Component Inspection_1: Notes

■ Check OCV and Filter

Check resistance of OCV
1. Ignition "OFF".
2. Disconnect intake OCV connector.
3. Measure resistance between power and control terminals of OCV. (Component Side)
  Specification : Approx. 6.9~7.9Ω at 20°C (68°F)
4. Is resistance within the specification?
  YES
  - Go to next step as indicated below.
  NO
  - Replace OCV and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.

Check operation of OCV

Start the engine and let it idle.

With OCV connector still disconnected, apply 12V to power terminal and connect ground to control terminal of the OCV (Component side).

Specification:

OCV SPECIFICATIONS

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

Has a problem been found?
YES
- Go to next step as indicated below.
NO
- Go to CHECK CVVT (CONTINUOUSLY VARIABLE VALVE TIMING) ASSEMBLY procedure .

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 next step as indicated below.
5. Apply 12V to power terminal and connect ground to control terminal 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 next step as indicated below.
  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.
