Ok. Having the same code problem but have had it for over a year and never had an actual problem out of my 2006 4cyl automatic until I took it to have new plugs, engine flush, new oil, and fuel system cleaned out. Now It has started sputtering while idling.
I have changed both the cam and crank sensors (the crank sensor appeared slightly burnt with a screwed up ring). I also pulled the actuator to inspect it. All the screens are there and nothing appears damaged. there was a little debris on it but nothing clogging the screens, blew it off by blowing on it. Truck seems to have some of its power back but it still sputters.
I really do not want to spend money on the actuator and it not be the problem though I have to make a 1900 mil drive Friday.
