Toyota Tech Articles

Just stumbled across this site which has a lot of info on tech articles covering the basics to Toyota engines, electronics, etc, which a newb like me needs all the help I can get. I need info on my ERG and it seemed to be a helpful website. Haven't delved too deep into yet but I hope it helps. The articles are from Toyota Motor Sales so they seem to be manufacturer provided docs.
