Note

• When applying battery positive voltage between the oil control valve terminals, the connection of the positive and negative cables can be either terminal A or B.

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

• If there is any malfunction, replace the oil control valve.
