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?
