    Fault Code 2372

    Fuel Filter Differential Pressure - Data Valid But Above Normal Operating Range -
    Moderately Severe Level

    CODES REASON EFFECT

    Fault Code: 2372 Fuel Filter Differential Pressure - Possible reduced engine performance.
    PID(P), SID(S): P95 Data Valid But Above Normal
    SPN: 95 Operational Range - Moderately
    FMI: 0/16 Severe Level. Excessive fuel flow
    Lamp: Amber restriction to the high pressure
    SRT: fuel pump has been detected.

    ISX11.9 CM2250/ISB6.7 CM2250/ISC8.3 and ISL9 CM2250/ISX15 CM2250 - Electronic Control Module (ECM)

    Circuit Description:
    The engine control module (ECM) monitors engine operating conditions, including the reading of fuel rail pressure,
    and changes the flow command to either increase (OPEN the fuel pump actuator) or decrease (CLOSE the fuel pump
    actuator) the fuel supply to the high-pressure pump.

    Component Location:
    There are two fuel filters and several original equipment manufacturer (OEM) supplied components that can impact
    this fault code. The pressure-side fuel filter is typically mounted directly to the engine, but can also be remote
    mounted. The suction-side fuel filters and other OEM supplied components are OEM specific. The OEM is required to
    supply a suction-side filter, and the exact filter location is OEM dependent. Refer to the OEM service manual.

    Conditions for Running the Diagnostics:


    This diagnostic runs continuously when the engine is running.

    Conditions for Setting the Fault Codes:


    Fuel pressure was less than a calibratible value during high fuel flow conditions indicating a fuel inlet restriction.

    Action Taken When the Fault Code is Active:
    • The ECM illuminates the amber CHECK ENGINE lamp immediately when the diagnostic runs and fails.

    Conditions for Clearing the Fault Code:


    • To validate the repair, perform a key cycle, start the engine and let it idle for 1 minute.
    • The fault code status displayed by INSITE™ electronic service tool will change to INACTIVE immediately after the
    diagnostic runs and passes.
    • The ECM will turn off the amber CHECK ENGINE lamp immediately after the diagnostic runs and passes.
    • The Reset All Faults command in INSITE™ electronic service tool can be used to clear active and inactive faults, as
    well as extinguish the MIL for OBD applications.

    Shop Talk:
    Low fuel pressure at rated speed/load indicates a fuel inlet restriction or a plugged pressure-side fuel filter. Possible
    causes of this fault code include:
    • A plugged pressure or suction side fuel filter
    • Collapsed fuel inlet lines
    • An obstructed suction tube in the fuel tank
    • Plugged fuel tank vents.
    • Malfunctioning high-pressure fuel system
    Note: The mounting location of the suction side fuel filter will vary by OEM, and can possibly not be in an obvious
    location.

    Refer to Troubleshooting Fault Code 2372.
