INPUT/OUTPUT SIGNAL CHART

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

SYSTEM DESCRIPTION

This mechanism hydraulically controls cam phases continuously with the fixed operating angle of the intake

valve.

The ECM receives signals such as crankshaft position, camshaft position, engine speed, and engine coolant

temperature. Then, the ECM sends ON/OFF pulse duty signals to the intake valve timing (IVT) control sole-

noid valve depending on driving status. This makes it possible to control the shut/open timing of the intake

valve to increase engine torque in low/mid speed range and output in high-speed range.
