Where the radiator hose attachess to the engine there is a fitting that has 2 vacuum hoses connected to it. I was wondering what that is for.

What year is it? I have an 82, and there are a few sensors on the thermo housing with vac. lines, but none RIGHT by it.

Vacuum Switching Valve (VSV) for the charcol canister should be light blue in color.

its a ported Vacuum Switch. I don't know exactly what it does but I do know its about $50 for a new one from Toyota and no other parts stores I've called have them. they are pretty fragile and break alot. (broke 2 rebuilding my friends motor).
