What does this temp sensor do?
Take a look at the pic below. I was working on my 3.0 V6 and saw it on the back of the intake manifold with the other coolant sensors. There was one line coming off of it, but when I pulled on it it broke off. It looks like the bottom nipple has been broken off for a while. Does anyone know what this sensor is? Should I find another one or should I just put it back in and plug the valc lines?

Broke mine when I was doing the head gasket too its called the "bimetal switching vacuum valve." Not exactly sure what it does but I would replace it if I was you.
Found this that Mudhippy posted
"BVSV(Bimetallic Vacuum Switching Valve).
Is it connected to the hose that goes to the charcoal canister(EVAP) and the other hose going to the throttle body? If so, it regulates the flow of the vapors collected in the canister to the intake. It opens allowing flow when the engine is running warm enough to handle the enrichment. And closes when the engine cools, at which point the charcoal canister absorbs the excess vapors from the fuel tank for later use."

IIRC it costs about $170 at the dealer. I had to buy one for my old 3.0 and ended up breaking the new one while installing it. If you can find both nipples just superglue it, that's what I resorted to.

Do I really need it to run correctly? It seems like I could just plug the side that goes to the intake and call it good. What do you guys think?

Should just be for emissions. Mine ran fine without it but the guys at emissions station noticed the hose dangling from the charcoal canister and wouldn't pass me until it was repaired. If you replace it, try junkyards first like drmix said, I just didn't have any luck with mine.

Plus you'll be filling the air all of us breath with raw gasoline.

I wonder how it would run if I just connected the intake to the canister and bypassed the sensor? Do you think it would idle rough until it warmed up? Has anyone tried that?
