You might disconnect it and see what happens to your engine coolant temperature guage on the dash. If it does not affect your dash temperature guage then maybe its a engine knock sensor.

Remember to reconnect the harness back up when your done.

 

well larry thanks for the info i had my wife take what was left of the sensor to a mechanic and he told her it was a knock sensor like u said.i guess u got to trust the older guys lol thanks again

 

Thanks for the feedback Tex. Did the sensor get that way because it was a bitch to get the harness off it?
