Yes, it does have an open/closed loop indicator.
Another interesting difference is that when I am in DFCO, it stays in closed-loop. Others have reported that open-loop and DFCO go together, but I am not seeing this in my 1999 Saturn. I am thinking, however, if I was on a super long downhill, it would eventually go open-loop if my exhaust-heated narrow-band oxygen sensor cooled off to the point where it was no longer accurate.
