Hello,
The fuel tank pressure sensor is located on the top of the fuel pump sending unit.
In order to access it you will have to remove the trunk liner and you will see a access panel on the trunk.
Remove the panel and it will expose the top of the fuel pump sending unit. On the top center of the unit is the pressure sensor (see diagram).

Please let me know of any questions.
Thank you.
