DTC P054F Question ?
Yesterday stop for fuel, Started up truck and got a P054F and CEL as per Idash.
Up until then No Problems, truck is 2021 with 4.700 miles on it. Cleared code and I'm waiting to see if it comes back, Also Ford Pass has the code but that wont clear ?
Can anybody give more insight on this ?
Found this bit of Info: Ford/ P054F

Cause:
Did you check your air filter?
I would hope you would not have any mechanical issue with such a new 6.7.
A vacuum leak could be a concern though.
Do you monitor fuel pressure on the iDash? I monitor my DFCM ( the primary pump on the frame rail) in mine. Yours would be from the in-tank fuel pump in the newer models.
- Intake air system restriction
- Vacuum leaks
- Exhaust system restriction
- Engine mechanical concern
- Sludged throttle body
- Damaged intake throttle actuator

DFCM won't be on the idash. Fuel pressure would be.
Take the truck in. As long as the ford pass shows the DTC they should address it.
Check to make sure it has an air cleaner installed and the box is mounted (lid) correctly.

also, double check any additives to make sure they do not contain alcohol or methanol.
are you running winter diesel? some winter diesel has excessive % of kerosene

I would drain some fuel into metal can and do a flash test.....you can google youtube on how to do the test.

I would think its winter diesel, I 'm in Upstate N.Y. I'm running Hot Shot's Anti-Gel. My Dealers service dept. does a lot of trucks and is familiar with this code he believes this will be corrected with a PCM update. going tomorrow for the update.

me personally would only add more lube additives to winter diesel.
gas in the fuel will also cause the error.

I would think upstate NY would have anti-gel in there fuel already. I would stop using it and see what happens. If they didnt use anti-gel it would gel in the hose on the pump. You may be over-dossing the fuel.

I run K100 which has anti-gel properties. I wouldn't run my truck without it.
