This one is easy. The clutch fan is not disengaging. Mine does the same thing after it has idled a while but then will release (wind noise stops) after getting up to speed.

These trucks have a drive by wire system,we seen a` lot with a broken ground wire on the rear of the drverside cyl head,this is hard to see just feel and give the wire a tug .If the wire is loose or broken the reduced engine power light will come on.

THE CAM SHAFT ACTUATOR IS LOCATED IN THE CYLINDER HEAD ON THE FRONT RIGHT HAND SIDE JUST ABOVE THE POWER STEERING PUMP. AFTER YOU REMOVE THE ACTUATOR CHECK TO SEE IF ANY OF THE SCREENS ARE DAMAGED OR MISSING. IF SO REPLACE THE ACTUATOR. ALSO CHECK THE CRANKSHAFT END PLAY. IT SHOULD BE BETWEEN 0.0044" - 0.0153". if excessive crankshaft end play is causing this concern, it will be obviously out of specification by as much as.050" or more when a pry bar is used to move the crankshaft back and forth. IF THIS IS THE CASE AN ENGINE REPLACEMENT IS RECOMMENDED DUE TO THE AMOUNT OF DEBRIS IN THE ENGINE. IF NO EXCESSIVE CRANKSHAFT MOVEMENT NOTICED REPLACE THE CAM ACTUATOR. IT WILL ALSO BE NECESSARY TO DO AN OIL CHANGE.

You need to check the cam phazer and see if it's damaged. Lots of the time it leaks oil into the connector and messes up the wires. Also I've seen the oil control screens come out of the phazer and go into the engine, which will also set the coeds. If I were you I'd pull the phazer out and see if all 3 of the oil control screens are there. My bet is one will be missing. Make sure to change the oil too. You may get lucky and it will have made it to the oil pan? Other wise I wouldn't worry too much about it. Most of the time it will not cause any engine problems. Good luck, oh and you do have to pull the power steering pump off to get the phazer out. But you can just take the bolts out for the pump and let it fall down so you can get the phazer out!
