Toyota Sienna P1135 A/F Sensor???

My check engine light is on my 2001 Toyota Sienna and when I took it to Auto Zone the scanner said P1135 Air Fuel Metering. From the research I've done, I found this code means the Air Fuel Ratio Sensor in bank 1 sensor 1 is not working. Is that correct?

I am not sure where this sensor is though. Is it in the front of my van or the back? There are so many different O2 sensors/ A/F sensors... front, back, before cat after cat... some sites say 2 sensors are needed. This part costs around $200 and I don't want to get the wrong one... can someone help!

Bank 1, Sensor 1 O2 sensors are usually BEFORE the catalytic converters. It will be shortly after the exhaust manifold coming out of your motor. Here's a link that "may" help you.

Here's the exact code.
