It is a variable valve timing innovations from Toyota, where in power and fuel efficiency can be optimized by varying the timing of the camshaft with respect to the crankshaft of an engine,by retarding or advancing the camshaft by a certain phase angles.A conventional engine has it's camshaft rotate half the crankshaft rotation and the performance of a such engine would be in it's peak efficiency for a single speed only.Engineers developed a technology to overcome this in-efficiencies by introducing variable valve timing where camshaft rotation can advance or retard with respect to the crankshaft,hence optimising performance and fuel efficiency.

It works simple. You pull the trigger.
It works as the principle according to Newton's second law of motion
vvti timing

Yes. 03 Sienna should have a VVTI engine ( a 1MZ FE with vvti ) which is an interference engine and the valves will hit the piston if it snaps at higher RPM. Pre 01 Siennas have non VVTI 1MZ FE motors, and those are non-interference, therefore safe.
p1349 refers to the variable valve timing, the computer sets this code when it commands the vvti control valve to apply oil pressure to the vvti assembly on the front of the intake camshaft to adjust cam timing and there is no change. the couse could be low or dirty oil, a bad vvti controll oil valve , stopped oil passages , the vvti assembly on the front of intake cam or a bad ecm.

50/50 water/coolant
its the throttle position sensor
EFI, you cannot beat EFI over VVTI
2jzgte (Turbo) or 2jzge (Non Turbo) vvti engine
Hi, It's a VVTi motor! It has 1,4cc and 1,6cc editions!
I think it is a timing belt i have 2001 rav4 1az-fe 2.0 vvti
