Bank 2 sensor 1 location

I have an engine code of PO154 O2 sensor CKT No Activity (Bank 2 Sensor 1). Can anyone tell me where this sensor is located. I believe that I read somewhere that there are 4 o2 sensors. Is this correct?

Bank 2 is on the left side of engine, driver side. Sensor 1 is before the catalytic converter.

Thank you for your response. Do you know if there are actually 4 of the O2 sensors? If there is more than one do you know if they are all the same part number.
