Intake Sensor name, can't find replacement part picture? on 2005 Dodge Neon

What is the three wire sensor on the plastic intake towards the passenger side. It had oil on the end of it, it has two screws. The little bit of oil was from the pvc tube. What does this sensor do?

maybe it is the intake vacuum sensor, it senses engine load
