P0420 code from check engine light 2000 Mazda Protege?
Got this code and it says something abt catalytic
converter system. God I hope not cause that's expensive to replace? Do cat system even wear out? Car has 140k on it and was bought new. |

I would "reset" the system and see if it comes back before I changed
anything. I had the CEL come on in my 2003 Miata for the : o11 and 012 code. "That", said that my ignition was too far advanced and too far retarted at the same time. Well, the 2003 has VVT and I had high reved it when the engine was not warmed up enough and the VVT hit the stops on high and low range of the VVT. I disconnected the battery for 3 tree min., Reset my radio stations and it all went away. We all know that computers "can't" make errors ! :-) Bruce Bing '03 LS |

It's also possible that the first O2 sensor is getting a bit long in the
tooth. Usually, the front sensor fails before the rear one. On my Miata, the front sensor had a slightly lower output and had a bit slower response than a good sensor. This caused the 420 code to set periodically. A reset might be OK for months, a week, or a day. I only spent about two years screwing around with this and that before I broke down and replaced the sensor. > wrote in message ... > Got this code and it says something abt catalytic > converter system.

Ok thanks..... should I go ahead and replace BOTH sensors if getting the job done by a mechanic? I'm unemployed and would MUCH rather replace a couple of sensors than a catalytic converter itself as I'm assuming a new converter is gonna cost abt $500 or more. yes? |

And, for whatever it's worth, sensors are designed to work for 80k or more,
I.E. 80-100k miles. A universal sensor (four lead, with splicer) is usually less than $100. > wrote in message ... > pws > wrote: > > >> Ok thanks..... should I go ahead and replace BOTH > >> sensors if getting the job done by a mechanic? > > > >It can't hurt, but it likely not needed, especially the rear one.
