on:

  • The battery is low or dead. The battery in your Kia Rio 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 really require maintenance. The price of a new one depends on the type of Kia you drive, but check our current service coupons and specials.
  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your Kia Rio’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 Nalley Kia offers a free multi-point inspection with each Kia service. If you have an issue with your catalytic converter and don't get it repaired, your Kia Rio 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 delicate problems from overheating.
  • One of the most common and frequent cause is that your Kia Rio gas cap is loose, broken or missing. The gas cap for your Kia Rio 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 happens 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 expensive. Luckily, to replace a gas cap isn't costly. If your check engine light turns on rapidly after you put gas in your Kia Rio, 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.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak extreme havoc on your Kia Rio if it’s not installed accurately. These aftermarket components and accessories can drain the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound familiar, bring your Rio to Kia and have our team of gifted certified mechanics ensure that your aftermarket items were installed perfectly and aren't causing any issue. Getting accessories, particularly 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.
  • 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 vehicle will be less efficient when it comes to fuel economy. So what happens 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 Kia Rio's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the explicitly correct combination of air and fuel that enters the cylinders in your engine. A defective O2 sensor can still 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 Kia Rio 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 Kia Rio is having trouble starting, idling rough or has a sudden fast change in the position of the throttle pedal, this could be a important sign of a defective mass airflow sensor.
  • New Spark Plugs or Plug Wires are necessary for your Kia Rio. 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 experience 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 clogged catalytic converter or damage to ignition coils and O2 sensors, leading to more costly repairs.
  • Your Kia Rio has a vacuum leak. Each Kia Rio has a vacuum system that performs a wide variety of functions. The vacuum system still 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.

If you’re like most Kia owners, your heart sinks extremely because you may have definitely idea about what that light is trying to tell you or how you should react.

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 immediately 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 Kia auto repair mechanics at Nalley Kia. There are again a number of relatively inexpensive code readers that are designed for do-it-yourselfers, should you pick 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 precisely correct issue and repair it.
