^^ it seems to go off when its cold out. I know its something to do with the heated o2 sensor but i just replaced the front one and the light is still on. Do you guys think that it could be the rear one. Or could it be a connection? Its going to make me lose my mind soon.

Do you mean the check engine light. If that's the case check your engine oil.

find someone with a datalogger, or go to autozone and have them scan it. If it is the rear one it could be that the sensor itself is bad.. or that your catalytic converter is bad. Hard to tell until you get that code.

I'd agree with Jason on that one. The easiest way is to go to autozone and have them scan it, (its free) they dont even drive your car anywhere if youre worried about that. That way, youll get an instant idea of whats causing the code and youll be able to fix it. Even if you opt not to fix it, youll at least know what the code is.
