Mine is acting up (jumping from 100 ºF to -40 ºF in a matter of seconds). Before I replace it, i want to do some plug jiggling/reseating.

I know the part number is 65-81-6-905-133 but can't for the life of me figure out where it actually is on the car. Any ideas?

 

iirc, it is up behind the front bumper on the passenger side.

 

It's on the back side of your front bumper.

Take the bumper off and you'll see it attached right away

 

it is up behind the front bumper on the passenger side.

 

Yep, passenger side. On my 2011 it stuck out on the bottom of the front lip, easy to spot.
