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.
