What Are The Symptoms Of A Failing Catalytic Converter

The catalytic converter makes up a large chunk of the automobiles emissions system. It is the component in charge of transforming toxic fumes into safer gasses before emitting them into the air. Catalytic converters help make driving a vehicle safer by reducing its environmental impact.

The component has its name because it uses a chemical catalyst to change the composition of the harmful combustion byproducts. Catalytic converters have changed driving throughout the world. When this part breaks or stops working in your car, it can be detrimental to your health and others as well.

What Are the Symptoms of a Failing Catalytic Converter?
  • Rattling sounds - A catalytic converter can get pretty noisy when it breaks apart on the inside. If you hear this sound from under your car, please have your catalytic converter inspected.
  • Rotten egg smell - This foul smell is a huge red flag that your emissions system needs repairs. It indicates that the converter cannot change the sulfur gases but instead lets it linger.
  • Check engine light illuminated - Your vehicles computer will detect the change of gasses before you can, which is why the check engine light is most likely going to pop up on your dash.
  • Loss in engine performance - You may notice a drop in fuel efficiency and loss in engine power due to the clog of gasses.
  • Failing to pass emissions test - Last but not least, a failure of an emissions test usually means something is wrong with the system, including the catalytic converter.
