Codes P0455, P1273, P1283

So my car is throwing three codes.. The P0455 is saying an evap purge valve short. and the other two are saying a/f sensors ?
Anyone have any ideas on wtf it could be ? Id rather not buy the o2 sensors if their only throwing a code because of the evap, but Im not sure why the evap would throw a code.. Any help is appreciated.

Diagnostic logic in the a/f ratio sensors does not rely on the evap system for inputs. First step for the a/f ratio sensors throwing both codes at the same time is check the grounds one is by the steering column the other is behind the glove box. if thats not it you might have gotten the fluke both are actually bad i have had it a handful of times.
