CEL: evaporative emission vapor blocking valve may be stuck

[UGADawg96]

Just got back in town from a week in Hilton Head on vacation. Went to fire up the truck tonight to get some dinner, and blam, a yellow CEL. Tried a few power cycles, but it wouldn't clear. Drove it to the end of the street and back and parked it. After locking the truck, FordPass showed this error: "The powertrain control system has detected evaporative emission vapor blocking valve may be stuck open and requires service."

This is the only thread that appears in search: https://www.f150gen14.com/forum/threads/21-powerboost-p04ee-code-thrown.7218/

Seems a little more common on other Ford forums and could be the result of either the gas tank filler flapper OR the valve near the gas tank.

Good thing I already have an appointment scheduled for Monday with a loaner due to the previous BISG powertrain issue, so looks like I won't be canceling it.

To clarify, it sat for 8 days in the driveway, we took a different vehicle out of town.

They are ordering a fuel tank pressure sensor and it should be in tomorrow.

For anyone using search in the future, it had a CEL, check engine light, error code P2450.

At least two others have had this issue here:

How was your golf game?

I don't play. Around it too much for work.

Got truck back after a week in the shop and having a loaner.

They had to drop the tank and replace a sensor.

They also updated a bunch of modules and did a relearn on the tranny.
