Component Inspection

Check OCV resistance
1. IG "OFF" and disconnect OCV connector.
2. Measure resistance between power and signal terminals of OCV. (Component Side)
  1. Specification: 6.7 ~ 7.7 Ω

3. Is the measured resistance within specification?
  YES
  1. Go to "OCV Actuation Test" as follows.
  NO
  1. Substitute with a known - good OCV and check for proper operation.
    If the problem is corrected, replace OCV and go to VERIFICATION OF VEHICLE REPAIR procedure.

OCV Actuation Test
1. Connect scan tool and IG "ON".
2. Select "OCV" on the Actuation Test.
3. Activate "OCV" by pressing "STRT (F1)" key.
  (should hear a faint click from Oil Control solenoid Valve)
4. Repeat this procedure 4 or 5 times to ensure intake valve control solenoid reliability

5. Does OCV generate click sound during actuation test?
  YES
  1. Substitute with a known - good PCM and check for proper operation. If the problem is corrected, replace PCM and go to VERIFICATION OF VEHICLE REPAIR procedure.
    NOTE: There is a memory reset function on scan tool that can erase optional parts automatically detected and memorized by PCM. Before or after testing PCM on the vehicle, use this function to reuse the PCM on the others
  NO
  1. Substitute with a known - good OCV and check for proper operation. If the problem is corrected, replace OCV and go to VERIFICATION OF VEHICLE REPAIR procedure.
