How to check the PCV valve and hose on Toyota Sienna?

To test the PCV valve, detach the hose, remove the valve, and then reconnect. Inspect for vacuum at the valve opening while the engine is idling. Also, if there's no vacuum, inspect for a clogged hose or valve and replace it. Detach the valve, and blow through it from the cylinder head end. If air doesn't pass, you should replace the valve.
