First, I had the diode installed to the IAT sensor. Did this mod since it first came out. Had no problems with it until recently. The code just started the past couple of months. In the back of my mind I kept thinking it was related to the morning cold. Finally decided it was time to get rid of the engine code light from reappearing. Long story short, the wiring harness was in good shape. Figured the easiest way to see where the problem was to put it back to stock. Been fine since. Amazing that a 10 cent part can change everything!
