Verify the electronic control module (ECM) calibration is correct. Check the calibration revision history found on QuickServe™ Online for applicable fixes to the calibration stored in the ECM. If necessary, recalibrate the ECM. A fuel pump actuator with excessive leakage or a damaged inboard o-ring will result in high fuel rail pressures at idle or light load. If the fuel pump actuator exhibits excessive leakage, it is possible that the fuel rail pressure will reach the opening pressure of the fuel rail pressure relief valve and Fault Code 1911 can possibly also become active. The fuel rail pressure sensor should...

Verify the electronic control module (ECM) calibration is correct. Check the calibration revision history found on QuickServe™ Online for applicable fixes to the calibration stored in the ECM. If necessary, recalibrate the ECM. This fault code can become active any time the engine is loaded and the electronic control module (ECM) detects the fuel pressure in the rail fuel is not changing. This fault code will become inactive whenever the ECM is powered down or if the ECM detects that the engine is loaded and the fuel pressure is changing normally. If there are many inactive counts of this fault...

Verify the electronic control module (ECM) calibration is correct. Check the calibration revision history found on QuickServe® Online for applicable fixes to the calibration stored in the ECM. If necessary, recalibrate the ECM. Use the following procedure in the corresponding Troubleshooting and Repair Manual for the engine being serviced. Possible causes: 1)Crankcase ventilation filter needs to be replaced2)Crankcase pressure sensor damage3)Malfunctioning or misassembled closed crankcase ventilation valve4)Frozen, plugged, or restricted crankcase ventilation hose5)Plugged or restricted crankcase ventilation hose6)Plugged or restricted crankcase ventilation oil drain tube or check valve7)Plugged or restricted crankcase breather tube (Rear Engine Mounted Crankcase Ventilation Filter)8)High air...
