    Has ayone replaced their Bank 1 Upstream O2 sensor? This would be the one facing the firewall side of the engine… I have spent a little while looking at it from the top and the bottom and I don’t see a way to reach it.

    Any tips or ideas would be welcome, thanks!



    hey cowboy,

    Did you ever figure out how to change that o2 sensor..I have to do one as well on a 2006 and just can not figure how to get in there…any help would be appreciated.
