Test Procedure

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2006 Ford RV Cutaway, 2006 Ford Pickup, 2006 Ford F550 Super Duty, 2006 Ford F450 Super Duty, and 2006 Ford Econoline. However, it is still accessible from the selected car via links, so may be relevant.
  1. C1 PRELIMINARY DIAGNOSIS FOR DIAGNOSTIC TROUBLE CODE (DTC) P0830 OR P0833 
    • The DTCs P0830 and P0833 are set if the powertrain control module (PCM) does not detect a CPP switch change of state during the Key On Engine Running (KOER) self-test.
    • Possible causes:
      • clutch pedal not fully applied and released during the self-test
      • signal circuit open or shorted
      • CPP switch
      • PCM
    • Carry out a visual inspection.
    • Retrieve and record any continuous and on-demand DTCs.
    • Clear the DTCs.
    • Carry out the KOER self-test.

    Are DTCs P0830 or P0833 present? 

    Yes No
    For DTC P0830, GO to  C2.
    For DTC P0833, GO to  C7.    		 UNABLE to duplicate the condition. CHECK for a loose connection, and damaged or corroded terminals. WIGGLE the harness attempting to recreate the fault. REPAIR as necessary. REFER to SYMPTOM CHARTS , if a driveability concern exists.
  2. C2 CHECK THE CPP SWITCH FOR VOLTAGE 
    • Key in OFF position.
    • CPP Switch connector disconnected.
    • Key ON, engine OFF.
    • Measure the voltage between:
      ( + ) CPP Switch Connector, Harness Side ( - )
      CPP-BT - Pin 5 Ground

    Is the voltage between 4.5 - 5.5 V? 

    Yes No
    GO to  C3. GO to  C4.
  3. C3 CHECK THE CPP SWITCH GROUND CIRCUIT FOR AN OPEN 
    • Key in OFF position.
    • Measure the resistance between:
      ( + ) CPP Switch Connector, Harness Side ( - )
      GND - Pin 6 Ground

    Is the resistance less than 5 ohms? 

    Yes No
    INSTALL a new CPP switch. CLEAR the DTCs. REPAIR the open circuit. CLEAR the DTCs.
    REPEAT the self-test. REPEAT the self-test.
  4. C4 CHECK THE CPP SIGNAL CIRCUIT FOR AN OPEN 
    • Key in OFF position.
    • PCM connector disconnected.
    • Measure the resistance between:
      ( + ) PCM Connector, Harness Side ( - ) CPP Switch Connector, Harness Side
      CPP-BT - Pin B27 CPP-BT - Pin 5

    Is the resistance less than 5 ohms? 

    Yes No
    GO to  C5. REPAIR the open circuit. CLEAR the DTCs.
    REPEAT the self-test.
  5. C5 CHECK THE CPP SIGNAL CIRCUIT FOR A SHORT TO GROUND 
    • Measure the resistance between:
      ( + ) PCM Connector, Harness Side ( - )
      CPP-BT - Pin B27 Ground

    Is the resistance greater than 10K ohms? 

    Yes No
    GO to  C6. REPAIR the short circuit. CLEAR the DTCs.
    REPEAT the self-test.
  6. C6 CHECK THE CPP SIGNAL CIRCUIT FOR A SHORT TO VOLTAGE 
    • Key ON, engine OFF.
    • Measure the voltage between:
      ( + ) PCM Connector, Harness Side ( - )
      CPP-BT - Pin B27 Ground

    Is any voltage indicated? 

    Yes No
    REPAIR the short circuit. CLEAR the DTCs.
    REPEAT the self-test.    		 GO to  C11.
  7. C7 CHECK THE CPP SWITCH FOR VOLTAGE 
    • Key in OFF position.
    • CPP Switch connector disconnected.
    • Key ON, engine OFF.
    • Measure the voltage between:
      ( + ) CPP Switch Connector, Harness Side ( - )
      VPWR - Pin 3 Ground

    Is the voltage greater than 10.5 V? 

    Yes No
    GO to  C8. REPAIR the open circuit. CLEAR the DTCs.
    REPEAT the self-test.
  8. C8 CHECK THE CPP SWITCH 
    • Key in OFF position.
    • Measure the resistance between:
      ( + ) CPP Switch Connector, Component Side ( - ) CPP Switch Connector, Component Side
      VPWR - Pin 3 CPP-TT - Pin 4
    • Apply and release the clutch pedal.

    Is the resistance less than 5 ohms with the clutch pedal released and greater than 10K ohms with the clutch pedal fully applied? 

    Yes No
    GO to  C9. INSTALL a new CPP switch. CLEAR the DTCs.
    REPEAT the self-test.
  9. C9 CHECK THE CPP SIGNAL CIRCUIT FOR AN OPEN 
    • PCM connector disconnected.
    • Measure the resistance between:
      ( + ) PCM Connector, Harness Side ( - ) CPP Switch Connector, Harness Side
      CPP-TT - Pin B36 CPP-TT - Pin 4

    Is the resistance less than 5 ohms? 

    Yes No
    GO to  C10. REPAIR the open circuit. CLEAR the DTCs.
    REPEAT the self-test.
  10. C10 CHECK THE CPP SIGNAL CIRCUIT FOR A SHORT TO VOLTAGE 
    • Key ON, engine OFF.
    • Measure the voltage between:
      ( + ) PCM Connector, Harness Side ( - )
      CPP-TT - Pin B36 Ground

    Is any voltage indicated? 

    Yes No
    REPAIR the short circuit. CLEAR the DTCs.
    REPEAT the self-test.    		 GO to  C11.
  11. C11 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 and 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.
