Couple of codes and no boost

[captain extreme]

Hello, have a couple of codes, been googling with no luck.. 21 850T, engine lights at end of the day, P1477 and P1475. Sled isn’t building boost as since the cel’s.

Anyone know what these are?
Anyone ever have their 850T not build boost?

P1475 comes up weird, almost like electrical

Check the arm on the wastegate is still hooked up. The circlip was falling out that holds it on on a few sleds last year I guess. I carry one in my tool kit just in case.
