O2 sensor issues

[loggerboy84]

I have a 2016 expedition, we just changed catalytic converters and o2 sensors and after driving about 50 miles it is saying the bank 1 upstream sensor is bad. Has anyone else had this issue?

Looks like I'm having the same issue...

I can't get it inspected without the cat replaced, but the O2 sensors won't engage either.

I've got a 2013 King Ranch with about 160k

That happened on my 07 around 220,000. If they say it's the pcm don't listen to them, I replaced mine and it fixed nothing.

What brand of o2s did you use? I'd stick with oem or denso if not oem
