Oil Control Valve (OCV) Inspection

OIL CONTROL VALVE (OCV) INSPECTION [LF]

Coil Resistance Inspection

1. Remove the battery cover. Removal and Replacement

2. Disconnect the negative battery cable. Removal and Replacement

3. Disconnect the OCV connector.

4. Measure the resistance between terminals A and B using an ohmmeter.

- If not as specified, replace the OCV. Oil Control Valve (OCV) Removal/Installation

Oil control valve resistance
- 6.9-7.9 ohms [20°C {68°F}]





5. Connect the OCV connector.

Spool Valve Operation Inspection

1. Remove the battery cover. (See Removal and Replacement.)

2. Disconnect the negative battery cable. Removal and Replacement

3. Remove the OCV.

4. Verify that the spool valve in the OCV is in the maximum valve timing retard position as indicated in the figure.

- If not as specified, replace the OCV. Oil Control Valve (OCV) Removal/Installation





5. Verify that the battery is fully charged.

- If not as specified, recharge the battery. Testing and Inspection

6. 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





7. 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.
