  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.
