My Check Engine Light came on yesterday so i ran a test on it.
0702 and 0703 popped up. I looked it up and it had something to do with the cat converter on the right and left sides or something like that. I took it into Nissan today and they just said "uh...your exhaust was modified so the light will stay on...the converter isnt working properly..uhh". I have a Random Tech Converter installed and it has been there for bout 4 months. Does anybody have any idea how to solve this problem? I also have a cattmann y-pipe and greddy exhaust if that helps any.. Any help would be greatly appreciated.
Thanks..

 

You're getting the "three-way catalyst" code which is really weird. Those catalyst are in your old Y-pipe. Why your car decided to throw a code now is beyond me. I've never heard of this problem before.

Look at the second thread. Answer is in there.

 

Ah....Thank you Bill. I was wondering about that. Its kind of misleading reading several threads concerning this. I was going to get a new cat any way. Now I have a reason too
