Acura 18290-RYE-A00 Rear Primary Converter

Pollutants in exhaust gas can be lessened by a catalytic converter. Oxidation converters and reduction converters are the two main types of converters. There is need for specialized equipment to check for problems and this should be done by a professional. A vacuum gauge can be used to test for a clogged converter. To change on certain models of Acura and Honda, lift up the vehicle, unplug the oxygen sensor, take off retaining nuts, and replace corroded fasteners.

Oxidation converters use a ceramic honeycomb substrate coated with platinum and palladium to reduce unburned hydrocarbons and carbon monoxide by adding oxygen to the exhaust stream, converting them to water vapor and carbon dioxide.
