Catalyic Converter
My 99 Honda Civic Ex 2dr check engine light came on and the error code
message was for my Catalyic Converter which I was told I need to replace. I was also told that I do not have to but I should replace my O2 sensors also just to make sure all is well. O2 sensors are expensive and if I do not have to replace it then I would not. I was wondering if anyone can tell me whether or not it is ok just to replace the Catalyic Converter without having to purchase new O2 sensors, even though the Computer Diagonistic only indicated a problem with my Catalyic Converter. My next statement and question is I called and Independent Muffler shop and basically asked how much it would cost to put on a new Converter, the guy at the Muffler shop asked me if my car runs fine, I said yes. He also asked if my sensor lights come on and off, I said no, I told him that I had the code erased from my car after using a Converter Cleaner to see it that would help but no sooner the check engine light came back on. He also told me that it is not really necessary to have my Converter changed because more than likely the check engine light will end up coming back on. He said some of the Manufacurers like Ford are trying to work on there error codes with regards to Converters because it comes on too much and that they are espensive parts to replace. If there is anyone that have any info with regards to this please let me know Thanks |

It is not necessary to replace the O2 sensor unless a code comes up. The
computer keeps close checks on them just as it does on the converter. The O2 sensors can also be checked on an OBDII tester with diagnostic ability, not the basic code readers. Mileage makes a difference as the converter should be covered for 80k miles. Check your warranty information. If over 100k then the converter probably needs changed. > wrote in message oups.com... > My 99 Honda Civic Ex 2dr check engine light came on and the error code > message was for my Catalyic Converter which I was told I need to > replace.

oups.com: > Yes my error code message read P0420 > Thanks > Did you see Busiu's post? That's the first mention I've heard of a cracked manifold causing this error. If it's common, there ought to be a TSB sooner or later outlining this. My experience with the P0420 error is that it's mostly city-driven cars that experience it, so it appears to be related to a cat that's contaminated from lots of low-speed driving. Based on that observation, I wrote this: http://www.tegger.com/hondafaq/p0420.html By the way, if you're in the US, there is an eight-year Federal emissions warranty covering the cat. If you're in the US, a new OEM cat will come to you at no charge. You may want to explore that first with your dealer. I'm going to add Busiu's experience to the FAQ. If Busiu has any other info to report, such as a TSB, I'd love to hear from him. -- TeGGeR® The Unofficial Honda/Acura FAQ www.tegger.com/hondafaq/ |

I'm unaware if an official TSB exists but my Honda mechanic tells me he sees this problem all the time. It's also the primary reason why you can't find an Exhaust Manifold for this generation of Civic at your local wreckers. The good ones have been pillaged and the remainder are cracked. |
