Turbo Actuator Operation

[markam]

OK...So I am getting a U010C code which I can clear and it stays off for a day or so before coming back on.
The code is loss of communication with the turbo actuator. I don't see where it could be intermittent with all the connections secure?
I wonder just how the actuator sends these codes.
1. Is the actuator being jammed by the moving vanes in the turbo being clogged and thereby sending a over amp draw?
2. Is the actuator shorting out internally?
3. Is the PCM acting up?

Hate to throw a new Holset turbo ($$$) at the problem if it is something simple.

Sounds like an electrical issue. Do you have any wires on the actuator plug that are worn through or partially broken?

More the likely in side of actuator eventually it will throw another code and will see not building boost probably. What your see with that code is the beginning of actuator going out. We always hope something simple 9out of 10 not.

Hoping for something simple.
Took the truck out last night and with the EB on went around the hills in the neighborhood in 2nd. Turbo spooled up and the EB worked. Worked the actuator hard.
This morning went out and no code. Took on the freeway up hill and down. Everything works fine and no codes. Hope it stays that way.

When mine went out in my 13 I did get intermittent code for awhile but eventually got a second code then performance issue. Keeping in mind I put on 12000 miles a month . Hope for the best there.

how many miles are on the turbo? its prolly an actuator issue when it heats up it stops communicating and then will get stuck the the position it was last in which is bad for the headgasket so be careful about that. the pcm wont detect thats theres a issue at first it will eventually throw a code after a couple days. you dont need a whole new turbo. Test the actuator and if its bad then get it rebuilt. i have this same issue but i dont use my engine brake so i unplugged the actuator so it stays open while i wait to buy a new turbo kit

Just curious why a lot of folks don’t use or like using the EB on their trucks?
I leave mine on all the time. I have 65,000 miles on my truck and my brake pads look practically new.
I think it’s one of the best features on these trucks.

I leave mine on all the time as well. Needed brake pads at 105k miles.

me personally i like having the eb but im not in need of it since the actuator is going bad and im debating on either keeping stock turbo with rb and putting a hardway kit or just a 2nd swap

The problem is even when doing that there can be electrical problems. I have a turbo issue but no codes. The turbo freezes up after a hot stop and cold down. It also seems to sound plugged up most of the time with no codes set. I like to use my EB it seems to hang at times. Trying to save for some software help.
