I was mistaken, there are 4.
I replaced the (bank 1?) driver's side "upstream". I left the others alone and reset the light. We'll see what happens. They don't seem that hard to get to but the downstream connectors are a pain to reach.

I rented the sensor from the auto parts store after they told me the codes and I purchased both sensors. Bank 1 was easy, Bank 2 was hard, but my 13 yo has small hands and was able to loosen and start tightening it for me. Then when the check engine lights came back on I took it to the Ford dealer and they replaced a leaky hose. Learned my lesson.
