Typically, this happens in older cars when the catalytic converter becomes clogged. Over time, your car can also use all the metals that act as the catalysts in the converter, which can cause the converter to fail. How do you know if your catalytic converter needs to be repaired or replaced? Here are five common symptoms of a bad or failing catalytic converter. The catalytic converter is your car's main component responsible for controlling engine emissions.
An increase in the level of carbon emissions coming from your exhaust is a common sign that your catalytic converter may be failing. This can be from things like antifreeze or motor oil contaminating the chemical mechanisms inside the catalytic converter. Your on-board diagnostic system — which comes standard in all cars and trucks manufactured since — tests the catalytic converter automatically.
Oxygen and air-to-fuel ratio sensors monitor the efficiency of the catalytic converter by monitoring the gas levels in your exhaust. If too much pollution is coming out of your tailpipe, your check engine light will come on. A clogged cat makes it more difficult for exhaust to exit your vehicle, so it builds up and is thicker and darker when it comes out. Experiencing pain at the pump?
That, combined with other symptoms, could point to a catalytic converter failure. A clogged cat causes reduced airflow that causes your engine to burn extra fuel. Not only does this increase your fuel bill and waste gas, it makes the clog worse. To the average driver, lower fuel efficiency is one of the most noticeable symptoms of a bad catalytic converter.
Your vehicle is misfiring. Catalytic converter problems cause gas within your engine to heat up to the point that it actually ignites. This ignition is what causes the misfiring sensation — and that can destroy engine components. Anytime your vehicle misfires, you should have it checked out by a reputable service professional.
You remove oxygen sensors and vehicle performance plummets. If you happen to know your way around under the hood or better yet you know a great mechanic you can run a test. Allotted Licenses. Remaining Licenses. Remember me. Forgot your password? Select a new vehicle.

A Bad Catalytic Converter Can Burn Through Overtime The inner fiber of your catalytic converter may be burned through if the car engine is running or burning oil too much.
Catalytic Converters. A catalyst is the substance that accelerates a chemical reaction, and within the catalytic converter itself, are two types of catalysts. The first is a reduction catalyst, which uses platinum and rhodium to reduce the nitrous oxide emissions. Nitrous oxide is produced by nitrogen oxide and nitrogen dioxide within the exhaust gasses from your internal combustion engine. Without getting rid of these gasses, your bad catalytic converter can ruin your engine.
The second catalyst type in your catalytic converter is the oxidation catalyst, using platinum and palladium to complete the job of the catalytic converter. These catalysts burn the carbon monoxide and hydrocarbons that are still located in the incoming gas, helping to get rid of the smog produced by the unburnt fuel.
Without this step, the bad catalytic converter can ruin your engine. The final stage of the emission control process of the catalytic converter mechanism is the o2 sensor that is just higher up than the catalytic converter. This sensor relays information back to the electronic control unit about how much oxygen is within the exhaust gases, with the on-board computer adjusting the air and fuel mixture accordingly.
If your catalytic converter is damaged and cannot complete these cleaning processes, then your converter is failing,and a bad catalytic converter can ruin your engine. As we know now, your catalytic converter is a huge part of your vehicle. This is key to the longevity and the lifespan of your car and the overall inner workings of your vehicle, by neutralizing hazardous compounds in your exhaust system, like carbon monoxide.
By doing so, this catalytic converter can cause a huge increase in gas mileage and performance. Catalytic converters are made to last the entire lifetime of your car, but without maintenance and regular maintenance, these repair issues in the other components of the inside of your car and the exhaust system can cause wear and tear, highlighting damage over time.
Driving with a failing or bad catalytic converter can damage your car further, hurt the environment due to poor emissions, reduce your overall fuel mileage, and damage other components of your exhaust system.
Knowing that a bad catalytic converter can ruin your engine is crucial to keep you on top of the maintenance of your catalytic converter.
