问：您好，我有一个丰田Prius混合动力车2003，我在发动机上检查了，它没有蛇形腰带，并且已经运行了

我的Toyota Prius 2003没有蛇形腰带，它一直以这种方式运行。But when I looked in there the camshaft isn’t spinning I was wondering if it would spin once a put the belt on and if it had a sensor or something to get it to start again or if that means I have another problem I tried running the ac or heater to see if maybe it would move then or spin but it doesn’t .

我的汽车有150000英里。
我的汽车有自动变速箱。
