All, quick question. I just changed my valve cover gasket and am left with this P0365 code in sensor B bank 1. I have searched the web and was able to narrow down to passenger side sensor (Left side If I am standing facing the front of the engine) . What I cant find is which sensor is "bank 1" . There are 2 sensors on that side of the engine. Is bank 1 the one on the upper right or lower left? I am guessing is the upper right but just looking for confirmation. Thanks for reading.
