What is the name of the part of the EGR Valve with the screw in needle that has a wire connected to it ?

 

I think you are referring to the EGR temp switch. Senses if hot gas is moving past it indicating EGR is functioning, which is "watched' by the ECM.

Mine isn't a needle though, just a squared off end.

Thats it ya theres like a needle point that screws in to that piece. When i took mine out it broke so now that I know what it is i can buy thank you.

 

Needlepoint? I thought this was an auto enthusiasts' forum, not a crafters' forum. If you want to get into stiching, quilting, and candlemaking, try MarthaStewart.com.

As I recall, there is a blunt ended temperature switch that screws into this location, and it didn't look like any needle to me:
