Does this sound like a blown sensor, or something more? After we got to the Adirondack Mountains for our 2-week vacation, the CEL came on. I dialed up onStar and they tell me "it's no big deal...just see a dealer when you can." I asked what the code number was, and they told me P0054. Then, when I asked what the info on the code said, he said "it's something about the fuel delivery system...but again, not a major issue." +1 for giving me the code, -1 for not being able to tell me it was something about the rear o2 sensor. I texted 20SS07 and he was able to get me some info.

Anyway, now that I'm home, I'm going to get under the car and see what the deal is. Anyone know if the rear sensor and harness are readily accessible?

It should be replacable under factory warranty if you dont have factory it will be replacable under the emission warranty which is 75k i beleive. Considering a o2 sensor is part of the emission system.

Thanks, I know that, but unlike others, I search and if others have had or are having this issue, then this is the place to post it.

I am trying to help out and get help at the same time.

TheMonteMan

perhaps start a new thread asking your specific question.
