O2 sensor bad

I just came back from the shop to get my check engine light look at on my 06 GTP. And my rear O2 sensor is bad. :mad: The mechanics said that it cost around $544 :eek:to replace it. Does anyone have had this issue?

Did the dealer give you a part number? That should take the guessing out of the price tag.

I had the bank 1 sensor 2 (the rearward most sensor) go out of my 06 GTP 3.9, and I got it for like $80 right from the dealer (AC Delco) and installed it myself.
Was it just plug and play? I also have an 06 and want to make sure I don't have to worry too much about this.

I have a connection at a dealer in my home town, but don't get to talk to them too much when I am out of state. The GM dealership there has always shot me straight when I needed something taken care of. I even had one of the mechanics pop the hood for me and show me how to install the transmission cable on my Sunfire myself instead of paying him $300 to install it for me.:D
