Where are the fuel tank pressure sensor located?

Hello,

Just to clarify, are you having issue refueling the car?
By pressure sensor do you mean the purge solenoid for the EVAP?
Are you getting any code?

There is also a refueling control valve that goes on the tank.

I have attached diagrams for the refueling valve, EVAP solenoid and other components for your reference.

Please let me know if you need any other info.

Thank you.
