How Can I Check for a Restricted Catalytic Converter?

Because of a Federally mandated extended warranty which covers emissions-related components such as the catalytic converter, it is recommended to check with a dealer service department before replacing the converter at your own expense. The catalytic converter is an emission control device that reduces pollutants in the exhaust gas stream. There are two types of converters: the conventional oxidation catalyst and the three-way catalyst. If you suspect the converter is malfunctioning, take the vehicle to a dealer service department or authorized emissions inspection facility for diagnosis and repair. Additionally, it is important to regularly check the converter for leaks, corrosion, dents, and other damage when the vehicle is raised for servicing of underbody components. If damage is discovered, the converter should be replaced. While catalytic converters don't break often, they can become plugged. To check for a restricted converter, you can use a vacuum gauge to diagnose the effect of a blocked exhaust on intake vacuum. By following the steps of opening the throttle until the engine speed is about 2000 rpm and then releasing the throttle quickly, you can determine if there is a restriction. If the gauge doesn't show a significant increase in reading or seems to momentarily hover around its highest reading before returning, it indicates a plugged exhaust system or converter.
