So if you’re experiencing rough idle or no start conditions, try unplugging the ICP sensor harness. When there’s no signal from your 7.3 ICP the PCM will use a default signal.

However, it’s geared more toward professional mechanics than us driveway guys and by the time you pay for it, you could get a new IPR and test to see if it was the culprit. There’s a handy tool you can use to check if your 7.3 IPR is bad or if it’s another component in your 7.3 HPOP or high pressure oil delivery system. If the oil is close to the top, the problem could be a bad or failing 7.3 IPR. You can also remove the HPOP Reservoir inspection plug/fill port (scroll down to step #9 on that article) and check the oil level.

If not, your problem may be in your high pressure oil system. If you have a basic scan tool that will check the ICP pressure when you are starting your engine, make sure it generates the minimum pressure-500psi. Check to make sure no oil is seeping from around the IPR, signaling that your 7.3’s IPR o-ring may have failed.

Obviously, a visual inspection of the 7.3 IPR where it screws into the HPOP would be in order. If your 7.3 Powerstroke engine has any of the above-mentioned symptoms, you’ll need a way to troubleshoot it. If that happens the spacer and 7.3 IPR Solenoid will come off and your diesel engine will die. Yet another specific symptom is a result of the Tinnerman nut coming loose. Once your engine does restart, it’ll run and then idle until it shuts down. Your 7.3 Powerstroke won’t sputter to a stop, it’ll just shut down and won’t start again unless you apply a lot of throttle. Then your 7.3 diesel engine will start idling roughly and then it’ll shut off with no warning. When your truck does start, you’ll be able to rev the engine and then idle okay for a few minutes. Your 7.3 diesel will start sometimes and not others. Some specific 7.3 bad IPR symptoms Your 7.3’s IPR may be stuck

Long crank/start times – hard start when the engine’s hotĬareful though, many 7.3 Powerstroke IPR symptoms cause the same bad behavior in your diesel as a failing ICP, a leaking 7.3 HPOP, bad valve cover harnesses and even a bad IPR or ICP pigtail.

Random surging due to low power to the IPR.

Poor, rough, or unstable Idle, especially when you let off the accelerator.

IPR – Injection Pressure REGULATOR (valve that plunges to physically create (regulate) pressure)ħ.3 IPR Symptoms Common symptoms of a bad 7.3 Powerstroke IPR.

PCM – Powertrain CONTROL Module (send voltage signals to control what’s going on).

7.3 ICP – Injection Control Pressure SENSOR ( measures oil pressure).

So, even simpler… And believe me I’ve had a tough time understanding it until I boiled it down for myself: The amount of pressure is controlled by the ICP – Injection Control Pressure sensor and the PCM – Powertrain Control Module – varying ICP pressure by adjusting the IPR duty cycle-add pressure or dump pressure. It’s a valve that interprets electrical signals from the PCM and turns them into actual physical hydraulic pressure in the 7.3 diesel’s high-pressure HEUI oil system.

In short, the 7.3 Powerstroke Injection Pressure Regulator controls the high-pressure oil pump’s outlet pressure. Helps Seal in IPR valve body created HPOP oil pressure. Seals the IPR valve body to the oil channel, holding the pressure in the HPOP. NOTE: This is a 7.3 Common Leak Location and one of the first places to check if your 7.3 HPOP is leaking. When the IPR is screwed into the HPOP this forms the seal between the 7.3 IPR and the 7.3 HPOP. 7.3 IPR SpacerĪllows the IPR to have its required length. The Tinnerman, or “tin nut” as it’s commonly called, is a 1/2″ x 20 fine threaded nut. Is a thin sheet metal retaining nut designed to hold the 7.3 Injection Pressure Regulator solenoid in Place. Here’s a detailed diagram of all the parts on a 7.3 Injection pressure regulator. 7.3 IPR – Injection Pressure Regulator Parts And the 7.3 HPOP is located under the fuel filter housing. Your 7.3 Powerstroke’s IPR is located in the center of the engine compartment, screwed into the lower right rear of your high pressure oil pump-HPOP.
