P0237 Low input voltage for boost pressure sensor "A" for current engine conditions

P0336 Crankshaft position sensor

Added a Edge about 1 1/2 months ago with out codes.
Changed fuel filter, oil + filter, and air filter and got these codes next day.

New to this stuff, what do I check or fix.

Thanks

Ordered a new Crank shaft position sensor. Any room at the Cave Friday or Sat to put it in? Gotta pull the starter does not seem to hard to do but with no garage....

Thanks Scott
