Test Procedure

  1. D1 PRELIMINARY DIAGNOSIS 

    Are DTCs P0016, P0315, P0335, P0336 or P1177 present? 

    Yes No
    GO to D2  . For symptoms without DTCs, GO to D2  .
    For all others, RETURN to SYMPTOM CHARTS for further direction.
  2. D2 CHECK THE CKP SENSOR SIGNAL SENT TO THE PCM 
    NOTE: The battery should be fully charged and the starting system should be functioning correctly.
    • Ignition ON, engine OFF.
    • Access the PCM and monitor the RPM (RPM) PID.
    • Crank the engine.

    Is the RPM greater than 150 RPM? 

    Yes No
    For DTCs P0016, P0315, P0335, P0336 or P1177, GO to D3  .
    For all others, The CKP, PCM, and harness are working correctly.
    RETURN to SYMPTOM CHARTS for further direction.    		 GO to D3  .
  3. D3 CHECK FOR VOLTAGE AT THE SENSOR 
    • Ignition OFF.
    • CKP Sensor connector disconnected.
    • Ignition ON, engine OFF.
    • Measure the voltage between:
      (+) CKP Sensor Connector, Harness Side (-) CKP Sensor Connector, Harness Side
      VREF - Pin 1 SIGRTN - Pin 2

    Is the voltage between 4.5 - 5.5 V? 

    Yes No
    GO to D4  . GO to PINPOINT TEST B .
  4. D4 CHECK FOR AN OPEN 
    • Ignition OFF.
    • PCM-E connector disconnected.
    • Measure the resistance between:
      (+) CKP Sensor Connector, Harness Side (-) PCM-E Connector, Harness Side
      CKP - Pin 3 CKP - Pin 33

    Is the resistance less than 5 ohms? 

    Yes No
    GO to D5  . REPAIR the open circuit. Clear the PCM DTCs.
    REPEAT the self-test.
  5. D5 CHECK FOR A SHORT TO GROUND 
    • Measure the resistance between:
      (+) CKP Sensor Connector, Harness Side (-)
      CKP - Pin 3 Ground
    • Measure the resistance between:
      (+) CKP Sensor Connector, Harness Side (-) CKP Sensor Connector, Harness Side
      CKP - Pin 3 SIGRTN - Pin 2

    Are the resistances greater than 10K ohms? 

    Yes No
    GO to D6  . REPAIR the short circuit. Clear the PCM DTCs.
    REPEAT the self-test.
  6. D6 CHECK FOR A SHORT TO VOLTAGE 
    • Ignition ON, engine OFF.
    • Measure the voltage between:
      (+) CKP Sensor Connector, Harness Side (-)
      CKP - Pin 3 Ground

    Is any voltage present? 

    Yes No
    REPAIR the short circuit. Clear the PCM DTCs.
    REPEAT the self-test.    		 GO to D7  .
  7. D7 INTERMITTENT CHECK 
    NOTE: Chafed CKP or camshaft position 11 (CMP11) sensor wires or other physical damage to the harness may cause an intermittent short in the CKP or CMP11 circuit.
    • Ignition OFF.
    • CKP Sensor connector connected.
    • PCM-E connector connected.
    • Visually check for chafed CKP and CMP11 wires or other physical damage to the CKP or CMP11 harness.

    Is a concern present? 

    Yes No
    REPAIR as necessary.
    Clear the PCM DTCs. REPEAT the self-test.    		 For DTC P0016, GO to PINPOINT TEST V .
    For all others, GO to D8  .
  8. D8 CHECK THE PHYSICAL CONDITION OF THE CKP SENSOR 
    • Check the CKP sensor for damage.

    Is the CKP sensor damaged? 

    Yes No
    INSTALL a new CKP sensor. REFER to the service information , Electronic Engine Controls.
    CARRY OUT the Reset And Clear The Specified Function Crankshaft Position Sensor on the scan tool. REFER to CLEAR THE CONTINUOUS DIAGNOSTIC TROUBLE CODES (DTCS) AND RESET THE EMISSION MONITORS INFORMATION IN THE POWERTRAIN CONTROL MODULE (PCM) .
    Clear the PCM DTCs. REPEAT the self-test.    		 GO to D9  .
  9. D9 CHECK THE PHYSICAL CONDITION OF THE IGNITION PULSE CRANKSHAFT SENSOR RING 
    • Check the ignition pulse crankshaft sensor ring for damage.

    Is the ignition pulse crankshaft sensor ring damaged? 

    Yes No
    INSTALL a new ignition pulse crankshaft sensor ring. REFER to the service information , Engine, In-Vehicle Repair, Crankshaft Rear Seal for additional information. GO to D10  .
  10. D10 CHECK FOR SYNCHRONIZATION 
    • Access the PCM and monitor the SYNC (MODE) PID.
    • Crank the engine while viewing the SYNC PID.

    Does the SYNC PID read YES? 

    Yes No
    For DTC P1177, GO to PINPOINT TEST V .
    For all others, GO to D11  .    		 INSTALL a new CKP sensor. REFER to the service information , Electronic Engine Controls.
    CARRY OUT the Reset And Clear The Specified Function Crankshaft Position Sensor on the scan tool. REFER to CLEAR THE CONTINUOUS DIAGNOSTIC TROUBLE CODES (DTCS) AND RESET THE EMISSION MONITORS INFORMATION IN THE POWERTRAIN CONTROL MODULE (PCM) .
    Clear the PCM DTCs. REPEAT the self-test.
  11. D11 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.
