Yes, common issue with aftermarket locking gas caps, the cars don't like them. We've tried Stant and other brands, but about 8 out of ten throw the code right away, the rest do it after a few starts. Put a nice new Porsche gas cap on and the problem (after you clear the code) will not return.

We eventually gave up on locking gas caps; the car's EVAP system is too sensitive…………….

if you cant clear the code it will go away after a few tanks. once the evap system does a few cycles.

Bump. ^ True. Learned that the hard way. While the topic is about locking gas cap, what do you think of last year's sales of gas cap. Here's a blog I saw on the net but it was 4 years ago:
Sale of locking gas caps triples in 2008
