Broken sensor?

Noticed a broken sensor or something not quite sure what it is, it's on the rear passenger block behind and below the EGR and looks like it is screwed into the block and has a single wire connector that I assume use to plug into it.

Any ideas?

Thanks

I don't believe that the 2.8l engines have a knock sensor. It is most likely the fan switch (back up for the ECM control of the fan relay).
