    Hi. I have a 2009 Prius. The Yellow Triangle and check engine light has just come on. The engine starts and runs yet the power seems sluggish. Ive noticed the Pwr, Eco and EV mode button's do nothing and the dash "Power Flow" scematic doesnt show any power moving between the engine , battery or wheels. Ive checked the 12v battery and its fully charged and not wet etc. What should i check next? Can it be driven ?

    Is it a NZ new or a Japanese import? Can you post a photo of it, if possible?
