System summary



*: This signal is sent to the ECM via the CAN communication line



This system hydraulically controls cam phases repeatedly with the addressed operating angle of the intakevalve.

The ECM receives signals such together crankshaft position, camshaft position, engine speed, and also engine coolanttemperature. Then, the ECM sends ON/OFF pulse duty signal to the entry valve timing (IVT) manage solenoidvalve relying on driving status. This renders it possible to regulate the shut/open time of the intakevalve to boost engine speak in low/mid speed variety and calculation in high-speed range.
