O2 sensors are on the exhaust pipe, before and after the cat converter.

Its showing bank 2 sensor 2. So would that be the second sensor on the exhaust pipe?

Only problem with this is that an o2 sensor code can be thrown by more than a bad o2 sensor. That could indicate an emissions vaccum leak as well. Cel codes are only a basis to begin diagnostic. That's why so many people get pissed off at autozoners when they buy part after a code reading and it doesn't fix the problem

Ya I know...tough to be sure. Just want to know where that bank 2 sensor 2 is thats all.

ah yeah. I forgot to post that. Pass side after the cat. If you only have one o2 sensor behinds the cat, that sort of narrows it down to a definite answer lol
