Test Procedure

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2004 Ford RV Cutaway, 2004 Ford Pickup, 2004 Ford F550 Super Duty, 2004 Ford F450 Super Duty, and 2004 Ford Excursion. However, it is still accessible from the selected car via links, so may be relevant.
  1. D1 PRELIMINARY DIAGNOSIS FOR DTCS P0335, P0336, P2617 
    NOTE: Some DTCs require that the engine go through more than one key cycle to set.
    NOTE: DTCs P0336 and P2617 are calibrated to an increment counter. To set a DTC requires greater than 5 consecutive fault events in the crank mode or 10 fault events in the run mode. Perform the required number of key cycles from RUN to START to RUN (cycling to OFF will reset timer) and then perform the KOEO or KOER self-test.
    • Perform the visual inspection.
    • Connect the scan tool.
    • Retrieve and record all DTCs.
    • Clear all DTCs.
    • Perform the KOEO on-demand self-test.
    • Perform the KOER on-demand self-test.

    IS DTC P0335, P0336 OR P2617 PRESENT? 

    Yes No
    For DTCs P0335 or P0336: Go to  D2.
    For DTC P2617, Go to  D8.    		 Unable to duplicate condition. CHECK for loose connection, damaged or corroded terminals or pins. WIGGLE harness attempting to recreate the fault. REPAIR as necessary. REFER to SYMPTOM CHARTS - 6.0L DIESEL if a driveability concern exists. REFER to DIAGNOSTIC SUBROUTINES - 6.0L DIESEL , to diagnose a no-start condition.
  2. D2 DIAGNOSTIC TROUBLE CODE (DTC) P0335, P0336 
    NOTE: Refer to the PCM and component connector pin numbers, Figure,Figure and Figure, at the beginning of this pinpoint test.
    • Possible causes:
      • one or both sensor outputs open
      • one of both sensor outputs shorted to ground
      • sensor outputs shorted together
      • one output open and the other output shorted to ground
      • sensor output shorted to voltage
      • CKP sensor
      • PCM

    DOES THE ENGINE START? 

    Yes No
    Go to  D3. REFER to DIAGNOSTIC SUBROUTINES - 6.0L DIESEL , to diagnose no-start condition.
  3. D3 CHECK THE RESISTANCE OF THE CKP SENSOR 
    • Key off.
    • Disconnect the PCM engine harness connector.
    • Measure the resistance between PCM engine harness connector pin 30 and pin 41.

    IS THE RESISTANCE BETWEEN 300 AND 400 OHMS? 

    Yes No
    Go to  D5. Go to  D6.
  4. D5 CONFIRM PCM FAULT 
    NOTE: Some DTCs require that the engine go through more than one key cycle to set.
    • Key on.
    • Reconnect all electrical connectors.
    • Key on.
    • Clear all DTCs.
    • Perform the KOEO on-demand self-test.
    • Perform the KOER on-demand self-test.

    IS DTC P0335, P0336 OR P2617 PRESENT? 

    Yes No
    INSTALL a new PCM. RESTORE the vehicle. CLEAR DTCs and RETEST the system. Unable to duplicate the condition. CHECK for loose connection, damaged or corroded terminals or pins. WIGGLE harness attempting to recreate the fault. REFER to SYMPTOM CHARTS - 6.0L DIESEL if a driveability concern exists.
  5. D6 CHECK CKP CIRCUITS FOR A SHORT TO GROUND 
    • Disconnect the CKP sensor.
    • Inspect the CKP sensor for damaged or corroded pins.
    • Measure the resistance between PCM engine harness connector as follows:
      • pin 30 and ground
      • pin 41 and ground
      • pin 30 and pin 42
      • pin 41 and pin 42

    ARE THE RESISTANCES GREATER THAN 10,000 OHMS? 

    Yes No
    Go to  D7. REPAIR short in CKP sensor circuit. RESTORE the vehicle. CLEAR DTCs and RETEST the system.
  6. D7 CHECK CKP SENSOR CIRCUITS FOR AN OPEN 
    • Measure the resistance between the PCM engine harness connector pin 30 and CKP sensor harness connector pin 1; and PCM engine harness pin 41 and CKP sensor harness connector pin 2.

    ARE THE RESISTANCES LESS THAN 5 OHMS? 

    Yes No
    INSTALL a new CKP sensor. RESTORE the vehicle. CLEAR DTCs and RETEST the system. REPAIR open circuit. RESTORE the vehicle. CLEAR DTCs and RETEST the system.
  7. D8 DIAGNOSTIC TROUBLE CODE (DTC) P2617 
    NOTE: Refer to the PCM, FICM and component connector pin numbers, Figure, Figure and Figure, at the beginning of this pinpoint test.
    NOTE: Some DTCs require that the engine go through more that one key cycle to set.
    NOTE: DTCs P2617 and P2614 may set simultaneously after an engine stalling event. Note: DTCs P0336 and P2617 are calibrated to an increment counter. To set a DTC requires greater than 5 consecutive fault events in the crank mode or 10 fault events in the run mode. Perform the required number of key cycles from RUN to START to RUN (cycling to OFF will reset timer) and then perform the KOEO or KOER self-test.
    • Possible causes:
      • signal shorted to voltage
      • signal shorted to ground
      • signal circuit open
      • PCM
    • Perform the KOEO on-demand self-test.
    • Perform the KOER on-demand self-test.

    IS DTC P2617 PRESENT? 

    Yes No
    Go to  D9. Unable to duplicate condition. CHECK for loose connections, damaged or corroded pins. WIGGLE harness attempting to recreate fault. REFER to SYMPTOM CHARTS - 6.0L DIESEL if a driveability concern exists.
  8. D9 CHECK CRANKSHAFT POSITION SIGNAL CIRCUIT FOR A SHORT TO VOLTAGE 
    • Key off.
    • Disconnect the PCM engine harness connector.
    • Disconnect the FICM harness connector C.
    • Key on.
    • Measure the voltage between FICM harness connector C pin 5 and ground.

    IS THE VOLTAGE LESS THAN 0.2 VOLTS? 

    Yes No
    Go to  D10. REPAIR short to voltage. RESTORE the vehicle. CLEAR DTCs and RETEST the system.

    • Key off.
    • Measure the resistance between FICM harness connector C pin 5 and ground.

    IS THE RESISTANCE GREATER THAN 10,000 OHMS? 

    Yes No
    Go to  D11. REPAIR short to ground in signal output circuit. RESTORE the vehicle. CLEAR DTCs and RETEST the system.
  10. D11 CHECK CRANKSHAFT POSITION SIGNAL CIRCUIT FOR AN OPEN
