Where is the Ambient air temperature sensor located on a Nissan maxima?

I have a 2003 Maxima SE. The ambient air temp sensor is yellow and it is located inside the grill under the hood latch - between the round bells for the horn. You will need a pair of plyers to hold the top of the yellow piece and a small flat screwdriver to push the little tab that hold the two parts of it together. Good Luck!
