Do I Need New Catalytic Converters?

Catalytic converters are part of your vehicle’s exhaust system, and when they fail, they can be very expensive to replace, due to the rare earth metals inside of them. They are a part of the vehicle emission system that improves efficiency and decreases your vehicle’s environmental impact. Over time, they can become clogged, leading to several issues and even a potential risk for fire. Learn the signs of bad catalytic converters to stay safe and keep your vehicle running it’s best.

Check Engine Light

This is one of the most obvious signs that something is wrong with your vehicle, and it can tell you if your catalytic converters are bad. The computer will sense that something is wrong with the catalytic converters or the O2 sensors (which are usually on either side of a catalytic converter) and trigger the light.

Your Car Feels Slower

When your catalytic converters get plugged up, they reduce engine performance. Exhaust gasses need to flow from your engine freely, and when they don’t, the result is sluggish performance. 

Reduced MPG

The O2 sensors on either side of the catalytic converters send important information to the vehicle’s computer collected from the exhaust gasses. Plugged catalytic converters can cause inaccurate readings from the O2 sensors, which will trigger the engine to burn more fuel.

Bad Smell from Your Exhaust

The main function of the catalytic converters is to convert the exhaust gas from your engine to a safer gas. Malfunctioning catalytic converters can’t do this properly, leading to a pungent odor that usually smells like rotten eggs or sulfur. It’s most noticeable when at wide-open throttle or going uphill. If you notice this smell, it’s important to address the issue quickly, as it can damage your engine or even lead to a fire in your exhaust.

Bad catalytic converters are common as your vehicle ages.
