O2 sensor locations
O2 sensor locations
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.

Re: O2 sensor locations
look on the exhaust manifold near the firewall- bank 1 is where cylinder 1 is

Re: O2 sensor locations
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.

Re: O2 sensor locations
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.
