P2289 Dodge Code - Injector Control Pressure Too High Engine Off
Quick Answer
The Powertrain Control Module (PCM) monitors the Injector Control Pressure (ICP) sensor. Common causes include Faulty Injector Control Pressure (ICP) sensor, Injector Control Pressure (ICP) sensor harness is open or shorted, Injector Control Pressure (ICP) sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2289 Dodge Description
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.
