P-305: No Or Poor Response To Throttle
Probable root causes:* Active Diagnostic Codes* PEEC III Self-Checks or Cold Mode (normal operation)* Progressive Shift Parameters (normal operation)* Throttle position signal* Rack subsystem* Vehicle speed signalPerform the following tests in order:1. Troubleshoot any ACTIVE diagnostic codes.2. Verify that PEEC III has completed its startup self-checks and is out of cold mode.3. Check Progressive Shift Parameters to verify that they are not the cause of the complaint.4. P-502: Throttle Position Sensor Test5. P-521: Rack Position Sensor Test6. P-523: Rack Solenoid (BTM) Test7. P-504: Vehicle Speed Signal TestP-306: Low Power/Engine RPM Restricted/Will Not Reach VSL
Probable root causes:* Active Diagnostic Codes* Customer Parameters (normal operation)* PEEC III Self-Checks or Cold Mode (normal operation)* Throttle position signal* Fuel supply restrictions* Inlet air system problems* Exhaust system restrictions* Boost pressure signals* Rack controls* Timing advance* Vehicle speed signalPerform the following tests in order:1. Troubleshoot any ACTIVE or LOGGED diagnostic codes. * Code 24, 46, and 48 limit engine speed to 1350 rpm.* Code 36 limits engine speed to "Engine RPM At VSL".* Codes 22, 23, 25, 43, 44 limit engine power.2. Verify that the complaint is NOT due to parameters. * Check Progressive Shift Parameters, Vehicle Speed Limit, and 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 III has completed its startup self-checks and is out of cold mode.4. P-502: Throttle Position Sensor Test5. Check for proper fuel pressure/fuel return flow.6. Check for air system problems: * Plugged air filter* Aftercooler restrictions* Aftercooler leaks* High intake air temperature7. Check for exhaust system restrictions8. P-514: Boost Pressure Sensor Test9. P-520: Dynamic Rack Controls Test10. P-533: Dynamic Injection Timing Test11. P-504: Vehicle Speed Signal TestP-307: Cruise Or PTO Does Not Function
Probable root causes:* Active Diagnostic Codes* Customer Parameters (normal operation)* Cruise/PTO Switches* Vehicle speed signalPerform the following tests in order:1. Troubleshoot any ACTIVE diagnostic codes.2. Check High/Low Cruise Limit and Vehicle Speed Calibration.3. P-505: Cruise Control and PTO Switches Test4. P-506: Service Brake and Clutch Switches Test5. P-504: Vehicle Speed Signal TestP-308: Intermittent Engine Shutdowns
Use this procedure ONLY if the engine shut down completely and had to be restarted using the keyswitch. Probable root causes:* Poor connection* Battery power or ground to ECM (vehicle wiring)* After Market engine protection devices (PEEC III does not have engine protection shutdown feature)* Fuel supply* Shutoff solenoid* Shorted 8 volt sensor supply voltage* Rack controls* Engine speed sensor* ECM or Personality ModulePerform the following steps in order:1. Check external PEEC III wiring harness and connectors (refer to P-500: Inspecting Electrical Connectors): * ECM (J4/P4) and Vehicle (J7/P7) connectors.* Transducer connector (J5/P5)* Rack solenoid connector (J3/P3)* Shutoff solenoid connector (J13/P13)2. P-501: Electrical Power Supply Test3. Check for correct installation and operation of engine protection devices.4. P-513: Shutoff Solenoid5. Check fuel tanks and lines for foreign objects which may block fuel supply.6. Bypass OEM wiring and shutdown devices for testing (refer to P-501: Electrical Power Supply
