What is your question?
I am told I need to replace the Bank 1 Rear O2 sensor. However O2 sensors are sold as Upstream/Downstream, Left/Right. I understand Rear is Downstream. Question: is Bank 1 left or right? Car is 2015 Nissan Murano SL Front Wheel Drive

How annoying, right? Bank one is the one closest to the firewall, or vehicle interior, back of the engine compartment. The good news is that it appears both "rear" oxygen sensors are the same part number!
