Your catalytic converter significantly reduces your engine’s toxic emissions and pollutants. Keeping it in working order means cleaner air and a better running vehicle.
Diagnostic Trouble Codes
One of the most important components of your exhaust system is the catalytic converter. We’ve all heard of it, many of us have had to replace one, but many people have no idea what it does. Put simply, the catalytic converter, commonly called a cat, converts some of the more dangerous substances in your engine exhaust into safer emissions. The process uses a catalyst to initiate a chemical reaction in the combustion emissions. Most models used today are called three-way converters because they convert the three most abundant pollutants into less toxic substances. Carbon Monoxide and excess Hydrocarbons are oxidized to create carbon dioxide and water, and nitrogen oxides undergo a reduction reaction to produce nitrogen.
Don’t ignore the check engine light. Catalytic converter damage, if left unchecked, may warrant replacement, setting you back $1000 dollars or more. At Master Muffler we encourage early catalytic converter repair and diagnostic. If your catalytic converter is in need of repair we will see one or more of the following codes:
P0420 | Catalyst system efficiency below threshold (bank 1) |
P0430 | Catalyst system efficiency below threshold (bank 2) |
P0300 | Random/multiple cylinder misfire detected |
P0301 | Cylinder 1 misfire detected |
P0302 | Cylinder 2 misfire detected |
P0303 | Cylinder 3 misfire detected |
P0304 | Cylinder 4 misfire detected |
P0128 | Coolant thermostat (coolan temp bleow thermostat regulating temperature) |
P0171 | System too lean (bank 1) |
P0174 | System too lean (bank 2) |
P0401 | Exhaust gas recirculation flow insufficient detected |
P0455 | Evaporative emission control system leak detected (large leak) |
