Greetings. I'm new to this forum and already a big fan. I'm trying to find the locations of the O2 sensors on my "new" GXP. I have a P0135 code and am not sure of the location of the bank one, sensor one location. Any info would be greatly appreciated. Thanks.

look on the exhaust manifold near the firewall- bank 1 is where cylinder 1 is

There's 3 O2 sensors, one on each manifold and rear of Cat. The 2 on the manifold I can not lie, are a royal PIA to change.

I can now wholeheartedly agree with your assessment on them being a PIA to change. I changed the back one between the motor and the firewall last weekend. My hand is still healing from the skin I left behind. All changed and working now anyway, so hopefully won't have to do that one again. Thanks for the posts with the info.
