Top Signs Your Catalytic Converter May Be Failing

Catalytic converters are an essential part of every vehicle's exhaust system, significantly reducing harmful emissions and playing a vital role in protecting the environment. However, wear and tear, age, or damage can lead to the need for repair or replacement.

What is the Role of a Catalytic Converter?

The job of a catalytic converter is to transform toxic gases produced during combustion, such as carbon monoxide, hydrocarbons, and nitrogen oxides—into less harmful substances before they enter the atmosphere. For example, a properly functioning catalytic converter can reduce carbon monoxide emissions by over 90%. Understanding how this function works emphasizes the importance of maintaining this component for both vehicle efficiency and adherence to environmental regulations.

• Check Engine Light: This warning light can signal various problems, including catalytic converter issues. Mechanics estimate that about 20% of check engine light issues are linked to catalytic converters.
