SYSTEM DESCRIPTION
![Nissan Maxima. SYSTEM DESCRIPTION](/images/manuals/399/nissan_maxima_intake_valve_timing_control_524.jpg)
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 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.
