Does the new turbo use the factory wastegate?

This code means the wastegate position is out of range when the wastegate is closed. It is not a tuning or ECU problem.

Hi , i also got the same problem right now , last week i installed a big turbo to my 2018 Civic 1.5T CVT after that i try to pull WOT 2-3 times and the engine check lights turn on , the DTC code is P003A. i didn't touch my original wastegate (loosen / tighten) , but the DTC comes up... can you give me the solution to fix these problems? thank you
