Coil resistance inspection

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

• If not as specified, replace the OCV.

OCV coil resistance

6.9—7.9 ohms [20 °C {68 °F}]

2.Connect the OCV connector.

Spool valve operation inspection

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

• If it exceeds the specification, replace the OCV.

2.Verify that the battery is fully charged.

• If it is less than specification, recharge the battery.

3.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 it exceeds the specification, 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

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

• If it exceed the specification, replace the OCV.
