So I just finished doing a head gasket job and I must have yanked out this little guy somehow. It is coming out of the wire harness at the front of the car, next to the battery. I have no idea what it is or where it came from. Maybe a temperature sensor? Help please

 

looks like one of those plugs behind the front headlights that do nothing..

 

Looks like an ambient temp sensor..

 

It is the ambient temp sensor, it plugs into a little hole on the bottom left of the car, just under the radiator. It's what tells you inside what the temp is outdoors.

 

+1 with 850. Mine clips in the lower air dam.

 

Sounds good, thanks my dudes

 

..lol

 

well i learned something new today.

 

Should mount something like this.

 

That's exactly where mine mounts.
