VGT actuator

[hardrock_f350]

I have a 08 F350 6.4, and the VGT actuator does not go thru a self test when the ignition is KOEO. I can move the arm and there is nothing stopping its movement, when i have the KOEO i can also move the arm fully and the actuator will start to work. the questions i have is 1: is there a fuse that would cause this, i have looked and found nothing open? 2: has anyone had this problem and what did you do to fix it? 3: does anyone have documentation on the wiring and the ohm reading for the actuator?
thanks

Try unplugging at actuator and plug it back in. Maybe its not getting a connection

i did that last week and still the same problem, the only way the actuator works is if i move the arm thru its complete movement while the key is on and engine is off.
thanks

Are you able to move the arm with engine running? If so somethings not right. Also take a test light to the power wire on plug and see if u have power. U may get more help in the tech forums

after i move the arm while KOEO, and crank the engine, i cant move the arm any more. as long as i move the arm while in KOEO the system runs like it should.

I'm sure its fine. It sounds like it working with engine running correct? Does it spool like normal? Does your truck still sound like a hair dryer? If so then its working.
