#7.3 injector driver module location free
Luckily, and if you have even an inexpensive ODBII scan tool combined with a free to cheap cell phone app, you can do some further ICP investigation. failed, ICP sensor on your 7.3 is that your engine just won’t start at all.īut, to tell you the truth, so many failed parts on your 7.3 diesel cause the exact same symptoms that it’s hard to tell what’s not working. ICP Sensor 7.3 Location Diagramħ.3 Powerstroke ICP sensor failure symptoms include: Your 7.3 diesel’s ICP sensor is located on the driver’s side cylinder head toward the front of the engine compartment … near the HPOP. Just where is the ICP sensor on a 7.3 Powerstroke, anyway? What will actually happen is that it will get incorrect data from your 7.3 ICP and then deliver incorrect oil pressure, causing at best rough-running and at worst a no-start condition.īut let’s not get ahead of ourselves. If, or should I say when, your 7.3 ICP fails, the PCM in your truck won’t know how much pressure’s in the oil rails and it won’t be able to regulate that pressure to efficiently actuate the injectors, resulting in poor engine performance. 7.3 HPOP – High Pressure Oil PUMP (pump responsible for delivering the physical oil to the oil galleys and thus the oil pressure needed to actuate the injectors and ignite the fuel).7.3 IPR – Injection Pressure REGULATOR (valve that plunges to physically create (regulate) oil pressure).7.3 PCM – Powertrain CONTROL Module (send voltage signals to control oil pressure).7.3 ICP – Injection Control Pressure SENSOR ( measures oil rail pressure in psi).
This analog voltage signal to the PCM tells it how much pressure’s in the oil rails.Īnd in conjunction with the 7.3 IPR, HPOP, and PCM, the Injection Control Pressure Sensor on your 7.3 provides this pressure information feedback in a continuous loop.īroken down and simplified, these are the four components on your 7.3 Powerstroke diesel that regulate oil pressure in order to accurately and efficiently actuate your injectors enabling them to fire and create combustion. It uses a five volt signal and returns it to the PCM. This is so that the PCM can determine how much pressure, at any given second, to deliver to the injectors for maximum fuel firing efficiency.īroken down, the 7.3 Injection Control Pressure sensor tells the PCM what the oil pressure is in the driver’s side oil rail.
In a diesel engine as heavily-reliant on adequate and correct oil pressure as the 7.3 HEUI system is, the 7.3 PCM needs instant and accurate information on the amount of pressure in the 7.3 oil rails. Just what does the ICP sensor on a 7.3 Powerstroke do? When you buy through links on our site, we may earn an affiliate commission. The three of them, along with the 7.3 HPOP, provide enough oil pressure to the oil rails so that when you press on the accelerator, your 7.3 injectors actuate, your engine gets diesel and the cylinders fire … ideally, as smoothly as possible.ĭead Head Diesel is reader-supported. The 7.3 ICP sends the current pressure reading to the Powertrain Control Module (PCM) which in turn signals the 7.3 Injection Pressure Regulator (IPR) to add or reduce pressure. Your ICP sensor – 7.3 Injection Control Pressure Sensor – continuously monitors your diesel engine’s oil delivery pressure.
