Thank you very much for the quick response. I found that thread as well, and was leaning toward "deducing" that my code was for the exhaust CPS, but then I found a couple of other threads that kept referring to a P0369 code as the exhaust CPS (even further down in the thread you referenced, a post by "vert" says this). That's when I started getting confused.
I suppose that more than one code can indicate the same problem? I.E. both P0365 and P0369 indicate a problem with the exhaust CPS?
I will move forward with replacing the exhaust sensor, unless anyone else has some differing thoughts.
