VTC Oil Control Solenoid Valve Removal

1. Disconnect the VTC oil control solenoid valve 2P connector (A).
2. Remove the bolt (B) and the VTC oil control solenoid valve (C).
3. Check the VTC oil control solenoid valve strainer for clogging. If the strainer is clogged, replace the VTC oil control solenoid valve.

Finally, note the amount of valve opening by observing the position of the piston shoulder (A) through the valve retard drain port. If you see the shoulder of the piston, the valve is open and must be replaced.
