A catalytic converter is a car component that works to reduce vehicle emissions and pollution. It is a metal canister installed in the exhaust system. It is filled with a chemical catalyst, usually a platinum and palladium mixture, and helps to convert the vehicle’s emissions into non-harmful gasses. Usually, a faulty catalytic converter will produce one of 5 symptoms that alert the driver that replacement may be required.

1. Reduced Engine Performance



One of the first symptoms commonly associated with a bad or failing catalytic converter is a reduction in engine performance. The catalytic converter is built into the vehicle’s exhaust system, and as a result, can affect the performance of the engine if it develops any problems. A clogged converter will restrict exhaust flow, while a cracked one will leak harmful gas. Either fault can negatively affect engine performance and cause reduction in power and acceleration as well as fuel economy.

2. Rattling Noise

Ratting noises from under the vehicle are another symptom of a bad or failing catalytic converter. If a catalytic converter becomes old or damaged internally from excessively rich fuel mixtures, the catalyst coated honeycomb meshes on the inside of the converter can collapse or break apart, causing a rattle. The rattle may be more obvious when starting the vehicle and will worsen over time.
