Test Procedure

WARNING: This page does not describe the selected car, but rather 30 other vehicles, including the 2004 Mercury Sable, 2004 Mercury Mountaineer, 2004 Mercury Monterey, 2004 Mercury Marauder, and 2004 Mercury Grand Marquis. However, it is still accessible from the selected car via links, so may be relevant.
  1. TA1 DTC P0704: CHECK THE CPP SWITCH 
    CAUTION: Apply vehicle Park Brake.

    Ensure that the vehicle is secured with wheel chocks  .

    • NOTE: During self-test, the clutch pedal must be down and gearshift lever in NEUTRAL.
    • Key OFF.
    • Connect the scan tool.
    • Key ON Engine OFF.
    • Select the CPP PID and monitor for an ON/OFF PID state while performing the following:
    • - Press and release the clutch pedal several times.

    Did the reading cycle when the CPP switch was activated? 

    Yes No
    Suspect an intermittent circuit fault
    Inspect connectors for signs of damage, water ingress, corrosion, etc. REPAIR as necessary.    		 GO to  TA2.
  2. TA2 CHECK THE SWITCH CIRCUIT RESISTANCE 
    • Switch location(s):
    • The CPP switch is located near the clutch pedal.
    • INSPECT the switches and brackets for damage. Repair as necessary.
    • CPP connector disconnected.
    • Measure the resistance between:
      ( + )CPP Connector, Component Side ( - )CPP Connector, Component Side
      CPP SIGRTN
    • Measure the CPP switch resistance with the clutch pedal down.

    Is the resistance less than 5 ohms? 

    Yes No
    GO to  TA3. REPLACE the
    CPP
  3. TA3 CHECK THE CPP FOR INTERNAL SHORTS 
    • CPP connector disconnected.
    • Measure the resistance between:
    ( + )CPP Connector, Component Side ( - )CPP Connector, Component Side
    CPP SIGRTN
    • Measure the CPP switch resistance with the clutch pedal UP.

    Is the resistance less than 5 ohms? 

    Yes No
    REPLACE the CPP. GO to  TA4.
  4. TA4 CHECK THE CPP AND SIGRTN CIRCUIT(S) FOR AN OPEN IN THE HARNESS 
    NOTE: REFER to the POWERTRAIN CONTROL MODULE (PCM) CONNECTOR  in the beginning of this pinpoint test.
    • PCM connector disconnected.
    • Measure the SIGRTN resistance.
    • Measure the resistance between:
    ( + )PCM Connector, Harness Side ( - )CPP Connector, Harness Side
    CPP CPP
    SIGRTN SIGRTN

    Are the resistances less than 5 ohms? 

    Yes No
    GO to  TA5. REPAIR the open circuit.
  5. TA5 CHECK CIRCUIT FOR SHORT TO POWER 
    • Measure the voltage between:
    ( + )CPP Connector, Harness Side ( - )12V vehicle battery
    CPP Negative terminal

    Is the voltage less than 1 V? 

    Yes No
    GO to  TA6. REPAIR the short to power in the circuit
  6. TA6 CHECK THE CPP CIRCUIT FOR A SHORT TO GROUND IN THE HARNESS 
    • Measure the resistance between:
    ( + )PCM Connector, Harness Side ( - )
    CPP Ground

    Is the resistance greater than 10K ohms? 

    Yes No
    REPLACE the PCM. REFER to FLASH ELECTRICALLY ERASEABLE PROGRAMMABLE READ ONLY MEMORY - FLASH EEPROM REPAIR the short circuit.
