I did get a response from one of the tuning gurus on Third Gen.
I think that it can. The ECM usually just looks at the O2 sensor voltage for closed loop determination. That is either lower then a set value (200 mV) or higher then a set value (700 mV).
Because until in closed loop with prop gains there may not be x-counts.?
I have had instances where one of the O2 sensors would report a string of 0 volt readings, ie during cruise, and would still stay in Closed Loop. However, it could exit Learn mode after a certain period of time.
One of the reasons I switched from Bosch sensors. I don?t have that issue w the AC sensors.
