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 troubleshooting video! I am interested in the Tech Pro app for my 1999 Ford F250 7.3 engine. I clicked on the OBD2 link but when I follow the link, it says "no longer available". Do you have another recommendation for an OBD connect and app for a 7.3 diesel engine?
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
I didnt know this was a possible diagnosis with ipr! Good to know. I knew you could do this with icp. I was unsure so didn't want to hurt it. My truck ended up being the IDM computer.
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.
@@DrivenDiesel Making videos is much tougher than people think...I catch myself saying the wrong thing but don't realize it until I'm editing the video. I figure most of the time people realize what I meant to say rather than what words came out of my mouth.
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
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?
@@DrivenDiesel, I got a good one, if you like to help people, I. plow for my town, plugged in truck last night, fired right up this morning, warmed up, went to get load of sand for sander, starting missing, dead within half hr, has new fuel pump, filter, and I even installed a pressure gauge, icp is only 3mos old, but already leaks, oil is full, truck was purring til this
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.

Any update?! How’d it do?

What is your percentage on ipr percentage during cranking and does it bounce a lot
@@DrivenDiesel around 40%. Doesn't bounce drastically from there
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
To determine ipr valve failure disconnect wire and see if it changes, it defaults to set values when disconnected
Yup! Thats another sign that led us to look into the IPR
@@DrivenDiesel Well you didn't need to diagnose shit if you would have just looked down and realized your IPR was missing Tin nut and magneto ?? LOL
I didnt know this was a possible diagnosis with ipr! Good to know. I knew you could do this with icp. I was unsure so didn't want to hurt it. My truck ended up being the IDM computer.
At this point I’ve disconnected the whole truck and it runs better Everytime 😂
@@user-nr9ob9xy8h this is exactly how I feel with mine lmaoo
Where do you learn diagnostics. How can I find all the numbers I need to know.
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
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.
You're right. Misspeak!
@@DrivenDiesel Making videos is much tougher than people think...I catch myself saying the wrong thing but don't realize it until I'm editing the video. I figure most of the time people realize what I meant to say rather than what words came out of my mouth.
Can you unplug the ipr to try to see if that’s the problem
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
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
Check icp wiring and check icp plug for oil and ipr plug for oil. You really need live data numbers for that problem.
Every 7.3 powerstroke video i see are all automatic trucks.... Is mine the only manual in existence?
Yes. Ford only made one.
Could you tell me how high ore low was your % from IPR when it was broken ?
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?
Hpop leak
LPOP
Using torque pro app? If so what obd2 connection are you using ?
Yes! We used a Bluetooth BAFX
I have the torque pro app with the bafx Bluetooth how do I find the pids you are using for your 7.3
Tons of videos out there. You have to add the Ford PIDs
@@DrivenDiesel, I got a good one, if you like to help people, I. plow for my town, plugged in truck last night, fired right up this morning, warmed up, went to get load of sand for sander, starting missing, dead within half hr, has new fuel pump, filter, and I even installed a pressure gauge, icp is only 3mos old, but already leaks, oil is full, truck was purring til this
What is the loud vibration noise before you turned it on?? Mine does it too
That RUMP? My truck does it also but just that one initial fire not twice.
H-pop ?
Really thought this was going to be an instructional class on how to diagnose it. Do you think before speaking?
Nah lol
When it would die at light would you need to hit it with some starting fluid or did it just back up
It would just start back up for me
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
60k?! Woah! Thats a low mileage OBS. What have you done to it?
Did you say you are using forescan? What’s the pid for hpop preasure called?
Nvm just seen u said torquepro
We used both to validate!
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
Did it fix it?
This sounds like a CPS ( crank position sensor )
Don't buy cheap IPR valves found that out tonight
ICP and IPR, ALWAYS go motorcraft. Can't emphasis this enough. Aftermarket sensors are low quality
Liked the diagnostic explanation, but you don’t show any mechanical part changing
That was the point of the video. There are a ton of videos that show the mechanical part
How much is this repair and how long does it take to complete?
@@DrivenDiesel how long to replace with all new parts
@@jtrentvines ipr takes about an hour tops
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.
Fix it?
@@stitchthisditchthat259 I did. Shop vacuum in the valley and found the nut. Running great again
@@stephenbrandner5059 how was your truck running when this happened
@@weekendwarriors9502 it would miss a few times then usually shut off. After pulling over and turning off ignition it would fire right back up.
Mine does the same
You look like a pool guy.
