Hello,
The right side is the bank 1. The one before the catalytic converter is the sensor 1 (upstream) and the one after the catalytic converter is the sensor 2 (down stream).
The upstream sensor is located on the exhaust manifold and down stream sensor is in the exhaust pipe after the catalytic converter.

I have attached diagrams for your reference.
Please let me know of any questions.
Thank you.
