A failing catalytic converter is a nightmare for any car owner. But how can you tell if yours is going bad? This article covers everything you need to know about catalytic converter problems, from symptoms and causes to costs and helpful tips.
What is a Catalytic Converter and How Does it Work?
The catalytic converter, or “cat” for short, is a crucial part of your car’s exhaust system. Located in the exhaust pipe, it converts harmful pollutants into less harmful substances before they are released into the environment.
Damaged Catalytic Converter Symptoms
Symptoms of a Failing Catalytic Converter
A faulty catalytic converter often manifests itself through various symptoms. Look out for the following signs:
- Loss of Power: The engine has less power than usual.
- Hesitation or Stuttering During Acceleration: The car accelerates unevenly and jerkily.
- Unusual Noises: Knocking or rattling sounds can be heard from the catalytic converter area.
- Check Engine Light Illumination: The check engine light on the dashboard illuminates.
- Increased Fuel Consumption: The car consumes more fuel than usual.
- Rotten Egg Smell: An unpleasant sulfurous (rotten egg) smell emanates from the exhaust.
“A defective catalytic converter can have serious consequences for the environment and public health,” warns Dr. Ing. Markus Schmidt, exhaust specialist at the Technical University of Munich. “Therefore, it’s crucial to recognize the symptoms early and address the problem as quickly as possible.”
Causes of a Failing Catalytic Converter
A catalytic converter can fail for various reasons. Common causes include:
- High Engine Oil Consumption: If the engine burns too much oil, it can damage the catalytic converter.
- Faulty Spark Plugs or Ignition Coils: Misfiring spark plugs can cause unburned fuel to enter the catalytic converter, damaging it.
- Physical Damage: An external impact, such as from hitting a curb, can damage the catalytic converter.
- Wear and Tear: Catalytic converters are subject to natural wear and tear and need to be replaced after a certain mileage.
