What Is a Catalytic Converter?
Your catalytic converter is the heart of your vehicle's emissions system. It transforms harmful gases like carbon monoxide and nitrogen oxides into less harmful emissions before they exit your tailpipe.
When a catalytic converter fails, you might notice a sulfur smell (like rotten eggs), reduced engine performance, a glowing converter, or your check engine light coming on. Left untreated, a failing converter can lead to bigger engine problems and failed state emissions tests.
Tennessee's emissions testing requirements in Davidson and surrounding counties make a functioning converter essential. We can diagnose issues, recommend solutions, and get you back on the road—fast.
Schedule DiagnosisSigns of Converter Trouble
Don't ignore these warning signs. Early diagnosis can save you money and prevent more serious issues.
Check Engine Light
Your CEL often comes on when the converter is struggling. We use advanced diagnostics to read the specific error code and identify the exact problem.
Sulfur Smell
A strong rotten egg smell from your exhaust usually means the converter isn't properly processing fuel byproducts. This is a clear sign of trouble.
Poor Performance
A clogged converter restricts exhaust flow, causing sluggish acceleration, reduced power, and difficulty maintaining speed.
Glowing Converter
If your converter glows red hot when driving, it's a serious problem indicating a complete blockage. This needs immediate attention.
Failed Emissions Test
Tennessee emissions tests check for excessive hydrocarbons and carbon monoxide. A failing converter will cause an immediate fail.
Rattling Sound
Internal damage to the converter's catalyst material can cause rattling, especially when the vehicle is idling or decelerating.
