2017 Outback Limited 3.6R - 45,000 miles
The Check Engine Light is Not ON

Using my OBD-2 analyzer, I recently got:
P013D - O2 Sensor slow response - Lean to Rich Bank 2 Sensor 2
P1604 - No description - I don't know what this is
I cleared the codes but these came up again after the next time I drove the car.

I used to commute (daily) 80 miles each way until April. Since then I've barely driven 300 miles and probably no trip longer than 10 miles.
Is the O2 sensor code an indication that I will need to change the sensor soon? Or is is just because of lack of driving? Will a long high speed run clean the sensor?

Additional question - Where is this Bank 2 Sensor 2? Is it Driver side after Cat?

Thanks

I thought I'd close the loop in case someone else had the same kind of codes.
I ran a full engine diagnostic and a few more codes came up. Still no CEL.
Before I started replacing stuff, I cleared the codes again. Then I did a long run (~50 miles at 70mph).
That was about a week ago and none of the Engine Codes have reappeared.
So I think the car just needed a long run to properly get to temperature and burn out any carbon deposits.
