Thanks for asking your question. I will try and help you out.
There are only four things that can cause a not responding code.
A bad Iva housing.
Faulty harness under the valve cover.
Faulty external harness.
Faulty Ecm.Whenever the code is active. The ecm will derate power.Please reply back if you need more help. I am happy to assist.

Hello Sr
I already replaced IVA,new harness inside and outside, new ECM,actuator 3 replaced twice and the light still coming when the truck is loaded and running over 55 mphNow my mechanic told me that we can use the new kit that is selling the peterbilt to remove the twin turbo and turn it into a single turbo and program the computer to eliminate the actuators
Technician: Cat Man, Cat Engine Expert replied 3 years ago
That’s very odd to still have the code after replacing all that. I must assume the new Iva housing is faulty.

Customer reply replied 3 years ago
my mechanic changed the mount of actuators 3 and 4 to 1 and 2 where it would be assumed that the code went from being actuator 3 to position 1 which was number 3 previously but continued giving same code 93 actuator 3 not respondingthen we rule out the possibility that it was actuators or housing.
