P0456 Check Engine Light -08 C4 Cabriolet

Hello all,

I recently purchased my first 911: a 2008 C4 Cabriolet. About two weeks after purchase, my check engine light came on and the error code os P0456. From what I've read so far this seems pretty benign with likely cu'prit being my fuel cap or a vent valve. Does anyone have any experience with this fault? I'm going to try replacing the gas cap first; is that a good start?
