Component Inspection: Notes

CHECK OCV AND FILTER 

1. Check resistance of OCV.
   1. Ignition "OFF"
   2. Disconnect intake OCV connector.
   3. Measure resistance between terminals 1 and 2 of the intake OCV connector (Component side).

      Specification:  Approx. 6.9~7.9Ω at 20°C (68°F)

   4. Is resistance within the specification?

      YES 

      • Go to  2.

      NO 

      • Replace OCV and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
2. Check operation of OCV
   1. Start the engine and let it idle.
   2. With OCV connector still disconnected, connect 12V and a ground to 2 and 1 of the OCV (Component side).

      SPECIFICATION: 

      OCV SPECIFICATION
      
      

      Test Condition	Disconnect OCV connector	Apply battery voltage
      Normal Value	Normal engine speed	Rough idle or engine stall

   3. Has a problem been found?

      YES 

      • Go to  3.

      NO 

      • Go to "CHECK CVVT (CONTINUOUSLY VARIABLE VALVE TIMING) ASSEMBLY " procedure.
3. Check OCV and Filter.
   1. Ignition "OFF"
   2. Check OCV filter for sticking or contamination.
   3. Remove the OCV and visually check the spool column of OCV for contamination.
   4. Has a problem been found?

      YES 

      • Clean or replace as necessary and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.

      NO 

      • Go to  5.
   5. Apply 12V and a ground to 2 and 1 terminals of the OCV (Component side).
   6. Verify that a "clicking" sound is heard when applying the battery voltage.
   7. Repeat this procedure 4 or 5 times to ensure intake OCV reliability.

   8. Is OCV working properly?

      YES 

      • Go to CHECK CVVT (CONTINUOUSLY VARIABLE VALVE TIMING) ASSEMBLY .

      NO 

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