If you’re an owner of Kia, probably you may have heard about problems with the catalytic converter. The catalytic converter makes sure that all those harmful emissions coming from your car get reduced to a minimum so your car can meet environmental standards. Like any other component, it may break down after some time and result in engine problems with higher emissions. In this article, we’ll be discussing everything you need to know about Kia catalytic converter fixes, from diagnosis to the most common causes and possible solutions.
Introduction to Kia Catalytic Converter Problems
The catalytic converter in your Kia was designed to transform noxious gases into less noxious emissions before they leave your exhaust system. Some common symptoms when this component fails include loss of fuel efficiency and illumination of the engine light, among many others. Most models, such as Kia Optima, Sorento, and Sportage, may gradually experience some catalytic converter issues with time.
The most common DTCs concerning catalytic converter malfunction are represented by code P0420. This is going to be the code that says your catalytic converter is not acting efficiently, failing to convert the harmful exhaust gases as it needs to. Below, we will discuss catalytic converter failure diagnosis and replacement on your Kia model and ways you can prevent this from becoming a much more expensive fix.
Whether it is actually the P0420 error code that you will face, or even other problems inhibiting performance, knowing how the catalytic converter works, what causes it to fail, and how to fix it will go a long way in helping to resolve the issue. After obtaining guidelines and testing tips from this article, you will go further in taking proper care of your Kia whenever its catalytic converter is at fault, so it once again can give great running performance while meeting the emissions standard.
What Causes Catalytic Converter Failure in Kia Vehicles?
Catalytic converter issues are rather common for Kia models, especially those which have been on the road for several years. The catalytic converter normally fails due to issues revolving around:
- Contaminants: The catalytic converter in your Kia will eventually become clogged or contaminated due to engine oil, coolant, or too much unburned fuel over a long period. These contaminants reduce the efficiency of the converter, leading to eventual failure.
- Excessive Heat: The catalytic converter works at extremely high temperatures; overheating can cause deterioration of the internal components. In most cases, this is a result of engine misfires, excessively lean mixtures, or malfunctioning oxygen sensors.
- Wear and Age: While catalytic converters are designed tough, it does not mean that they would last forever. As your Kia piles on the mileage, the catalytic converter can wear out naturally and stop doing its job well in emission control.
- Engine Performance Problems: Engine problems, such as malfunctioned fuel injectors or a faulty ignition system, can cause unburned fuel to make its way into the exhaust system, overwhelming the function of the catalytic converter, thereby causing it to fail.
Catalytic Converter Diagnosis in Kias
The diagnosis should be the first thing one should undertake when trying to fix his or her Kia’s catalytic converter. Following are some of the common symptoms one may encounter due to a failing catalytic converter:
Engine Light is Probably the most noticeable signs of an issue with the catalytic converter, which is the “Check Engine” lights that should the light come on, and your vehicle logs a P0420 code, it is an indication that the converter is not functioning efficiently.
Bad Performance of the Engine is the other sign; The malfunction of the catalytic converter will make the flow of air restricted, which will make the performance of the engine very sluggish. One may feel that the acceleration is not proper, or it may stall, or there might even be failure to start the engine.
Sometimes it occurs when you are spending too much at the pump, then it might be your catalytic converter that is not working efficiently. Most times, this happens with a clogged converter, as it does not allow the smooth flow of exhaust gases.
When the exhaust gives off a smell of sulfur or rotten eggs, it signals a problem with the catalytic converter. This is because, in failure, the converter is unable to burn off hydrogen sulfide anymore.

How to Fix Kia Catalytic Converter Problems
Fixing a catalytic converter issue in a Kia can be as easy or as complicated, depending on what the problem is. Here are general steps you could go through in order to fix the issue:
- Step 1: Scan for Trouble Codes First of all, you should take an OBD-II scanner to scan for trouble codes. The most common code one would find when the catalytic converter goes bad is the P0420 code. After that, you can proceed with further checks if that’s the code shown.
- Step 2: Check the Exhaust System Inspect the exhaust system of your Kia for any physical damage; this includes leaks or cracks in the system, which may be acting as the feeding cause of improper oxygen sensor reading.
- Step 3: Check Oxygen Sensors: The catalytic converter issues could be related to the oxygen sensors. Your Kia has upstream and downstream oxygen sensors. These sensors measure the level of exhaust gases and send a signal to the vehicle’s onboard computer. If the signals from the sensors are incorrect, this may cause overheating in the catalytic converter. You will need to check these sensors using a multimeter to verify whether they are working or not.
- Step 4: Temperature Check This is one of the simplest methods to check if your catalytic converter is functional or not. Once the motor heats up, take a reading on the exhaust temperature both before and after the converter. A good operating converter will show an increase in temperature by at least 100 degrees Fahrenheit. If this does not occur, there might be some blockage in the converter that calls for its replacement.
- Step 5: Catalytic Converter Replacement-If the converter happens to be seriously clogged or damaged, it will need replacement. While this can be a somewhat expensive repair, it is an important one for the restoration of your vehicle’s emissions control system. Consult your Kia service manual for the proper replacement procedure or have the replacement done professionally by a qualified mechanic.
Prevention Measures Against Catalytic Converter Failure in Your Kia
Although some catalytic converter failures cannot be totally avoided, a few things can be done to extend the life of the catalytic converter and prevent untimely wear:
Routine Maintenance: Properly maintain your Kia through routine oil changes, replacing spark plugs, and cleaning fuel injectors. These steps keep contaminants out of the catalytic converter.
Do Not Delay in Fixing Engine Problems: Immediately attend to any engine misfires, fuel system issues, or oxygen sensor faults; these will make unburned fuel or oil enter the converter and cause overheating or contamination.
Use High-Quality Fuel: The proper octane rating for your Kia can help you avoid fuel system problems that may affect the catalytic converter.
If you have tried the troubleshooting steps described above and the problem persists, then perhaps it is time you called in the professionals. Many a time, it is not the converter itself that causes a problem; rather, something else needs to be fixed. This could be anything from problems related to the cracked exhaust manifold, leaks of the exhaust system, or even problems with the ECM. A mechanic will do a more detailed diagnostic test to determine the exact cause of the problem.
Cost of Replacing Catalytic Converter for Kia
To say the truth, it can be rather expensive to replace the catalytic converter in case your Kia is out of warranty. The replacement cost may vary for different models from $800 to more than $2,500 including labor. Still, driving with a faulty converter is not only harmful for your engine but also illegal due to ecological laws taken in many areas.
