Default O2 Censor/P0138 code

So I had the engine light come on in the TJ this morning driving home from work. Checked the code when I got home and its giving me P0138, which my research has shown me is an O2 Censor? Is that right and if so how hard is it to fix? And if I don't fix it right away what would happen? I have to go to work tonight and its my daily driver. Thanks in advance!

(I have an 2001 TJ sport, with about 165,000 miles on it. 5spd manual)

Update: bought the sensor, but haven't installed it yet. I filled up on my way home from work and after the gas tank was full and I pulled out of the station, I saw the check engine light turned off and has remained off for the past two days. I'll continue to monitor and see if it comes back on I guess.
