There is a "closed loop" flag in TP. That's what I'm looking at. It runs closed loop when driving and at idle when hotter ~ 180ish.
I think O2 sensors are OK, seem to vary while running.
I was just curious as to the actual criteria used in ECM -haven't been able to find specific detail when googling around
