P-105: Engine Misfires Or Runs Rough
Probable root causes:* Leaking fuel line* Valve lash* Fuel injection nozzle* Fuel injection pump* Cylinder problem* Intake or exhaust restriction* Fuel supply* Unstable rack motionPerform the following tests in order:1. Inspect and repair any fuel leaks.2. Loosen fuel line nuts one at a time to isolate misfiring cylinder.3. If misfiring cylinder can be isolated: * Check valve lash on misfiring cylinder.* Test injection nozzle on misfiring cylinder.* Check injection pump (plunger and barrel) on misfiring cylinder.* Inspect inside of misfiring cylinder for damage.4. If misfiring cylinder cannot be isolated: * Check intake and exhaust systems for restrictions.* Check fuel pressure.* Check fuel quality (also water or air in fuel)* Check for popping sounds in air intake (adjust valve lash if sounds are heard).* Check for unstable rack motion (refer to P-104: Erratic Or Unstable Engine RPM).P-106: Poor Or No Response To Throttle
Probable root causes:* Active Diagnostic Codes* Throttle control signal* Boost pressure signal* Fuel supply* Air inlet or exhaust restrictions* Inlet air system leaksPerform the following tests in order:1. Troubleshoot any ACTIVE diagnostic codes. * Codes 25 or 42 limit power or rpm or both* Code 32 limits engine speed to low idle* Code 56 may limit engine speed to low idle, depending on which parameter caused the code to be generated2. Verify that engine has shifted out of Cold Mode3. P-211: Throttle Control Sensor Test4. P-224: Boost Pressure Sensor Test5. Inspect fuel system components and check for correct fuel pressure.6. Check the air inlet and exhaust systems for restrictions.P-107: Low Power/Engine RPM Restricted
Probable root causes:* Active Diagnostic Codes* PEEC Self-Checks or Cold Mode (normal operation)* Throttle control signal* Fuel supply restrictions* Inlet air system problems* Exhaust system restrictions* Boost pressure signal* Rack controls* Timing advance (mechanical)Perform the following tests in order:1. Troubleshoot any ACTIVE diagnostic codes and LOGGED Codes * Codes 24 and 46 limit engine speed to 1350 rpm.* Codes 22, 25, 42, and 43 limit engine power.* Code 48 limits engine speed to 1350 rpm in gear even if it is only LOGGED and not ACTIVE.2. Verify that complaint is NOT due to parameters. * Check Top Engine Limit.* Verify that Full Load Setting and Full Torque Setting are programmed to the values stamped on the engine information plate.3. Verify that PEEC has completed its start-up self checks and is out of Cold Mode.4. P-211: Throttle Control Sensor Test5. Check fuel system: * for proper fuel pressure and fuel return flow* for high fuel temperature* for high API reading6. Check for air system problems: * plugged air filter* aftercooler restrictions* aftercooler leaks* high intake air temperature7. Check for exhaust system restrictions.8. P-224: Boost Pressure Sensor Test9. P-230: Dynamic Rack Controls Test10. P-240: Checking Injection Timing and Timing Advance Test11. P-301: Camshaft Timng For Fuel Injection Pump12. Run PAR (Performance Analysis Report) Test.P-110: Intermittent Engine Shutdowns
Use this procedure ONLY if the engine completely shut down and needed to be restarted using the power switch(es). Probable root causes:* Poor Connection* Battery power
