Cummins ISB CM850 (2003-06) Fault Code: 2292 PID: SPN: FMI: 16 Fuel Inlet Meter Device – Data Valid but Above Normal Operational Range – Moderately Severe Level. The flow demand is higher than expected. Causes of this fault code include the following: High inlet restriction, plugged fuel filter, low lift pump pressure, low resistance to the electronic fuel control actuator, stuck or restricted electronic fuel control actuator, system return (excessive return flow from the injectors, high-pressure pump, or rail pressure relief valve), or tampering. Fault Code 2292 sets when the ECM commands the electronic fuel control actuator to open more...

Cummins ISB CM850 (2003-06) Fault Code: 2293 PID: SPN: FMI: 18 Fuel inlet meter device flow demand lower than expected – data valid but below normal operational range – moderately severe level. The flow demand is lower than expected. Fault Code 2293 is activated when the electronic fuel control actuator is closed more than expected to lower rail fuel pressure. An electric fuel control actuator with excessive leakage can possibly result in high rail fuel pressures at idle or light load. A restriction in the fuel-drain-to-tank return line can prevent unneeded fuel from exiting the high-pressure fuel pump. This excess...

Cummins ISB CM850 (2003-06) Fault Code: 2311 PID: SID 81 SPN: 633 FMI: 11 Fueling Actuator Number 1 Circuit Error Conditions Exists. Fuel pump actuator circuit resistance too high or too low. If this fault code occurs during road test or sea trial, verify that all connectors are clean and free of corrosion before replacing components. This fault code can become active for any of the following reasons: 1)Fuel pump actuator high resistance2)Engine harness high resistance3)Loose, worn, or corroded connectors or pins4)Fuel pump actuator with low internal resistance5)Fuel pump actuator or engine harness that has shorted to ground6)Intermittent circuit failures...

Cummins ISB CM850 (2003-06) Fault Code: 2321 PID: 190 SPN: 190 FMI: 2 Engine Crankshaft Speed/Position – Data Erratic, Intermittent, or Incorrect. Crankshaft engine speed sensor intermittent synchronization. During engine operation, the electronic control module (ECM) monitors the primary speed sensor (crankshaft speed sensor) signal. Fault Code 689 will become active and light the yellow lamp (marine does not use lamps) if the signal from the primary speed sensor is not present or degraded for more than three continuous seconds. Meanwhile, if the primary engine speed sensor signal is not present or is degraded for a moment (less than three...

Cummins ISB CM850 (2003-06) Fault Code: 2322 PID: SID 64 SPN: 723 FMI: 2 Backup Engine Speed/Position Sensor Number 2 – Data Erratic, Intermittent, or Incorrect. Camshaft engine speed sensor intermittent synchronization. During engine operation, the ECM monitors the secondary speed sensor (camshaft speed sensor) signal. Fault Code 778 will become active and light the yellow lamp (marine does not use lamps) if the signal from the secondary speed sensor is not present or degraded for more than three continuous seconds. If over a period of time, the ECM detects several incidents of a loss of the secondary speed sensor...
