O2 Sensor - Bank 1 Sensor 2

Just a little note if someone down the line is reading this; my check engine light did not go out by itself after the O2 sensor install. I had to clear the codes and the light stayed off.

if you had not cleared the code the light would have gone off on its own as it self test. once it test ok, its set as ready. and the light goes off. it just takes some time. few days to a week sometimes.
