02 Sensors

I need to replace upstream 02 sensor, which will be bank 2, sensor 1. But my question is do I have to change bank 1, sensor 1 as well or it doesnt matter?

this is the welcome section. the short answer is you only need to replace a sensor if it is faulty. They do not need to be replaced in pairs.

What have you done to determine b2s1 02 needs replacement?
