The catalytic converter in your Honda converts dangerous gases produced by the engine into less toxic ones. Changing these gases before they leave the engine reduces air pollution. The converter is a very tough component, but it is subject to wear or damage. Your Honda dealer can fix any converter problem, and these are some of the issues a converter could face.

Signs You Need To Get a New Catalytic Converter at Your Honda Dealer

Check Engine Light

Your Honda has numerous sensors inside it, and each sensor monitors a specific component. The computer in your car is connected to each sensor and continuously receives information about their connected components and systems. If a sensor detects any issue with its component, this information is sent to the computer, and the relevant warning light on your dash will illuminate.
The check engine light notifies you of any problem that affects your engine. If your converter is blocked or failing, this impacts the engine. A blocked converter, for example, will cause engine gases to build up in the engine instead of being expelled through the tailpipe. The increasing pressure from these gases will trigger the warning light. We’ll examine your converter for the source of the problem and then repair it.

Rattling Nosies Underneath Your Car

Strange rattling noises are always a reason to worry, particularly because your Honda is almost completely silent when moving. These rattling noises could mean one of the brackets that supports your exhaust is loose, or your converter could be damaged. There are other possible causes for the noise, but these two are the most common.
The converter has a honeycomb inner structure that provides the surface area for gas conversion. Excessive heat in the converter due to damaged engine components can cause part of the inner structure to crack. Any crack will expand as time passes, and pieces of the honeycomb can break off. These pieces will move around inside the converter as you drive. If this is the problem, we’ll need to replace your converter.

Rotten Egg Smell

Hydrogen sulfide is a toxic chemical produced during the combustion process. It’s also noteworthy for its foul smell that resembles rotten eggs. When your converter is working effectively, this chemical is converted into sulfur dioxide, which is harmless. If you smell a rotten egg smell from the exhaust, your converter is failing.

Age or damage can cause the converter to stop changing gases before they exit the exhaust. Our technicians will need to examine the converter to discover why it failed. We’ll repair the damage if possible, or replace it if it’s several damaged.
