    (to Camshaft Position Sensor (for Intake Camshaft))

    HINT: 

    Make sure that the connector is properly connected. If it is not, securely connect it and check for DTCs again.

    1. Disconnect the camshaft position sensor (for intake camshaft) connector.
    2. Turn the power switch on (IG).
    3. Measure the voltage according to the value(s) in the table below.

      Standard Voltage

      Tester Connection Condition Specified Condition
      C51-3 (VC) - Body ground Power switch on (IG) 4.5 to 5.5 V
      C51-1 (VVI+) - Body ground Power switch on (IG) 3.0 to 5.0 V
    4. Turn the power switch off and wait for at least 30 seconds.
    5. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition
      C51-3 (VC) - C51-1 (VVI+) Power switch off 1.425 to 1.575 kΩ
      C51-2 (VVI-) - Body ground Always Below 1 Ω

      Result

      Proceed to
      OK
      NG

    Result: 

    NG 

    See step  4

    Result: 

    OK 

    See step  2

    *a Clearance
    1. Visually check the camshaft position sensor (for intake camshaft) for damage.
    2. Check the camshaft position sensor (for intake camshaft) installation condition.

      OK

      The camshaft position sensor (for intake camshaft) does not have any damage and is installed properly.

      Result

      Proceed to
      OK
      NG

    Result: 

    NG 

    SECURELY REINSTALL CAMSHAFT POSITION SENSOR (FOR INTAKE CAMSHAFT). Refer to  INSTALLATION [06/2018 - ] 

    Result: 

    OK 

    See step  3

  3. INSPECT INTAKE CAMSHAFT (TIMING ROTOR) 
    1. Check the timing rotor of the intake camshaft.

      OK

      Camshaft timing rotor does not have any cracks or deformation.

      HINT: 

      Perform "Inspection After Repair" after replacing the intake camshaft.

      Refer to INITIALIZATION [06/2018 - 07/2019] , or refer to INITIALIZATION [07/2019 - 08/2020]

      Result

      Proceed to
      OK
      NG

    Result: 

    OK 

    REPLACE CAMSHAFT POSITION SENSOR (FOR INTAKE CAMSHAFT). Refer to  REMOVAL [06/2018 - ] 

    Result: 

    NG 

    REPLACE INTAKE CAMSHAFT. Refer to  REMOVAL [06/2018 - 08/2021] 

  4. CHECK HARNESS AND CONNECTOR (CAMSHAFT POSITION SENSOR (FOR INTAKE CAMSHAFT) - ECM) 
    1. Disconnect the camshaft position sensor (for intake camshaft) connector.
    2. Disconnect the ECM connector.
    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition
      C51-1 (VVI+) - C88-90 (VV1+) Always Below 1 Ω
      C51-2 (VVI-) - C88-89 (VV1-) Always Below 1 Ω
      C51-3 (VC) - C88-88 (VCV1) Always Below 1 Ω
      C51-1 (VVI+) or C88-90 (VV1+) - Body ground and other terminals Always 10 kΩ or higher
      C51-2 (VVI-) or C88-89 (VV1-) - Body ground and other terminals Always 10 kΩ or higher
      C51-3 (VC) or C88-88 (VCV1) - Body ground and other terminals Always 10 kΩ or higher

      Result

      Proceed to
      OK
