First of all i would like to start of by saying im new to this forum (absolutely love this forum!) and proud owner of a 2007 Chevy Cobalt Supercharged = ) that i just got yesterday with that being said im upset as hell because my check engine light turned on a while ago = (. I went to my local Autozone to get it scanned and these two codes popped up P2A01 and P0137 can some please explain to me what that is the guy i was talking to made it impossible for me to understand lol. So can some one explain and are they bad?Also shuold i still drive it or just wait to take it to the shop?

 

Welcome! You may get better response by posting in the 2.0 L LSJ Tech section. I looked for a list of DTC's for the LSJ but didn't find it in the stickied threads.

Good luck.

 

P0137 HO2S Circuit Low Voltage Sensor 2 ECM, PCM
P2A01 HO2S Circuit Sensor 2 ECM

I would say there is a very good chance that the second O2 sensor has a problem. The second O2 sensor is the one right after the catalytic converter. If it isn't the sensor itself then there is a bad connection somewhere.
