Any direction on the site here where to decipher engine codes ? I pulled a P0001 Fuel Volume Regulator Control Circuit Open code .

 

P0001 FORD - Fuel Volume Regulator Control Circuit/Open

Repair Importance Level: 3/3
Repair Difficulty Level: 3/3





Possible causes

• Faulty Fuel Volume Regulator (FVR) Control Solenoid
• Fuel Volume Regulator (FVR) Solenoid harness is open or shorted
• Fuel Volume Regulator (FVR) Solenoid circuit poor electrical connection

What does this mean?

Possible symptoms

• Engine Light ON (or Service Engine Soon Warning Light)

P0001 FORD Description

The Powertrain Control Module (PCM) monitors the Fuel Volume Regulator (FVR) and Fuel Volume Regulator Return (FVRRTN) circuits to the PCM for high and low voltage.

thanks , seems I don't have a repair manual now when I need one to know voltage draw and resistance values in the wires .

 

There is no such code (P0001) for a 97-2003 F150.
Read the code again.
My reference is the Ford service manual and the OBDII overview plus a chart from another source..
None has such a code for this truck with any gas motor equipage..
There is no monitor on the fuel system regulator because its mechanical and pressure is varied by vacuum line to the intake manifold..
If you have some other vehicle, what is it?
Good luck.

 

I don't know what kind of Ford manual you have but I am not blind and that code certainly does come up on my scanner tool and it is listed as such on trouble codes.net and other web sites to check on . The Ford manual might have their own English they use but its their code off their vehicles computer .

 

If you are getting a P0001 code on a 10th gen F150, then you have some computer problems (or a scan tool issue, what are you using to pull codes?).

As said, this gen has a vacuum controlled fuel regulator, no electronics hooked up to it, so no way for the code to show up unless you have a computer (or scan tool) problem.

What symptoms are you having? Is the MIL light on?

 

Neat, he comes here for help ,refuses the info with references.
The fuel system is a two pipe system that feeds high pressure to the injectors fuel rails where the mechanical regulator reduces the pressure to about 38 psi.
It has a vacuum line control to further reduce the pressure at idle when the motor does not need as much fuel.
Open the hood and look! If you find any wires attached, I will be the first one to eat my words.
All the codes you may find on a list or displayed on a Scanner don't apply to every and all years and models. Example a Diesel that shares many codes with a gas engines and some for functions a gas motor does not have.
A single pipe fuel system is monitored for functions a two pipe system is not.
Single pipe systems started in 2004 on the F150 trucks.
You have to know the differences.
Good luck.

 

its a 2003 FX4 with the 5.4 . Sorry I cant camp at my computer very long . It has the service engine soon light on the left top corner of the dash .


Its not a scan tool issue . I can feel the engine at road speed with a rough mid range speed problem . Its going in to shop to be checked over . Thanks any how .

 

Let us know what they find. I am wondering why you're getting a P0001 code on a vehicle that does not have that system.
It is like getting a code for an electric cooling fan malfunction on your truck, you just don't have one.

 

Well here is the rest of the story , had the local Ford Garage diagnose my problems he came up with a miss fire code on 1 and 6 cylinder , all together different than my code reader read which indicated an open in the fuel system electrics . This mechanic said he has noticed vehicles coming in that had not been driven over the winter ( like mine ) for a length of time . He said a sticky fuel injector can give off a code that resembles a miss firing spark plug . Pulled out the 2 spark plugs that were indicated as miss firing and they looked good as I had replaced the spark plugs not long ago . Told me to get a bottle of techron fuel system cleaner and dump it in the fuel tank . But before he was out the door with it , it seem to develop a noticeable miss again so he rechecked for codes . This time a bad coil was indicated so I was told . So in went a new 94.69 dollar coil . The thing runs smooth now . He looked my code reader over and said he never saw one like that . It was a cheap code reader maybe not worth the shipping cost either from china . Some how all the past history codes were also deleted which could have helped him out . I noticed that also . So its a good idea to add some fuel conditioner to any vehicle that sits any certain length of time . I never thought over the cold winter months fuel would go bad but now know other wise .

 

So now what have we learned?
Code reader no good, my references are no good so I am told.
.
If you do a code clear, remove battery power or alter the program the computer goes into full diagnostic.
There will be no codes or CEL until the program finds a failure in any of its tests it does.
If the shop will look at mode 6, test 53, he will find the misfire records for all 8 cylinders after the motor is run a few drive cycles so any record can accumulate after having been cleared previously.
Then you work out remaining issues one at a time.
Good luck.
