Location and how to replace oxygen sensor

Which one? What kind of problem are you trying to solve?

The first drawing shows the front O2 sensor. It's roughly right under the front edge of the windshield. The second drawing shows the rear sensor. It's a little behind the catalytic converter.

Good evening,

I attached the location of both O2 sensors for you.
