How important are these (4) codes ?

My "check engine went on"... here are the codes... the fuel sensor codes are among them (when does that gauge ever really work right ?)... but I'm more concerned about the others... any input would be appreciated.

P0416
P1416
P1431
P1571

I know that some people have removed the check valve without removing the intake manifold but I believe the service manual says the intake has to come off, once you get to the check valve you can try to clean it out (it will probably be corroded on the inside) or you can get a new one at the dealership, I believe they are pretty cheap, less than $20.
