I'm not really sure what to make of this. for the past 5 months I've had this CEL come on at complete random. And when I've had the codes pulled the mech said there were none in the system. I've reset several times and the CEL keeps coming back; sometimes in a month, others in a week, all of which are under normal driving conditions. I have not noticed ANYTHING wrong with my car at all, it runs perfectly fine. I just want to get to the bottom of this random CEL.
any ideas?
