OIL CONTROL VALVE (OCV) INSPECTION [SKYACTIV-G 2.0]

Coil Resistance Inspection

1. Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION.)

2. Disconnect the OCV connector.

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

OCV coil resistance

• 6.9—7.5 ohms [20°C {68°F}]

• If not as specified, replace the OCV. (See OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)

4. Install in the reverse order of removal.

Spool Valve Operation Inspection

1. Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION.)

2. Remove the OCV. (See OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)

3. Verify that the spool valve in the OCV is in the maximum valve timing advance position as indicated in the figure.

• If not as specified, replace the OCV. (See OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)

4. Verify that the battery is fully charged. (See BATTERY INSPECTION.)

• If not as specified, recharge the battery. (See BATTERY RECHARGING.)

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. Apply battery positive voltage between the OCV terminals and verify that the spool valve operates and moves to the maximum valve timing retard position.

• If not as specified, replace the OCV. (See OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)

6. Stop applying battery positive voltage and verify that the spool valve returns to the maximum valve timing advance position.

• If not as specified, replace the OCV. (See OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)

7. Install the OCV. (See OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)
