Description
Three way catalytic converter (TWC) used to convert hydrocarbons (NS), carbon monoxide (CO) and nitrogen oxides (NOx) in exhaust gases into carbon dioxide (CO2), nitrogen (N2) and water vapor.
Inspection
If you suspect excessive back pressure (blockage) in the exhaust system, remove the converter from the vehicle and visually check for clogging, melting or cracking of the converter. Replace the neutralizer if any visually inspectable parts are damaged or obstructed.
