I have read every thread on this for these faults for the upstream oxygen sensor on bank 2. I have replaced but what is unique is this showed up after changing oil. Like first start. Could that be 100% pure coincidence or could there be something to the oil change? One strange thing I did was blow in oil filler cap with my mouth but could not see how that could be connected?
At least you blew and not sucked 
sorry no idea why but I would think its a pure coincidence.
Wow, just wow. That’s hilarious.
