P1211 code

I got A P1211 code out of my truck. The Truck is a 00 F350 4x4 7.3 work truck it has no mods it's bone stock. I got the code from driving it with a OTC Genesis 7 on it - yeah the 4000 dollar one. It's from my freinds work.

So p1211 is hi or low oil rail PSI. Heres the part I don't get. The truck gives up and won't go any faster than 60 65MPH. The injectors sound like they are dry firing and they make a racket. The truck doesn't do it all the time, only when you try to go over 60MPH or pull a big hill. The Genesis told us that when it was running right at WOT it had 37 lbs of boost and 2700 PSI of line fuel pressure. When it was running badly, it could only make 10 lbs of boost and 2000 PSI presure.

So. Do I have no oil pressure or do I have a fuel problem (this is what it sounds like to me)? The Ford dealership has had it twice so far. they replaced the low pressure pump in the fuel rail and the exhaust backpressure sensor, which made no sense to me. Could I have a collapsed rubber fuel line to the low pressure pump from the tank?

PS the problem is not as bad with a full tank of fuel. This boggles my mind. It makes me think that it is a fuel delivery problem.

Thanks.
Greg

P1211=ICP Not Controllable - Pressure Abow/Below Desired

ICP=Injector Control Pressure, which is the amount of oil delivered to the injectors by the HPOP(High Pressure Oil Pump).

Normally a chip/programmer will cause the code because the stock HPOP can't keep up with the demands of the chip(oil to the injectors wise).


However, i believe you said above that the truck has no mods on it,

therefore i would think the quite possible your HPOP is going bad. Thats what it sounds like to me.



However, hopefully a tech will be along shortly to confirm that if it is indeed the HPOP going bad, or if it isn't, tell you what is wrong.





Hope that helps man

Carolina??? 37 lbs of BOOST? THAT AIN'T STOCK!
Max boost from a stock truck, is going to be about 17 lbs.

Our HPOPS VERY SELDOM go bad, they are inferior for higher performance applications, but they very very very seldom go bad.. (Read, I HAVE NEVER heard of one literally failing!)

I also think it's a fuel problem, weak pump, clogged filter, ect... Your 37 lbs of boost tells me you are NOT STOCK! LOL ,, so the ICP P1211 is normal. And probably irrelevant. (Your chip is calling for more than the HPOP can deliver, as most do)
You should check into the Stealth HPOP, definitely will eliminate that code, and supply all the oil you need.

But Noisy injectors, sounding like they are dry, ect... would point to fuel starvation IMHO. (I had a fuel pump fail, man, these things sound TERRIBLE when they run out of fuel,, scary bad)

And from what I know, fuel problems seldom set any codes, I would check the pressure by simply hooking a hose onto the drain on the passenger side, Run it down through the cross member and have someone open the drain on the bowl while the key is just turned on. The pump should fill a quart container in less than 15 seconds IIRC. This would mean you have at least a gallon a minute from your pump. This would be a minimum I believe. If it is less, I would replace the pump, (You could drop the tank and check for any clogging in there, but I have had a couple of tanks down on different trucks. Never seen one dirty, though some claim they have seen it.

All right I don't know how its getting 37lb boost. I'll have to check the boost again. I got the code by driving it until it did it then we scanned it. and that's the code it gave us. I know it got a fuel problem Because the injectors are making all kind Noise.

Can the high Psi fuel pump be bad? I'v have had 3 of thease 7.3s and have never heard of them going bad but I don't know.

Do you have an extended crank?

Do you have oil in your fuel filter bowl?

As said above the HPOP's seldom fail, however the o-rings that are suppost to contain those high pressures can fail and cause a low ICP problem.

On the driver side head, towards the front, right behind the alt, to the right of the HPOP, there is a sensor screwed into the head. Make sure it is not leaking oil. Check the wiring, make sure oil isn't leaking into the harness. Make sure the wiring is good.
