P2290 Code

Have a late model '04 F250, with 156K on the motor. The motor was bullet proofed at 154K with complete valve job, gaskets, ARP bolts, upgraded EGR, fuel/oil exchanger, clutch fan and new filters and fluids.
Just got a P2290 light with low power under load. Ford says ICP under load is 650psi, IPR is 85% and code won't reset (no other codes). Ford wants to replace HPOP for $2K and then recheck it. I suspect a possible leak however considering the labor to get back in there shouldn't i just replace the HPOP, pipes, plugs etc and call it done or should I have them chase down the possible leak.
Another shop said he would pull the valve covers and run high pressure air to determine leak for three hours labor and then look deeper...sounds like a respectable approach, thoughts on replacing everything if he has to go that deep vs just fixing the problem with the current mileage.

Re: P2290 Code

Is your icp located on the right front valve cover? A monkey could run a hpop air test, that is the best and most logical test to start with. There is a hpop air test too, let me get that link for you. Stand by...........

thanks to both of you, excellent video and straight forward. I cant tell you where the ICP as I am military overseas right now and vehicle at my fathers house. The manufacture date was May or June 04, so definitely the late model series 04. I am going to have to pay someone to dig into this problem, but need to have the best knowledge prior to going in as my father is not up to speed on diesel.

Re: P2290 Code

In that case, the mechanic has the sensible approach to the problem. A hpo leak test is in order, from there, the icp/pigtail could be bad, the ipr could have trash in it keeping it stuck open, or the standpipes could have failed orings, then lastly, the hpop could be going bad.

if it's not having any trouble starting hot, it won't be a leak. guaranteed. not with an ipr command of 85% and 650psi under load. if it were, with those numbers, you'd be having serious trouble getting it fired up even warm.
in all honesty, it probably is the pump. either that, or the ipr.
pretty simple to figure out. command the ipr shut. air up system. if air pressurizes crank case, replace ipr and retest. if air exits the oil filter housing, replace the pump

Gents,
Thanks for the help, mechanic says he found metal in screens and that HPOP is gone, will replace the IPR, ICP, HPOP, stand pipe and dummy plugs etc. basically everything while he is in there. Oh and an oil/filter change. $1200 labor, $1500 in parts.
thanks for the advice.
