Bought a new one at my local dealer.

I have a 2015 Silverado with the 5.3, it is my first truck so thats why I am coming here to look for help. Truck goes into limp mode when slowing down and off of the gas. I have replaced the actual peddle assembly itself after recieving the code P2128, but after replacing it now goes to P2138. Just looking for any insight anyone may have to this problem. Thanks!
