Spool Valve Operation Inspection

1.Verify that the spool valve inside the oil control valve is at the maximum valve timing retard position as shown in the figure.

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

2.Apply battery positive voltage between the oil control valve terminals A and B and verify that the spool valve operates and move to the maximum valve timing advance position.

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

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.
