I bought a 2000 civic si em1 to restore since it was in a crash and it is throwing cel 67. its the catalytic converter. this car still has the catalytic converter and the only thing not stock is some exhaust. its not that big of piping so i wouldnt think that would mess it up. anyway is there a way i can fix it or disable it before i sell this thing.

disabling it then selling it would be a crime...

replace the secondary O2.

alright you sure its the o2?

that secondary sensor is basically there to tell you if your cat is doing its job. replacing it should do the trick.

ok sounds good but i also have a b16 crx and i was planning on doing a cat delete. would that throw the code on my crx. its a obd0 jdm b16a.

only OBD2 has the secondary O2. So no it will not throw that code if you run it OBD0.
