Fuel rail pressure high code P000F

[kcabbott]

I have a new to me 2023 Bobcat T66 with 176 hours on it. At around 172 hours it gave a P000F fuel rail pressure high code. I changed out the in line and regular fuel filters and it ran fine for about 3hrs and then gave me the P000F code again. The code will go inactive if I restart and run it at below 1800 rpm with the occasional bump to fuller throttle, but if I try to run for more than 30 seconds at higher than 1800 rpm the code comes back. Any thoughts? Bad fuel? Thank you in advance to any help that someone with previous experience with this kind of issue can help with.

Well, first off I would bring the Machine to the Dealer. You have still 3 years of Emission Warranty on it, which includes that issue.
But to answer the question, its either the Sensor in the Fuel Filter Housing or that little Check Valve in the Drain Line is damaged and causing Pressure to build up in the Filter Housing.
