P1450 Fuel Pressure Sensor?

[Tws777]

Hello everyone,

I have a 2015 Mustang GT with 44k miles. My car was built in June 2015.

My check engine light turned on last week with P1450 (Unable to Bleed up Fuel Tank Vacuum). I don't have a warranty, so I'm hoping to self diagnose and repair. I cleared the code, but it came back on after driving exactly 235.2 miles. I have turned up very little information online about this.

Here are the possible causes I have found:
Blocked EVAP canister or vent solenoid
- Kinked or collapsed hose between canister and fuel tank.
- Faulty fuel tank pressure (FTP) sensor.
- Fuel filler cap stuck closed, preventing vacuum relief.

Has anyone had this and know what the fix may be?
Does anyone know where the fuel pressure sensor is located?
Any help would be much appreciated!

Thank you in advance!

That P1450 is the most common S550 error related to the purge valve. When the valve gets stuck (internal operation), it's causing vacuum issues from fuel tank to engine.

Here's the link with a video showing the purge valve replacement.
