Test Procedure

WARNING: This page is about a different car, the 2013 Ford F-550 Super Duty, 2013 Ford F-450 Super Duty, 2013 Ford F-350 Super Duty, and 2013 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
  1. ME1 CHECK FOR DTCS 

    Are DTCs P0001, P0002, P0003, P0004, P0089, P0090, P0091 or P0092 present? 

    Yes No
    GO to ME2  . For an engine no start concern, GO to ME2  .
    For all others, if no DTCs are retrieved, the system is operating correctly at this time. The concern may be intermittent. CHECK for a loose connection, and damaged or corroded terminals. WIGGLE the harness attempting to recreate the concern. REPAIR as necessary.
    RETURN to ENGINE CONTROLS - SYMPTOM CHARTS (DIESEL) , Symptom Charts for further direction.
  2. ME2 CHECK THE VPWR CIRCUIT FOR VOLTAGE 
    • Ignition OFF.
    • Fuel Pressure Control Valve Solenoid connector disconnected.
    • Fuel Volume Control Valve Solenoid connector disconnected.
    • Ignition ON, engine OFF.
    • Measure the voltage between:
      (+) Fuel Pressure Control Valve Solenoid Connector, Harness Side (-)
      VPWR - Pin 1 Ground
    • Measure the voltage between:
      (+) Fuel Volume Control Valve Solenoid Connector, Harness Side (-)
      VPWR - Pin 1 Ground

    Are the voltages greater than 10.5 V? 

    Yes No
    GO to ME3  . REPAIR the open circuit. Clear the PCM DTCs. REPEAT the self-test.
  3. ME3 CHECK THE FPCV AND FVCV CIRCUITS FOR AN OPEN 
    • Ignition OFF.
    • PCM-E connector disconnected.
    • Measure the resistance between:
      (+) Fuel Pressure Control Valve Solenoid Connector, Harness Side (-) PCM-E Connector, Harness Side
      FPCV - Pin 2 FPCV - Pin 3
    • Measure the resistance between:
      (+) Fuel Volume Control Valve Solenoid Connector, Harness Side (-) PCM-E Connector, Harness Side
      FVCV - Pin 2 FVCV - Pin 22

    Are the resistances less than 5 ohms? 

    Yes No
    GO to ME4  . REPAIR the open circuit. Clear the PCM DTCs. REPEAT the self-test.
  4. ME4 CHECK THE FPCV AND FVCV CIRCUITS FOR A SHORT TO GROUND 
    • Measure the resistance between:
      (+) Fuel Pressure Control Valve Solenoid Connector, Harness Side (-)
      FPCV - Pin 2 Ground
    • Measure the resistance between:
      (+) Fuel Volume Control Valve Solenoid Connector, Harness Side (-)
      FVCV - Pin 2 Ground

    Are the resistances greater than 10K ohms? 

    Yes No
    GO to ME5  . REPAIR the short circuit. Clear the PCM DTCs. REPEAT the self-test.
  5. ME5 CHECK THE FPCV AND FVCV CIRCUITS FOR A SHORT TO VOLTAGE 
    • Ignition ON, engine OFF.
    • Measure the voltage between:
      (+) Fuel Pressure Control Valve Solenoid Connector, Harness Side (-)
      FPCV - Pin 2 Ground
    • Measure the voltage between:
      (+) Fuel Volume Control Valve Solenoid Connector, Harness Side (-)
      FVCV - Pin 2 Ground

    Is any voltage present? 

    Yes No
    REPAIR the short circuit. Clear the PCM DTCs. REPEAT the self-test. GO to ME6  .
  6. ME6 CHECK THE FUEL PRESSURE CONTROL VALVE SOLENOID AND FUEL VOLUME CONTROL VALVE SOLENOID RESISTANCE AT THE COMPONENT 
    • Ignition OFF.
    • Measure the resistance between:
      (+) Fuel Pressure Control Valve Solenoid Connector, Component Side (-) Fuel Pressure Control Valve Solenoid Connector, Component Side
      FPCV - Pin 2 VPWR - Pin 1
    • Measure the resistance between:
      (+) Fuel Volume Control Valve Solenoid Connector, Component Side (-) Fuel Volume Control Valve Solenoid Connector, Component Side
      FVCV - Pin 2 VPWR - Pin 1

    Are the resistances between 2 - 6 ohms? 

    Yes No
    GO to ME7  . INSTALL a new Fuel Pressure Control Valve or Fuel Volume Control Valve as necessary. REFER to the appropriate Electronic Engine Controls article.
    Clear the PCM DTCs. REPEAT the self-test.
  7. ME7 CHECK THE FUEL PRESSURE CONTROL VALVE SOLENOID AND FUEL VOLUME CONTROL VALVE SOLENOID FOR A SHORT TO GROUND 
    • Measure the resistance between:
      (+) Fuel Pressure Control Valve Solenoid Connector, Component Side (-)
      FPCV - Pin 2 Ground
    • Measure the resistance between:
      (+) Fuel Volume Control Valve Solenoid Connector, Component Side (-)
      FVCV - Pin 2 Ground

    Are the resistances greater than 10, 000 ohms? 

    Yes No
    GO to ME8  . INSTALL a new Fuel Pressure Control Valve or Fuel Volume Control Valve as necessary. REFER to the appropriate Electronic Engine Controls article.
    Clear the PCM DTCs. REPEAT the self-test.
  8. ME8 CHECK FOR CORRECT PCM OPERATION 
    • Disconnect all the PCM connectors.
    • Visually inspect for:
      • pushed out pins
      • corrosion
    • Connect all the PCM connectors and make sure they seat correctly.
    • Carry out the PCM self-test.
    • Verify the concern is still present.

    Is the concern still present? 

    Yes No
    INSTALL a new PCM. REFER to FLASH ELECTRICALLY ERASABLE PROGRAMMABLE READ ONLY MEMORY (EEPROM) . The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
