The Bank 2, Position 1 sensor is screwed into a fitting on the top of the exhaust pipe. Follow the exhaust from the manifold down and back.
In my experience, the B2P1 O2 sensor is reached most easily from the top using an O2 sensor socket and a lot of extension to get the ratchet handle high enough you can get some leverage. But first, follow the cable to the orange connector at the rear of the engine. I pull it up an off its mounting to make it easier to disconnect. To disconnect it, squeeze the tab on the sensor-side cable end of the connector and pull. Look at your new sensor to see how the connector release works. It's a very easy job once the connector is unplugged.

Rather than buy new O2 sensor(s) they are easy to clean providing you are careful, Nothing to lose if it fails.
