6.4 no boost at all and p132b code

Hello New here. My pickup has no boost at all and obviously no power at all. It's a 2008 6.4L. It's throwing the p132b code. Stuck turbo? Help!

That code is for the Turbo actuator self test. The PCM is reporting the actuator position does not match up the position commanded. Sounds like the sensor or actuator are bad, loss of power would indicate to me the actuator is not moving the guide vanes.

I have never tried to change the actuator, so I can't help you there.

You can visually check the actuator by looking at the "dog-bone" on the top of the turbos. 1. make sure its still connected, 2. when the ignition key is turned to "run" (not start), the actuator cycles (if working correctly you should see it move forward, then backward), you'll likely want someone to assist as you can't see it from the drivers seat with the hood open.

Ok it's in a different town than I am in now but if that is the problem would that make my turbo not spool at all because I'm pretty sure I've got a stuck turbo. No boost, no turbo sounds at all and so little power I can barely drive it.

it could be the actuator but since the code is determined by Position sensor built in the actuator module I would say it is actually the Linkage (Variable Geometry Turbocharger (VGT) Actuator Linkage.

Visually inspect the linkage to the actuator to make sure it is physically connected. most likely this code comes on because something might mechanically binding in the turbo.

just to rule out everything else after the turbo you should perform a exhaust back pressure test. if you have scanner is even better, perform the Key On Engine Off (KOEO) and Key On Engine Running (KOER) self tests with a scanner to be sure the code sets as a hard fault. if the code doesn't come back you might have a restricted DOC Converter or DP Filter.

Are you talking about a code scanner? I cleared all the codes and drove it around the block a little bit to try to get the code to pop again, but it wouldn't so I loaded it onto a trailer and when I went to unload it the code was there again. I'm out of town now but I'll be back this weekend and I can check everything around the turbo and make sure nothing is disconnected. Thanks

Ok I have checked it and the "dog bone" linkage is connected and when I had someone turn the key in the on position the linkage does not cycle like it is supposed to. But you can hear it clicking like it's trying to

With the engine off you should be able to cycle the linkage by hand back and forth. If you cant move the linkage by hand I would try to undo it and see where it is binding up whether it be at the turbo or the VGT actuator.
