Can anyone tell me what the 2nd 02 censors do? And if they are a must have in order to drive. Nice forum, checked this site out many times in the past and it has come in handy. Got tired of wanting to reply to threads and not being a member. Any help appreciated

They verify that the cats are operating within a set range.

They are a boat load of money to replace. I changed 2 of them out on my '01 Pathfinder, they cost me 250$/each. (from what I remember)
