What Does a Catalytic Converter Do? The catalytic converter is a key component of your vehicle’s exhaust and emissions system. It converts harmful pollutants from engine exhaust—including carbon monoxide, hydrocarbons, and nitrogen oxides—into less harmful gases before they exit the tailpipe.
A failing catalytic converter can lead to:
- Poor engine performance
- Decreased fuel efficiency
- Rattling noise from under the car
- Overheating or melted converter
- Failed emissions inspection
- Persistent Check Engine or Service Engine Soon light
Symptoms of a Bad Catalytic Converter
