Broken wire or bad pressure sensor. Doesn't have anything to do with a leak.
Code is set when the FTP sensor voltage is less than .1volts for more than 5seconds.
Gray/blk is 5volt reference. Pin 53 on pcm F on tank plug.
Dr green is fuel tank pressure signal pin 26 on pcm G on tank plug.
Blk is low reference. (ground) pin 8 on pcm H on tank plug
Tank plug can be accessed under the cover in the trunk. Check for continuity and less than 5ohms from a to b on each wire. I'd put money on the sensor. But checking the wiring isn't too bad.
