Hi guys, doing an engine swap and during extracting the engine from the engine bay, a sensor on the driver's side next to the exhaust manifold but on the fire wall side got broken in the process. The engine that's going in also has the same sensor broken. Does anyone know what this sensor I called? I have attached a photo.

 

what engine?

 

My apologies, it's the 4.2L V6

 

Cylinder head temp

 

Thank you so so much. I really appreciate it!!!
