That is your lambda /// oxygen sensor you have replaced
Bank 1 is the one at the top, or first one of the two...
Are they the same sensors, could you have possibly put two in one .
Also are they generic ( not main agent parts)
And most importantly,,,, why did you change them..
If generic, what colour are the wires. Heater element, usually means 4 wired lambda, wires right way round..
