What does the icp sensor do on a 2001 Ford F-250 with a 7.3 liter diesel?

The ICP (Injection Control Pressure) sensor on a 2001 Ford F-250 with a 7.3-liter diesel engine monitors the oil pressure within the high-pressure oil system that controls the fuel injectors. It provides feedback to the engine control module (ECM) to ensure the correct amount of oil pressure is present for optimal injector operation. If the ICP sensor fails or provides inaccurate readings, it can lead to poor engine performance, hard starting, or stalling issues. Proper functioning of this sensor is crucial for the efficient operation of the diesel fuel injection system.
