Answers :

P0456 is a small vacuum leak - see if you can trace down the vac lines for inspection according to the diagram that's on the sticker under the hood (it should be near the end of the hood prop on the covering over the radiator). I just took a picture of my 2002 Chrysler Town & Country but to get it small enough to upload you can't read the detail.

\015\012P1684 is an easily trigerred code that is from a diagnostic reader or battery issue - not 100% sure of it's cause but it does not trip the engine light.
If both codes came at the same time and you didn't take the battery cable off, you need a purge solenoid, $40 near master cylinder. Put 3/4 tank of gas and the light will go out buy the time you get to 1/4 tank.
