OIL CONTROL VALVE (OCV) INSPECTION [L5]

Coil Resistance Inspection

1. Disconnect the negative battery cable.

2. Remove the plug hole plate. Service and Repair

3. Disconnect the OCV connector.

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






OCV coil resistance
- 6.9-7.9 ohms [20°C {68°F}]

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

5. Install in the reverse order of removal.

Spool Valve Operation Inspection

1. Remove the OCV. Oil Control Valve (OCV) Removal/Installation

2. 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

3. Verify that the battery is fully charged. Testing and Inspection

- If not as specified, recharge the battery. Procedures

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





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. Oil Control Valve (OCV) Removal/Installation

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. Oil Control Valve (OCV) Removal/Installation

6. Install the OCV. Oil Control Valve (OCV) Removal/Installation
