The code is specific to bank 2. See pic 1 below. Did you replace the one on the passenger side of the engine compartment or were both replaced?
Next, when you tighten the new sensor, it is important that it is to specification. It should be tightened to 18 ft/lbs. Is that what was done?
Let me know.
See pic below.
