I just got the P228F code. The truck is completely stock except for the DCR. The DCR was installed last winter and I have had
no problems with the truck up to this point other than this code. Fuel filters have been changed twice and primary fuel filter drained
a bit once/month. Never any water. Truck runs very well. I'm going to clear it and see what happens?
Found this at another site, perhaps it helps:
Another potential fix (recommendation is to replace the whole left rail assembly, due to specialized torque on rail components, apparently).
First attempt was to replace the FRP (which is still retained on the DCR, IIRC):
Well it’s fixed! Turns out some trucks need an updated tune with the DCR pump.
Can you explain or go into more detail about the tune? Who determined the need for a tune, what tune and etc. I'm
going to contact S & S and find out what whet have to say?
I had ACR Diesel in Kingman AZ install my DCR. He (i think it's Brian) has installed quite a few DCRs. I would like to
find out what his experience is with the P288F error code.

I will report back.
His experience and yours may not be related, as he's dealing with tunes for a modified truck. Yours is still stock, so his solution likely does not apply to your case I would think.
However, there are a few of us that have DCR's with unmodified trucks that I'm sure would be interested in hearing anything S&S might impart to you (myself included).

Mine was because I am deleted and running custom tuning.
These are the responses I got back:
S&S Diesel:
Thanks for reaching out. We have not heard of a tune being needed in these situations. From the times we have seen this code it typically points to the PCV. We have seen cases where the PCV inlet screen was clogged or the PCV itself was faulty. We have also seen a few cases were resetting the adaptive learn values and driving it for a few miles gets rid of this code. I would try these first and then reach back out if you are still having the issue.
Thanks,Isaac Horton Technical Sales Representative
Brian @ ACR Diesel:
Hi there, we have installed a myriad of the DCR conversion kits and have not had to install/download any type of tune for them
to function correctly or not throw a code. I have seen that code on multiple vehicles, but typically that code comes from an issue with the pressure control valve. The DCR pump does create greater fuel flow, so if that valve has any debris or functionality issues, that code will come up for it.
He goes on to say that he recommends changing the fuel filters first and see if the code comes up again?

I would follow what they say, you don't need a tune if your truck was never tuned in the first place. A tune isn't going to help you, it is something mechanical.

Seems he recommends it likely to be the same from what was mentioned in the screenshots I included previously.
I would follow what S&S recommended, first, then look deeper into possible PCV issues, or other potential fuel issues. Probably wouldn't hurt to try forcing a relearn, if you have the ability to do so using ForScan, perhaps.
All this is predicated under the assumption that you're doing this yourself. But, isn't your '23 still under warranty? If so, get it to the dealership (but only if it's still showing that code, they won't do anything to it otherwise).
I reset error code and the permanent code with forscan yesterday. Take it for a drive to get the new motorcraft fuel filters
this afternoon. I will see if the code reappears? If it does, I will change the filters. If the code appears again? I will change
the PCV and hope for the best.
How is a relearn preformed? No experience with that coming from an OBS. If I can, I will do that before the PCV.
You can instruct ForScan to perform relearns. There should be two relearn procedures available in ForScan, IIRC; one for the PCM and another the TCM. Unless I'm not recalling correctly, someone call me out if I'm wrong...
As far as the Pressure Control Valve, and from what I posted earlier, they're part of the injector rail assembly, and it's likely better just to replace that whole assembly.
You still haven't answered whether your truck is still under warranty. I wouldn't think your mileage disqualifies, with it being a '23? If it were me, I'd get the dealership to pay for any repairs if the warranty is still in play. Just make sure that the code is present, and they'll take it under warranty. But, that's me.
My truck is a 2022 with 72,000 now. It was a high millage fleet truck, excellent maintenance and purchase price. I got a 3 year
extended warranty included. With a DCR installed, how far will the warranty go with Ford?
We are full time RVers. Being in Arizona this time of the year. A lot of dealers will not even do an appointment. They want you to
drop it off and they will get to it, when they get to it. That's not acceptable for us. I do as much as I can, but there's only so much
one can do in the desert.
I did a relearn. Drove 45 miles to pickup the filters, no code. Friday we are pulling the camper about 350 miles, mostly flat. We'll
see what happens?
