yup, you're cat is starting to go out... it may not be totally dead yet, but if you're expecting on doing a smog test anytime soon, you might want to look into prices for a new one...

are you planning on doing a smog check anytime soon?

Simple! Just buy an ECU simulator for about $30 bucks and that <U>should</U> stop the CEL from coming on.

Re: ecu code 67. how to fix? (C_Civic)
is that an ecu simulator or an o2 simulator? a p0420 code is set when the secondary o2 sensor shows an oscillating voltage similar to the primary o2... it should be fairly steady.
you might be able to "fool" the ecu into thinking the cat is working right IF you're able to provide the ecu a constant 0.6v

Re: ecu code 67. how to fix? (taz77)
its a small chip that u put on your Ecu to trick it to believing that the secondary O2 sensor is even there....or its running fine...I've heard it works and i just ordered mine and will give it a try this weekend....check Ebay for it....i forgot the other web page!
