Common Signs of Catalytic Converter Repair


sA failing catalytic converter can lead to significant engine issues, poor performance, and higher emissions. Look out for these warning signs:

Check Engine Light: Illuminates when there’s an issue with the emissions control system.

Sluggish Acceleration: Reduced engine power and slower response when you press the gas.

Poor Fuel Economy: A drop in mileage could be linked to a clogged or failing converter.

Rotten Egg Smell: A strong sulfur odor coming from the exhaust indicates internal damage.

Rattling Noise: Loose or broken internal parts can cause a rattling sound under the vehicle.

Failed Emissions Test: If you can’t pass an emissions inspection, the catalytic converter might be the culprit.

Engine Misfires or Rough Idle: Poor fuel-to-air mixture or exhaust flow issues can cause engine trouble.

Overheating or Burnt Smell: An overheated catalytic converter may emit a burning smell and cause engine damage.

Common Causes of Catalytic Converter Failure


Understanding the root cause of catalytic converter failure helps prevent future issues. Some of the most common causes include:

Rich Fuel Mixture: Caused by faulty spark plugs or fuel injectors, this leads to excessive fuel entering the converter.

Leaking Engine Gaskets: Coolant or oil leaking into the exhaust system can clog the converter.

Malfunctioning Oxygen Sensors: These sensors regulate the air-fuel mixture. If they fail, they can cause the converter to overheat or become clogged.

Poor Engine Timing: Improper timing can lead to inefficient combustion, which damages the converter.

Physical Damage: Road debris or impacts can damage the converter, especially if the vehicle is driven on rough terrain.

Pro Tip: Our expert diagnostic service can pinpoint the exact cause of your catalytic converter issues, preventing unnecessary replacements.
