2017 Volvo VNL + D13
Every time this truck hits a hill, it generates this code and significantly loses power for the rest of the day. We have done all the basics, like check fuel filters and even changed a harness (I believe) for the EPRV system under the valve cover. ALSO, we got a hold of an EPRV-delete kit and it was installed with reprogramming by Dothan Volvo. Driver took it out on the first load and same problem returned. Any ideas?????? It's been one thing we can't solve -- and there's very little info on the Web about this code.
SA 16 DTC P228F00
He's able to get back to speed on flat ground and make his trips but his power is quite reduced. So it's certainly not a 5 mph derate, and I don't suspect it's a derate of any kind because there's no warning or advisory on the dash saying he's derated.
He DID have a code that pointed to the particulate-matter sensor, but those allegedly do not cause de-rates or affect performance. Is that also for sure on these D13s? That code is DTC P24B100
Any help or insight would be appreciated!
Help -- a year with this problem! SA 16 DTC P228F00
usually every code they have comes with dummy diagnostics is what i call it it will give you an idea of what is causing the fault i would check the fuel psi sensor on the rail they are notorious for failures also harness has to be update with sensor as well.
Sadly we are still chasing this problem. He's still losing power on even tiny hills and still getting the P228F00. I've confirmed this morning he has the correct new fuel-rail-pressure sensor in, Part No. 23488939, which is a Delphi component with its own part no. of 28672623. We've put that sensor in, changed the harness, done an EPRV delete, and this still happens. Whenever he hits a hill, he can expect the power to drop drastically. Oddly he won't have the same problem fully loaded and flooring it to build speed on an onramp. The condition lasts for the whole day after that. After a shutoff and restart, it goes away. Because of this, he's staying in flat states.
We're wondering about external causes now, even crazy ones, like ping-pong balls or sand in the fuel tank or something restricting fuel flow in a filter housing -- anything that would cause erratic fuel pressures. The code description for P228F00 is "Fuel Pressure Regulator Exceeded Learning Limits -- Too High, No Sub Type Information." Is there even really a "fuel-pressure regulator" on the engine??
Thinking of diagnosing with help of a dyno???
STILL STUMPED. Help apprciated.
P228F00 DTC Fault Code
The fuel pressure regulator 1 has exceeded the training limits - too high a pressure
In some technician opinion you have a stuck close valve.
The pressure gets too high and a temporary engine de-rate happens.
The fuel pressure should be regulated by a return valve.
Not my personal opinion. I'm just a driver. Retired driver.
I just asked a friend. Maybe it'll help you. Maybe not.
