When the catalytic converter works correctly, you won’t notice its presence. When the cat starts to fail, it definitely makes itself known. The most common sign of a problem with your catalytic converter is the noxious smell of rotten eggs.
Troubleshooting Catalytic Converters
If you have an emissions test performed, you will learn exactly which part of the catalytic converter has failed. Your technician can also perform an analysis of the exhaust gases to identify the fail point. In most cases, the failure results from a thick layer of contaminants on the walls or clogs in your catalytic converter.
Catalytic Converter Replacement
If the cat is indeed failing you will need to have it replaced at that point to restore your vehicle’s low emission status and overall performance. In addition to an increase in harmful emissions, continuing to drive with a faulty cat can result in a loss of power, especially during initial acceleration.
Selecting a Catalytic Converter
Unfortunately, you cannot have your catalytic converter replaced with a used unit to save money. The sale of used cats is against the law due to the strict regulations surrounding emission control systems. Luckily, you can have your technician source a new catalytic converter within a short time period to quickly return your car to the road.
