This one sent up a flag to me. With ceramic coated exhaust, gaskets, and rubber mounts, I would have to suspect the exhaust system would be poorly grounded. However when I think about it, my O2 are 4 wires. I assume 2 for the heater and 2 for the milivolt signal. I cannot imagine anyone would design a milivolt signal to use a chassis ground as part of that loop. Can you elaborate a little more on this subject?

Interesting. Victor1 said about 14.2 on the low side and you said 11.8. I have never seen anyone give actual numbers just say a very narrow range. Now I see numbers and both are quite different. Is it that different O2 sensors have different ranges? How sure are you on these numbers?
Understand I am trying to learn - not put anyone on the spot here.
