Question

I cannot find the bank 2 O2 Sensor I need to replace it but I cannot find it on my buick lacrosse cx 3.8L V6 Engine car. I found the front one that one was very easy to find, but I cannot find the Bank 2 O2 sensor on this car. Can you please tell me or better yet let me know where I can see a photo of where it is on my car or a diagram.
