DTC P003A Turbocharger Boost Control Position Not Learned

I recently had to take my truck (2006 LLY) to the dealer on two occasions. First they found defective turbo vane position sensor and installed a new one. Second found gummed up turbo boost selenoid, installed new selenoid. Now the light came on and it is the turbocharger boost control position not learned. The light has cycled off and the truck seems to be running o.k. Does this mean another trip to the shop?

Whenever the vane position conponents are replaced, the dealer tech must perform a position "re-learn" procedure using a Tech II scan tool. The tech can also exercise the components to verify that they are all doing what they need to do - as a test.
