P2290 Description

The Powertrain Control Module (PCM) monitors the Injector Control Pressure (ICP) sensor. The code sets when the signal from the sensor is out of factory specifications, and the PCM will go to open loop control of injection control pressure (operate from an estimated injection control pressure).

The ICP sensor is a variable capacitance sensor that, when supplied with a 5-volts reference signal from the PCM, produces a linear analog voltage signal that indicates pressure.

The ICP sensor's primary function is to provide a feedback signal to indicate rail pressure so that the PCM con command the correct injector timing and pulse width and the correct injection control pressure for the proper fuel delivery at all speed and load conditions.
