This is the vtti pully TSB = i ended up just buying the vtti cam gear and got toyota to put it on the part was 179.00 and labor to put in on was 195.00 at toyota dealership. Make sure u ask to see if they have done a few of them because if they have most of the mechinics can do it with just taking the valve cover off. Its not easy to do so dont try it urself it controls the engines timing.
It fixed my problem with my check engine light and track control light coming on. I had 60,000 miles on mine its a 06. Some dealerships might warranty it for u if u can find a dearlership that will work with u. U have to pay a 100 dollar diagnoistic charge tho.
