VVT-i, or Variable Valve Timing with intelligence, is an automobile variable valve timing technology developed by Toyota. The Toyota VVT-i system replaces the Toyota VVT offered starting in 1991 on the 5-valve per cylinder 4A-GE engine. The VVT system is a 2-stage hydraulically controlled cam phasing system.
Similar to VVT-i, Dual VVT-i adds in control of the exhaust camshaft to the VVT-i's control of intake valves. This is found in the latest-generation V6 engines, starting with the 2GRFE in the 2005 Avalon in the U.S. It is now the most common VVT system in use by Toyota, appearing in most of the LR, UR, GR, AR and ZR engine families.
P1349 Toyota Description Variable Valve Timing (VVT) system controls the intake valve timing to proper timing in response to driving condition. The Engine Control Module ( ECM ) controls Oil Control Valve (OCV) to make the intake valve timing properly, and, oil pressure controlled with OCV is supplied to the VVT controller, and then, VVT ...
A Comparison of the Toyota VVT system Vs the Honda V-TEC. On this page I talk about the two different methods used to increase the power output, and what's good and bad about them. What the two systems are, and why they are used

6. VVT-i (Variable Valve Timing-intelligent) System General This system controls the intake camshaft valve timing so as to obtain balance between the engine output, fuel consumption and emission control performance. The actual intake side valve timing is feed back by means of the camshaft position sensor for constant control to the target valve ...

Let's see how Toyota’s VVT-i system works. The VVT system shown in the video above is a variation of Toyota’s VVT-i, though Honda has a similar system called VTC.
VVT-i, or Variable Valve Timing with intelligence, is an automobile variable valve timing technology developed by Toyota, similar to the i-VTEC technology by Honda. The Toyota VVT-i system replaces the Toyota VVT offered starting in 1991 on the 4A-GE 20-Valve engine.
