Your Vehicles catalytic converter is a emissions device that converts toxic gases and vehicle emissions in exhaust gases into less-toxic cleaner pollutant. This is done by catalyzing a redox reaction (an oxidation and a reduction reaction). Catalytic converters are used by all in the state of California on any gas vehicle 1971 and newer, and any Diesel vehicle 2001 and newer.

Aftermarket catalytic converters must be exempted from California’s anti-tampering laws. Many people turn to online or try to find a new or used Catalytic converter. You may not do either legally. All converters in the state of California are only allowed to be sold new. People here in Chico have called me tons of times asking us for used converters. Also you Catalytic converter must be California legal. This means that federal converters can not be installed on California cars. Also you can not have cat deletes, x-pipe or anything else of that nature.

Each time you take your vehicle in for a smog, the smog station checks the serial numbers on your catalytic converter. They make sure you have the correct and legal cat on your vehicle, also make sure you have a functioning oxygen sensor. The smog shop that you chose will be inspecting your vehicle with a fine tooth comb, making sure your catalytic converter, smog equipment, 02 sensor and drivability monitors are complete prior to the smog test! Make sure you do not have a check engine light on before you smog test. Also do not try resetting your engine code and run to the smog station. You will fail for incomplete self checks.

Do you have a P code? Is it p0420? Maybe its p0430? Either one of these codes could be for your catalytic converter or a faulty reading from a rear oxygen sensor. It is important that a shop checks your oxygen sensors and verify they are working before replacing your converter! Sometimes you get lucky and only need a oxygen sensor. Sometimes you need both oxygen sensors and your cat converter replaced. A diagnosis can save you big bucks if you are willing to have one done.

Is you check engine light on ? Is your vehicle sluggish to move? Will it not staying running anymore? A clogged catalytic converter can cause all sorts of headaches. Personally I have been down this path. My Dodge Neon a few years back would not go over 20 MPH. I had no codes and no clues. After performing a pressure test, (in which you remove the oxygen sensor and screw in a gauge and check for back pressure PSI) I found My cat was partially melted. Sometimes something that was designed to save us from our own pollution can fail, or in this case clog and keep you vehicle from running.

Your converter woes can put a dent in your pocket book. Each Californian has to deal with this headache in order to breath clean air and operate vehicles down the road legally. In the end its the price of living in a busy, over crowed state.
