When your engine is running, your 2005 Honda Civic catalytic converter creates a chemical reaction that neutralizes harmful compounds in the exhaust gases before they enter the atmosphere. If your car doesn't seem to be running quite right or it's failed a smog test, it's potentially an issue with the catalytic converter. Fortunately, it's an easily accessible part under your car and changing it is straightforward with parts available for your Civic at AutoZone.
How Do Catalytic Converters Work?
Every car since the late 1970s has been equipped with one or more catalytic converters as part of its
emission control and exhaust system. This device looks like a small muffler and is fitted inline in the exhaust pipe. Inside the metal housing is a structure that resembles honeycomb with trace amounts of precious metals like palladium, rhodium, and platinum embedded into it. They're the catalyst material.
When exhaust gas containing hydrocarbons and other pollutants meet the catalyst material, they react and superheat, breaking them down into harmless compounds before they exit the tailpipe.
Symptoms of a Failing Catalytic Converter
Although they're designed to last for hundreds of thousands of miles, parts like the 2005 Honda Civic 1.7 catalytic converter can fail from overheating, contamination, poor fuel, or even impact with road debris. When it fails, symptoms are usually evident ahead of time. They can include an odor like rotten eggs, rough running, rattle under the car on acceleration or at idle, and it's almost guaranteed the Check Engine light will illuminate. It won't pass a smog check either.
2005 Honda Civic Catalytic Converter Replacement Cost
The solution for a failed catalytic converter is to replace it.
Catalytic converter parts are often welded into place and require specialized equipment, but sometimes exhaust clamps can be used to fasten it instead. Parts range in price from around $200 to $1,400 depending on your vehicle build.
