This is what the Tech 2 shows:
Preheating O2S2 100% (this value is constant)
Preheating O2S2 480ma (this value is constant)
The sensor's voltage follows the general direction of O2S1, after a slight delay, about half the time. The other half it's going in the opposite direction, i.e., the upstream increases and, after a slight delay, the downstream decreases. And, although I don't fully understand the explanation in WIS, I don't think the preheating values should be constant.
This morning I'll check the sensors' resistance now that they're cold. And check the wiring diagram to see if they share that J16.
Thanks for your response.
