Signs of a Bad Catalytic Converter: What to Look For
A catalytic converter plays a crucial role in reducing harmful emissions by converting toxic gases into harmless substances. However, over time, it can become clogged and malfunction, affecting your vehicle’s performance and the environment. Here’s how to spot a problem early.
What Is a Catalytic Converter?
The catalytic converter helps reduce harmful emissions from your vehicle’s engine by converting toxic chemicals into less harmful substances. However, excessive buildup of gases can cause clogs, affecting its function and potentially damaging your engine.
Why Do Catalytic Converters Fail?
A buildup of exhaust gases and residue can clog the catalytic converter, preventing it from working properly. This leads to harmful pollutants being released into the air, potentially damaging the engine and causing costly repairs.
Symptoms of a Failing Catalytic Converter
- Dark Smoke from the Exhaust: Dark smoke indicates a buildup of gases inside the converter, leading to higher concentrations of toxic emissions.
- Illuminated Check Engine Light: If your engine light stays on, even after checking other common issues, the catalytic converter could be the cause.
- Decreased Fuel Economy: A clogged converter increases fuel consumption, reducing mileage and efficiency.
- Rotten Egg Smell: A sulfur smell from the exhaust could indicate the converter is no longer neutralizing harmful gases.
- Engine Misfires or Rattling: A malfunctioning converter can cause misfires and a rattling noise as its internal components break apart.
