I have the same code, it's low voltage to MAF. I replaced my MAF with a year-correct used MAF (xxxx05 instead of the xxxx04 that was in it) and while I was at it got rid of the oil K&N (sometimes they get oil on the MAF and it kills it), but still had the code. Although it fixed some of my specific rough idling issues. I've since determined that it's a wiring issue somewhere, and I'm going to take a Ohms tester and figure out which wire it is. A wiring diagram makes this not too bad of a project, abit tedious, although I manged to loose my diagram somehow...
