5 Symptoms of a Failing Catalytic Converter

A catalytic converter is an integral part of the automobile's exhaust system. It reduces vehicle emissions and pollution by burning harmful engine byproducts and converting them into breathable gasses. Though catalytic converters are made to last the life of your vehicle, they can become clogged, broken, or even stolen. When your catalytic converter stops working or goes missing, your car will likely show one (or more) of the following warning signs.

Decrease in Engine Performance

Since the catalytic converter is a vital part of the vehicle's exhaust system, it can negatively impact engine performance. If the converter is jammed, it will limit the flow of the exhaust. But, if the catalytic converter is leaking, it could potentially circulate harmful gas. Both clogged and punctured converters can diminish engine performance and decrease your car's acceleration capacity.

A Rotten Egg or Sulfur Smell

A proper functioning catalytic converter can transform hydrogen sulfide from combustion into sulfur dioxide. When the converter isn't working, it may give off a smelly stench as it can't correctly convert the fumes. Furthermore, you may also see dark smoke accompanying the rotten-egg smell.

Check Engine Light On Dashboard

The check engine light may come on for various reasons, including a faulty catalytic converter. Once the sensors detect a deficiency in the gas levels in your exhaust, it will signal you for help.

Rattling Noise

The parts inside your exhaust can break down over time, causing a rattling sound within your converter. If you hear a disturbance coming from under the vehicle, it may very well be your catalytic converter. You may notice the sound worsening over time.e

Failed Smog Test

Your state may require your car to pass an emissions test successfully. If your vehicle has a flawed catalytic converter, it will not pass the test.

 

Ensuring your catalytic converter is operational is essential to your safety, the environment, and the overall well-being of your vehicle. If you need a catalytic converter repair or replacement, please give Carport Automotive a call or visit today!
