P2283
Injector Control Pressure Sensor Circuit
A general electrical fault on the injector control pressure (ICP) sensor — used on HEUI (Hydraulically actuated Electronically controlled Unit Injector) systems on heavy-duty diesel engines such as the Ford Powerstroke 6.0/7.3 and Caterpillar engines. ICP measures the high-pressure oil that actuates the injectors.
