CEL P2004 APV problems

I have had this on-going issue with this CEL. Yesterday I decided to make sure I didn't have a broken wire going to the APV motor to the computer. All 5 wires checked with continuity. But, as soon as I clear the codes the second time I crank the car the light comes back on. I have even bought another motor for the APV and that didn't help either. I have tested the APV motor via 12v and spins fine and the little white gear spins very easily and freely. But, I heard the APV cycles when you turn the key? If this is true mine doesn't do that.



Any help and suggestions?
