I get this about once a month in my 2010 GT. Eventually throws a P0456 code. I clear this with my tuner and it returns again in a few weeks. Ford installed a locking gas cap and also replaced a valve. Still does it. I suppose their troubleshooting flowchart will eventually get to the sensor part if I take it back again.
