Sorry for the late post here, but I just wanted to give everyone some more info on this problem. I got a '04 coupe, and the CEL thing has been happening for several years now. I did everything all the previous posters suggested (cleaning and resoldering things, haven't replaced anything yet!)...EXCEPT cleaning the contacts. At least I don't remember doing it. I think I did look at it once and it seemed fine. So anyways, this CEL has been an intermittant thing, so tonight I read this thread one more time, and decided to look at it again. Sure enough, the contact was REALLY bad! So the new piece of info that i have is this: You can actually move the copper part of that relay out (the piece with the big piece of copper wire attached to it) and away from the relay so you can clean it easier. To do this, carefully remove the spring and set it aside (DON'T lose it!) then you can maniupulate that contact until you can finally swivel it out and away from the relay point. Now you have an easy and free access to cleaning that contact up. Make sure you don't break that wire that is attached on both ends or you are screwed!! So for now the CEL light is off, but I am confident that fixed the problem, and if it comes back, it's because that contact is getting dirty again. Thanks again for everyone's advice into this apparently common issue!
