Hello all, New to this forum and got the check engine light today. My AAT sensor has a fault. Can anyone tell me where is this sensor is located on a 06 Chrysler 300. It may have been damaged when I hit a deer last winter because it has not been accurate since. It has apparently failed now because I am getting the engine light. Can't find anything in my repair manual that even mentions that it exists. Any help would be appreciated.
