Coil Resistance Inspection

1.Disconnect the negative battery cable.

2.Remove the plug hole plate. (See PLUG HOLE PLATE REMOVAL/INSTALLATION [L5].)

3.Disconnect the OCV connector.

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

• If not as specified, replace the OCV. (See OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION [L5].)

5.Install in the reverse order of removal.

Spool Valve Operation Inspection

1.Remove the OCV. (See OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION [L5].)

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. (See OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION [L5].)

3.Verify that the battery is fully charged. (See BATTERY INSPECTION [L5].)

• If not as specified, recharge the battery. (See BATTERY RECHARGING [L5].)

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

• If not as specified, replace the OCV. (See OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION [L5].)

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. (See OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION [L5].)

6.Install the OCV. (See OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION [L5].)
