By looking at your vin you don't have a US car and your sensors are in a different place. Do you have a/c?

ok so the top circle sensor is a temp gauge sensor (Just one terminal on it right? It's called B13) and it should go to termainal 4 of the plug x26 (which is behind the fuse box so I would look for a loose wire before removing it)

The vacuum valve is the item 79 on the first page of this pdf:
