Toyota Repair: RAV Check Engine Code, o2 sensors, sensor location

Question
Hello
Had a Check Engine light come on, so I had the code pulled. It is a P1155. According to Auto Zone, that is a Bank 1 Sensor 2 Air/Fuel (O2?) sensor.

Can you confirm that the Bank/Sensor location is correct for that code?

Also, the Air/Fuel and O2 sensor is the same thing, correct?

Thanks

Answer
The code is for the a/f ratio sensor bank 2 sensor one, the a/f and o2 sensors are not the same, a/f sensors are used in front of the catalityc converter and O2 sensors are located after the converter, on the rav4 there are two a/f sensors and two O2 sensors.
The bank2 a/f sensor is located in the exhaust manifold at the top on the left side when standing in front.
