Test Procedure

  1. HD1 CHECK FOR DTCS 

    Is DTC P0300, P0301, P0302, P0303, P0304, P0315, or P0316 present? 

    Yes No
    For DTC P0315, GO to  HD18.
    For all others, GO to HD2  .    		 For symptoms without DTCs, GO to HD2  .
    For all others, RETURN to SYMPTOM CHARTS for further direction.
  2. HD2 VIEW THE PCM MISFIRE FREEZE FRAME DATA 
    NOTE: The misfire freeze frame data may be used to determine the operating conditions when the misfire DTC was set.
    • Retrieve and record any available misfire freeze frame data PID values from the PCM.
    • Compare recorded freeze frame data PID values to the typical reference values in REFERENCE VALUE .

    Are any values out of range? 

    Yes No
    REFER to the TABLE  in Pinpoint Test Z to find corresponding circuit, and PROCEED with the intermittent diagnosis.
    GO to PINPOINT TEST Z .    		 GO to HD3  .
  3. HD3 RELATIVE COMPRESSION TEST 
    NOTE: The IDS test referenced in this step may not be available on all vehicles. Follow the YES answer if the IDS test is not available.
    • Carry out the Relative Compression Test. Refer to the instruction manual provided by the scan tool manufacturer.

    Do all cylinders pass the test? 

    Yes No
    GO to HD4  . CARRY OUT a cylinder compression test on the suspect cylinder. REFER to the appropriate article, Engine System.
  4. HD4 CHECK FOR OTHER NON-MISFIRE CONTINUOUS MEMORY DTCS 
    • Retrieve the PCM continuous memory DTCs.

    Are there any non-misfire continuous memory DTCs present? 

    Yes No
    DISREGARD the current diagnostic trouble code (DTC) at this time. DIAGNOSE the next DTC. GO to DIAGNOSTIC TROUBLE CODE (DTC) CHARTS AND DESCRIPTIONS . GO to HD5  .
  5. HD5 CHECK FOR ANY KOEO DTCS 
    • Carry out the PCM KOEO self-test.

    Are any KOEO DTCs present? 

    Yes No
    DISREGARD the current diagnostic trouble code (DTC) at this time. DIAGNOSE the next DTC. GO to DIAGNOSTIC TROUBLE CODE (DTC) CHARTS AND DESCRIPTIONS . GO to HD6  .
  6. HD6 CHECK FOR ANY KOER DTCS 
    • Carry out the PCM KOER self-test.

    Are any KOER DTCs present? 

    Yes No
    DISREGARD the current diagnostic trouble code (DTC) at this time. DIAGNOSE the next DTC. GO to DIAGNOSTIC TROUBLE CODE (DTC) CHARTS AND DESCRIPTIONS . GO to HD7  .
  7. HD7 CYLINDER POWER BALANCE TEST 
    NOTE: The IDS test referenced in this step may not be available on all vehicles. Follow the YES answer if the IDS test is not available.
    • Carry out the Power Balance Test. Refer to the instruction manual provided by the scan tool manufacturer.

    Are all cylinders contributing correctly during the power balance test? 

    Yes No
    GO to  HD9. GO to HD8  .
  8. HD8 CHECK THE IGNITION SYSTEM FOR CONCERNS 

    Is an ignition related concern present? 

    Yes No
    REPAIR as necessary.
    Clear the PCM DTCs. REPEAT the self-test.    		 GO to HD9  .
  9. HD9 RELATIVE INJECTOR FLOW TEST 
    NOTE: The IDS test referenced in this step may not be available on all vehicles. Follow the YES answer if the IDS test is not available.
    • Carry out the Relative Injector Flow Test. Refer to the instruction manual provided by the scan tool manufacturer.

    Are all injectors flowing correctly? 

    Yes No
    GO to HD10  . CHECK for a loose connection, and damaged or corroded terminals. REPAIR as necessary.
    GO to HD10  .
  10. HD10 CHECK THE FUEL SYSTEM FOR CONCERNS 

    Is a fuel system related concern present? 

    Yes No
    REPAIR as necessary.
    Clear the PCM DTCs. REPEAT the self-test.    		 GO to HD11  .
  11. HD11 CHECK THE VACUUM SYSTEM 
    NOTE: Some vacuum leaks can be heard.
    • Visually inspect the vacuum hoses for signs of damage or deterioration. A collapsed vacuum hose may cause a blockage to one of the various actuators or sensors. If a blockage is found remove the blockage or install new parts as necessary.

    Is the vehicle vacuum system OK? 

    Yes No
    GO to HD12  . REPAIR the vacuum system.
    Clear the PCM DTCs. REPEAT the self-test.
  12. HD12 MONITOR THE ELECTRIC EXHAUST GAS RECIRCULATION (EEGR) SYSTEM RELATED PIDS 
    • Ignition ON, engine running.
    • Bring the engine to normal operating temperature.
    • Access the PCM and monitor the EGRMC1F (MODE), EGRMC2F (MODE), EGRMC3F (MODE) and EGRMC4F (MODE) PIDs.
    • Access the PCM and monitor the MAP (VOLT) PID.
    • Record the PID values with the engine idling.
    • Ignition ON, engine OFF.
    • Record the PID values with the engine off.
    • Compare recorded freeze frame data PID values to the typical reference values in REFERENCE VALUE , Reference Values.

    Are any values out of range? 

    Yes No
    GO to PINPOINT TEST KD . GO to HD13  .
  13. HD13 RECREATE THE MISFIRE SYMPTOM WITH EEGR SYSTEM DISABLED 
    NOTE: The PCM may store EGR system related DTCs during this procedure.
