A catalytic converter reduces pollutants in exhaust gas using a single-bed design and a three-way catalyst coated with platinum and rhodium. This reduces levels of nitrogen oxides, hydrocarbons, and carbon monoxide. If you suspect a malfunction, take your vehicle to a dealer or authorized facility for diagnosis and repair. Check the converter for leaks or damage when the vehicle is raised for servicing. If damaged, it should be replaced, requiring removal of the exhaust pipe assembly. This can be done at a dealer service department or muffler shop.
