So I have a 2006 Highlander, V6, and it has a bad O2 sensor per a P0037 code. I am currently at school, and can not fix it for another two months. I know I can drive with the bad sensor, but are there any complications to driving with a bad O2 sensor that would force me to cut back on how much I drive (I put about 60-80 miles a week on it)?

Also when I go to replace the sensor I have to replace the set of senors (before and after the cat) or can I just replace the bad sensor? My dad and I have this debate all the time. I argue that if both senors (Bank 1, sensors 1+2) are bad then I would get two codes, therefore I only have to replace one sensor (bank 1 sensor 2). However he argues that when one sensor goes bad the other senor in the bank has failed as well. So who is right, me or my dad?
