Any suggestions to resolve P054F default code? Idle Control System - Fuel Quantity Higher Than Expected

Internet search is all over the place from replace fuel filter to torque converter issues.
In addition to CEL with above code.
When I hook up my 5th Wheel Camper ~13k# the truck will not move once in gear. Only idles when applying accelerator.

Have an appointment scheduled with dealer but was looking for any possible feedback here.
Thanks.

 

I have exactly the same issue and have spent a lot of money trying to figure it out plz let me know what it was thank you

I would be inclined to confine my efforts to the converter . A defective one way clutch could very likely be failing . They never get better just worse..

There are some problems if the converter ever was replaced and a converter for a small gas engine was installed where the proper one for a diesel should have been installed. They will both fit , but one is built to handle more power than the other.

 

thanks for replying so this all started when the low pressure fuel pump started making noise and the gas pedal would do nothing when floored and hooked to heavy load so we have replaced fuel pressure regulator and now have installed a fass fuel pump. So with koeo fuel pump comes on and after about 15 seconds pump starts getting loud and fuel stops returning to tank so I'm thinking fuel pressure regulator on cp4 pump but I just read that it is spring loaded and opens at 53 psi and is not controlled by fuel pressure sensor can anyone confirm this?

 

You are dealing with a diesel engine and the answer you are seeking is for a gasoline engine.

 

can you enlightening me more with your theory.

 

To the best of my knowledge,a Ford 6.7 is a diesel engine.

So , is the engine you are concerned with a gasoline powered or diesel powered engine?

Appreciate your tact in requesting some enlightenment.

If it is not a diesel powered engine ,what is the correct displacement?

 

Put new valve body in transmission and fixed problem.
hope this helps someone someday.

 

Thanks for the update.
