The Injector Control Pressure sensor, or ICP sensor, is a vital component responsible for monitoring and controlling the high-pressure oil system that drives the fuel injectors in your 7.3-liter Power Stroke engine.. The injector control pressure (ICP) sensor is on both the 7.3L and 6.0L Powerstroke engines. They use a high pressure oil system as a way to pressurize fuel in the injector body. ICP sensors on the Ford 7.3 diesel engines read the oil pressure in the HPOS. This allows the PCM to increase or decrease pressure via the IPR.
Maintaining Your 7.3 Powerstroke ICP Sensor Regular maintenance helps extend the life of your injector control pressure sensor: Inspect electrical connections for corrosion every 12 months Monitor engine performance for early warning signs Keep the engine oil clean and changed according to the manufacturer's schedule Avoid aftermarket HPOP modifications that can overload the sensor A well.. Your icp sensor - 7.3 Injection Control Pressure Sensor - works with the IPR and PCM to control fuel injection pressure. Make sure it's doing it right.
