Turbo actuator code

[Kljjr0456]

My dash is showing stop engine and check engine light. The code is turbo actuator. The turbo and actuator were replaced at a KW shop early last spring. I show full boost and can hear the turbo spool up. Not sure if it's just wiring but was wondering if anyone had some advice. I'm currently parked and was going to call a shop in the morning. CM 2250. Thanks for any help[/size]
