Help me ID this sensor

[Inneedofabuick]

Was looking under my car today and noticed a rather large unpluged sensor hanging down by the oil filter area. It has 3 female prongs slots all 90 degrees to one another on opposite sides and a small hole in the middle. I cannot find anywhere to plug it into, Any thoughts?

Thanks
