VTC System Diagram
The VTC oil control solenoid valve controls oil pressure to the advance chamber/retard chamber of the VTC actuator
according to a signal from the ECM/PCM. When the VTC actuator vanes rotate to the advance or retard position, the
intake camshaft timing is changed.
CMP sensor A detects the intake camshaft angle and sends the information to the ECM/PCM. The ECM/PCM controls
the VTC oil control solenoid valve as the intake camshaft angle changes.
