If not as specified, replace the oil control valve. (SeeOIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION [LF].)
Oil control valve resistance
6.9—7.9 ohms [20°C {68°F}]
1. Remove the battery cover.
2. Disconnect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION [LF].)
3. Disconnect the oil control valve connector.
4. Measure the resistance between terminals A and B using an ohmmeter.
If not as specified, replace the oil control valve. (SeeOIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION [LF].)
Oil control valve resistance
6.9—7.9 ohms [20°C {68°F}]
5. Connect the oil control valve connector.
1. Remove the battery cover.
2. Disconnect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION [LF].)
3. Remove the oil control valve.
4. Verify that the spool valve in the oil control valve is in the maximum valve timing retard position as indicated in the figure.
If not as specified, replace the oil control valve. (SeeOIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION [LF].)
5. Verify that the battery is fully charged.
If not as specified, recharge the battery. (See BATTERY INSPECTION [LF].)
6. Apply battery positive voltage between the oil control valve terminals and verify that the spool valve operates and moves to the maximum valve timing advance position.
If not as specified, replace the oil control valve.
NOTE:
When applying battery positive voltage between the oil control valve 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 oil control valve.
