M45 V8-4.5L (VK45DE) (2006)
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 solenoid 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.
