Can someone please tell me what the stock LS1 O2 sensor bank number designations are when viewed on a scanner like the one below?



Here, the top right is B1, top left is B2, and not sure about the bottom. I just need to know which bank number corresponds to which actual O2 sensor on the vehicle.

Thanks.

Ho2s bank 1 is allways the bank containing #1 cylinder . Bank 1position 1 is first o2. Read bank 1 1. Bank 1 position 2 is behind cat. So ho2s 1 1 front left, ho2s 2 2 right side behind cat. Best way to verify is look at scanner reading shut off unplug sensor read scanner as before.
