In the most miserable place to get a wrench to! Follow the lower radiator hose back to the engine block. It should be right UNDER the throttle body/air inlet. There are two 10mm bolts securing the two parts of the housing. Remove the temperature sensor, then remove the two 10mm bolts. You can leave the bolt with the ground leads attached. The lower rear bolt is a nightmare to reach but it can be done. Good luck.
