Component Inspection

  1. Ignition "OFF".
  2. Disconnect oil control valve connector.
  3. Measure resistance between power terminal and control terminal of the solenoid connector(Component side).

  4. Is resistance within specification?

    YES 

    • Go to next step as below.

    NO 

    • Check oil control valve for contamination, deterioration, or damage. Substitute with a known-good solenoid and check for proper operation. If the problem is corrected, replace solenoid and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
