Diagnostic Test

  1. CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE-I

    1. Turn ignition switch OFF.
    2. Disconnect intake valve timing control solenoid valve harness connector.
    3. Check resistance between intake valve timing control solenoid valve terminals as follows.
      Terminals Resistance (Ω)
      1 and 2 7.0 - 7.7 [at 20°C (68°F)]
      1 or 2 and ground
      (Continuity should not exist)

    Is the inspection result normal?

    YES 

    GO TO STEP 2  .

    NO 

    Replace malfunctioning intake valve timing control solenoid valve. Refer to EXPLODED VIEW .

  2. CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE-II

    1. Remove intake valve timing control solenoid valve. Refer to EXPLODED VIEW .
    2. Provide 12 V DC between intake valve timing control solenoid valve terminals 1 and 2, and then interrupt it. Make sure that the plunger moves as shown in the figure below.

      CAUTION:

      Do not apply 12 V DC continuously for 5 seconds or more. Doing so may result in damage to the coil in intake valve timing control solenoid valve.

      NOTE:

      Always replace O-ring when intake valve timing control solenoid valve is removed. 

    Is the inspection result normal?

    YES
