Threw a P1450 this morning

P1450 - Unable to Bleed Up Bleed Fuel Tank Vacuum

• Blocked EVAP canister or vent solenoid
• Kinked or collasped hose between canister and fuel tank
• Faulty Fuel Tank Pressure (FTP) sensor
• Fuel filler cap stuck closed, preventing vacuum relief

I've only seen this in the past when your gastank cap is loose or not sealing - but since ours are capless ...

I checked the flapper in then filler tub - nothing obviously wrong.

I have all the bolt-ons - intake, exhaust, Cobb tuned, SPD downpipe couplers, ...etc - but nothing messing with the fuel system directly per se ....

Any one with experience or ideas?

Just wondering if you ever found out which of them was the culprit. My ‘18 Raptor just threw this code and looks like the solenoid is the easiest one to try first followed by the FTP under the truck

I swapped the unit - haven’t driven enough to complete a drive cycle - take a long time - but haven’t thrown a CEL yet

 

[Quiker]

Just passed my emissions inspection today - no CEL and every emission component can ‘ready’ status

/whew

Here’s the video to swap the part

Tricky to find the part number

So it was the purge valve for this case?

 

[Quiker]

it was - it caused
- P1450 - Unable to Bleed Up Bleed Fuel Tank Vacuum
- P0420, P0430 - Catalyst System Efficiency Below Threshold Bank 1 and Bank 2

Interesting.
