Correct, and for anyone else....Bank 1 is ALLWAYS where # 1 cylinder is.

Din

ok on my ES its pulling code p1035 says bank 1 sensor one. so that is around the cat convetor area right?

I bought an o2 sensor its the same part # as the one i replaced before, the one on the front manifold. I think they gave me the wrong one. They arent the same are they?

i have found out that it can usually be the mass air flow sensor that causes that code.

Din

really? man i dont want to spent 130$ on a o2 sensor then still show the same code.
