Help! What sensor is this?

[Quick Red Head]

I'm doing a swap and I need to swap this sensor, and it has a gasket on it. Does anyone know what sensor this is?

The pictures aren't the best, sorry about that. The sensor is located on the driver side of the engine, to the left of the starter.

Thanks

Hey is that the ACIS surge tank in his pic? The same ACIS surge tank that someone told me I couldn't see regardless if I look above or under the engine?

Yep that's a vac can. I don't know who told you you couldn't see it, but you can from the side looking kind of sideways.

lol, yup, that's it. If you want that good of a look, I hope your head fits between the intake and strut tower.
