I am guessing mine are... I get no readings from them at all on efilive. LTFT are all zero. Why I ask is that I have no ses light and no DTCs. I would have thought if they were dead it I would see that little warning on the dash. Anyone else have this happen?

There is a heating code that it will show. If you have your car hooked up to a GM Tech II tool they can even tell you if they are reading really lazy or completely shot.

went to replace the ones I have (just to be sure they`re ok before tuning)

found out that only the front right side is connected?!and the front left is missing a connection between the harness and the sensor ,made me really sad and angry but I shoud`ve checked the car myself before buying and not letting my freind go .....

the shop that inspected it didn`t tell me only one is working we all assumed that the O2 code was because of deleted back sensors (LT headers) ... and I have the ses because of few things including some code about O2 sensor don`t remember .

Might wanns check your left rear 02 and spark plugs. I had one front 02 go bad and it fouled all the plugs and carboned up the rear 02. I just used a propane torch to clean the 02.
