Cummins ISB4.5 CM2150 Fault Code: 554 PID: SPN: 157 FMI: 2 Injector Metering Rail 1 Pressure – Data Erratic, Intermittent, or Incorrect.
Posted by PerDiezel Solutions on
Circuit DescriptionThe fuel pressure sensor contains supply, signal, and return pins. The engine control module (ECM) provides 5 volt to the fuel pressure sensor. This 5 volts power supply is a shared supply. Other sensors on this circuit are the intake manifold temperature/pressure sensor, barometric air pressure sensor, and the backup engine position sensor. Component LocationThe fuel pressure sensor is located in the rail fuel on the air intake side of the engine. Conditions for Running the DiagnosticsThis diagnostic runs continuously when the engine is running. Conditions for Setting the Fault CodesThe ECM detects that the fuel rail pressure reading...
Cummins ISB4.5 CM2150 Fault Code: 555 PID: 101 SPN: 101 FMI: 16 Crankcase Pressure – Data Valid but Above Normal Operating Range – Moderately Severe Level.

Circuit DescriptionThe pressure inside the crankcase filter is measured by the crankcase pressure sensor. When the crankcase pressure sensor determines that the crankcase pressure is higher than normal, this fault code is logged. Component LocationThe crankcase pressure sensor is located near the crankcase ventilation filter. Conditions for Running the DiagnosticsThis diagnostic runs continuously when the engine speed is greater than 500 rpm. Conditions for Setting the Fault CodesThe ECM detects that the crankcase pressure is greater than a calibrated value. Action Taken When the Fault Code is Active-The ECM illuminates the amber CHECK ENGINE light when the crankcase pressure limit...

Circuit DescriptionThe pressure control loop relies on fuel pressure supplied to the high-pressure pump by the fuel gear pump. The engine control module (ECM) monitors rail fuel pressure and engine operating conditions and changes the flow command to maintain the proper rail fuel pressure. Changes to the flow command result in opening (or closing) of the fuel pump actuator to supply more (or less) fuel to the high-pressure pump. Component LocationThe high-pressure fuel pump is mounted to the gear housing on the intake side of the engine. Conditions for Running the DiagnosticsThis diagnostic runs continuously when the engine is operating....
