What is the difference between CVT and VVT?

CVT: continuous variable transmission. with this you can have infinite gear ratios. VVT : Variable valve timing. It is used for engines where you can change the lift timing for valves of an engine(intake/exhaust) at high engine speeds.

Correspondingly, what does the VVT sensor do?

Most parts are non-serviceable and have integrated sensors. On a conventional engine, exhaust and intake valves are open or closed depending on the crankshaft and the pattern cannot be altered. With VVT, it is possible to have the timing altered to match the engine speed, torque requirements, and valve overlap.

What is dual VVT I engine?

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.
