Injection Control Pressure Sensor (ICP)

Injection Control Pressure Sensor

Injection Control Pressure (ICP) Sensor:

The Injection Control Pressure (ICP) sensor is a variable capacitor sensor that is supplied a 5-volt reference signal by the PCM and returns a linear analog voltage signal that indicates pressure. The sensor measures the oil pressure in the high pressure pump cover, and the PCM uses this information to determine injection control pressure. The ICP sensor along with the Injection Control Pressure Regulator form a closed loop fuel pressure control system.

If the PCM detects an inoperative ICP sensor, the PCM will control injection control pressure from a PCM-estimated injection control pressure.
