2001 Nissan Sentra Automatic

I have a 2001 Nissan Sentra GXE and the check engine light came on and I took it to Adv. Auto Parts and they ran the computer and said my system was too lean Bank 2. Im pretty sure I have a faulty O2 sensors. Any ideas on how to replace them?

Thanks

Locate O2 sensor(s) on exhaust system. Disconnect battery. Disconnect oxygen sensor wiring connector. Unbolt sensor from exhaust system. Install new sensor then reverse procedures.
