What Is a Catalytic Converter?
Essential for Emissions. Crucial for Performance.
A catalytic converter (often referred to as a CAT) is a critical component in your vehicle’s exhaust emissions system. Its job is to reduce harmful pollutants in exhaust gases before they’re released into the atmosphere.
Its Purpose:
A catalytic converter transforms toxic gases such as:
This chemical process is called catalysis.
How Does a Catalytic Converter Work?
Though it may resemble a muffler from the outside, the catalytic converter is a highly engineered component made with precious metals like:
Inside, it contains a honeycomb structure coated with these materials, which facilitate chemical reactions at high temperatures (400°C / 750°F and above). Here’s how it works:
The result? Cleaner emissions that meet environmental standards and help reduce smog and pollution.
How Long Does It Last?
Most catalytic converters are built to last around 100,000 miles or 10+ years, provided the engine is properly maintained.
However, several conditions can significantly reduce its lifespan, such as:
Unburned fuel can overheat the CAT, potentially melting the internal structure and leading to failure.
Symptoms of a Failing Catalytic Converter
A bad catalytic converter can be tricky to diagnose, as symptoms often mimic other engine issues. Common signs include:
In some cases, a catalytic converter cleaner might help restore function temporarily, but most clogged or damaged units will need replacement.

6 Symptoms of a Bad Catalytic Converter
Knowing the Signs Before It Becomes a Bigger Problem
The catalytic converter plays a vital role in your vehicle’s emissions system by reducing harmful gases. When it starts to fail, it can affect engine performance, fuel efficiency, and even your ability to pass an emissions test. Here are six common symptoms that may indicate your catalytic converter is going bad:
Check Engine Light (CEL)
Because of its importance in the exhaust system, a failing catalytic converter will often trigger the Check Engine Light. Most modern vehicles have multiple trouble codes (DTCs) directly tied to CAT efficiency. If you see the CEL flash shortly after driving, it’s time to get a diagnostic scan.
Engine Hesitation During Acceleration
A clogged or damaged catalytic converter restricts the flow of exhaust gases, creating backpressure that affects engine performance. This is often felt as hesitation or sluggishness when you try to accelerate, especially during highway merging or climbing hills.
Engine Misfires
When the converter can’t handle the exhaust flow, it can cause misfires—where one or more cylinders fail to fire properly. Misfires not only reduce power but can also lead to further damage to the ignition and exhaust systems.
Increased Emissions
A worn-out or inefficient catalytic converter won’t properly convert harmful gases like hydrocarbons, carbon monoxide, and nitrogen oxides, resulting in higher emissions. This can cause your vehicle to fail a smog or emissions test, especially in states with strict environmental regulations.
Possible Engine Overheating
In extreme cases, a severely clogged catalytic converter can cause the exhaust system to overheat. This buildup of pressure and heat may lead to the converter glowing red hot—and could even damage nearby components. If ignored, it could result in engine overheating or failure.
Strong Smell from Exhaust (Gas or Rotten Eggs)
If unburned fuel is reaching the exhaust due to poor combustion, you may notice a strong gasoline smell. As the catalytic converter degrades, it can also emit a rotten egg or sulfur-like odor—a sign that it’s failing to properly burn off hydrocarbon particles.
Need a Diagnosis? Nav Auto1 Can Help
If you’re experiencing any of these symptoms, don’t wait—ignoring catalytic converter issues can lead to costly repairs and poor vehicle performance. At Nav Auto1, our ASE-certified technicians can diagnose your emissions system using state-of-the-art tools and provide the best solution, whether it’s cleaning, repair, or full replacement.
