OBD II Fault Code

  • OBD II P2288

    OBD-II Code Engine may not start is defined as a Injector Control Pressure Too High

    Some diesel engines use high pressure oil to control the fuel injectors on the diesel engine. The Injector Pressure Regulator (IPR) regulates the oil pressure going to the injectors. The Injector Control Pressure (ICP) Sensor monitors the oil pressure produced by the high pressure oil pump. If the ICP sends back an implausible signal, code P2288 will be set.
