It's not a shield. It's a coil or solenoid valve that is then pulse width modulated for adjustment of pressure. The IPR is a pulse-width modulated valve operating at 400 Hz. The pulse width is modulated from a duty cycle of 8 to 50% to control injection control pressure from 3.4-20.7 MPa (500-3000 psi). The IPR is mounted in the high pressure pump and achieves injection control pressure regulation by discharging excess oil through a shuttle valve into the front cover and back to sump.

I bought a 2001 F350 a few months back. The gentleman who sold it to me said it didn’t leak oil but it needed new injectors. He was correct as I found lots of oil in the fuel filter. It also stalled at stop signs and at lights randomly while consuming massive amounts of oil due to a bad o-ring on the #7 injector. Lots of oil mixing with the fuel. So I resealed all the injectors with new o-rings, new wiring harness for the injectors and glow plugs, new valve cover gasket, cleaned out the fuel bowl and installed new fuel filter and changed the oil. Took 4 cranking sessions to get it started and when it started it ran like shit until a few minutes later the idle would kind of even out. Well lo and behold, I look in the valley of the engine and the spacer to the IPR valve is just laying there in a small pool of oil. Tinnerman nut nowhere to be found. I’ve got one on the way and hope that after reinstalling the spacer and tin nut I will have the same results as you guys did. Wish me luck

Great video bro❕❕❕You covered like all the sensors that you’d ever need to change accept the cam positions sensor. Thanks good video keep them coming

Hey Guys, Thanks for the video! My Dad and I have been re-habbing a 95 Powerstroke 7.3. We have run into some intermittent issues (no start, stalling, etc). We narrowed the issue down to a bad wiring harness. Upon wiggling wires on bank 2 side, we could duplicate the issue, by means of having the engine shut off. So, we replace the harness with a brand new one. After, running the truck for a full day we are feeling VICTORIOUS and cocky. no more than 10 minutes from HQ, the thing gradually loses power as we coast to the side of the road. Again, we are in that no start state. Sadly, upon running ForeScan, we discover all of the same codes from before the harness replacement. 5-6 codes, mostly related to a short spanning several cylinders on the Bank 2 side. My Pops seems to be convinced our problem is in the IPR, but why would we be getting these same codes? Also, I'll add that our ForeScan seemingly doesn't have the full spectrum of functionality, I'm guessing is due to his PCM being re-programmed. The truck was built in Nov. 94. Any help would be greatly appreciated! Take care!

That was the same problem I had my nut fell off and the spacer fell off both were laying in pool of oil put it back on truck stop stalling and ran awesome thanks

Good vid, having similar issues on my dad truck, swapped the CPS and nothing, gonna check the IPR hope that could be the issue

I need to know what obd2 will-fi module he used I need to stream real time data on a 2000/7.3 diesel PLEASE HELP

How did you get the HPOP and IPR PID(the dials with the labels) on torque pro? I dont see those stats anywhere on my app, I paid for torque pro on android.

Where do you learn diagnostics. How can I find all the numbers I need to know.

Could you tell me how high ore low was your % from IPR when it was broken ?

To determine ipr valve failure disconnect wire and see if it changes, it defaults to set values when disconnected

I'm having issues with my 02 7.3 It starts and drives and randomly when I'm getting into it it wants to spit a sputter it only does it after a rain it's been doing this for a few weeks now any suggestions. My wipers do not affect it in anyway

It's not a shield...that's the solenoid coil that operated the valve to control the HPOP oil pressure read by the IPR sensor located right above the IPR valve in the driver's side head.

When it would die at light would you need to hit it with some starting fluid or did it just back up

What is the loud vibration noise before you turned it on?? Mine does it too

Every 7.3 powerstroke video i see are all automatic trucks.... Is mine the only manual in existence?

Did you say you are using forescan? What’s the pid for hpop preasure called?

Using torque pro app? If so what obd2 connection are you using ?

Mine does the same

My truck is running weird when I give gas with check engine light coming on and I noticed the nut also backed off so you think this is the problem

You don't have to take the fuel bowl off I've changed manny and never removed the fuel bowl

That’s exactly what happened to mine Truck didn’t have 60,000 miles on it 1995 model

Don't buy cheap IPR valves found that out tonight

Really thought this was going to be an instructional class on how to diagnose it. Do you think before speaking?

Liked the diagnostic explanation, but you don’t show any mechanical part changing

My 6.0 will run until it gest up to operating temp and then die. It wont start back up again until its cools off. Anyone know if that could be the ipr getting hot or something?

Having trouble with my truck. Suspected IPR. Just checked and the nut is missing on mine also. Sensor slides all over Hoping that's what my trouble is also.

You look like a pool guy.
