Component Tests and General Diagnostics

OIL CONTROL VALVE (OCV) INSPECTION

Coil Resistance
1. Disconnect the OCV connector.





2. Inspect for continuity between terminals A and B using an ohmmeter.
^ If not as specified, replace the OCV.

Specification (20°C (68°F)) 6.9 - 7.9

Spool Valve Operation
1. Remove the OCV.





2. Verify that the spool valve in the OCV is the maximum valve timing retard position.
^ If not as specified, replace the OCV.

3. Verify that the battery is fully charged.
4. Apply battery positive voltage between the OCV terminals and verify that the spool valve operates and moves to the maximum valve timing advance position.
^ If not as specified, replace the OCV.

Note:
^ When applying battery positive voltage between the OCV terminals, the connection can be either of the following:
- Positive battery cable to terminal A, negative battery cable to terminal B.
- Positive battery cable to terminal B, negative battery cable to terminal A.





5. Stop applying battery positive voltage and verify that the spool valve returns to the maximum valve timing retard position.
^ If not as specified, replace the OCV.
