Ah. I thought you were looking for performance. Well the last sensor monitors the efficiency of the cats. The only way to turn the light off is to install the sensor again or to get that simulator. I would personally install the sensor again. As far as staying in open loop that may be caused by something else but I'm not 100% sure. I'm assuming you got the code read? If not go ahead and do that.
