Test Procedure

2021 Ford Transit-350 HD Base, Van Cargo Extended, 3.5L Eng VIN 8, AWDSECTION Test Procedure
WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2018 Ford Transit-350 HD, 2018 Ford Transit-350, 2018 Ford Transit-250, 2018 Ford Transit-150, and 2018 Ford F-550 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
  1. D1 PRELIMINARY DIAGNOSIS 

    Are DTCs P0016, P0315, P0335, P0336, P0339, P061C, P1177 or P262A 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, P0339, P061C, P1177 or P262A, GO to  D3.
    For all others, The CKP, PCM, and harness are operating 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 SIGRTN

    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 CKP

    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 Ground
    • Measure the resistance between:
      (+) CKP Sensor Connector, Harness Side (-) CKP Sensor Connector, Harness Side
      CKP SIGRTN

    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 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 DTC P061C, GO to  YA4.
    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
    For Transit, INSTALL a new CKP sensor. REFER to the appropriate Electronic Engine Controls article.
    Clear the PCM DTCs. REPEAT the self-test.
    For all others, INSTALL a new CKP sensor.
    REFER to the appropriate Electronic Engine Controls article.
    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 appropriate Engine System article, In-Vehicle Repair, Crankshaft Rear Seal for additional information. For all others, 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
    GO to PINPOINT TEST V . GO to PINPOINT TEST ZZ .

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
