2014 Ford Flex SEL P0141 Code won’t go away!

I guess what my problem is, is I have traced wires, checked the voltage and on the heater circuit power both loaded and unload. Checked to be sure it is grounding through PCM. I replaced the sensor (twice) last time with a OEM sensor and tested it to be sure it was working properly. the signal wires have continuity and no resistance.

So I don’t know what would be throwing a code other than possibly the PCM is faulty or for some reason the catalytic converter is messing it up.

Yes the code is off right now, but nothing has been done different so I have no reason to think it won’t come back again.

I do appreciate the help and tips
