What is the top speed of a 2003 Nissan Maxima?
According to Car and Driver magazine, "the top speed of a 2003 Nissan Maxima is uncertain, but it is drag limited at 147 mph." The 2003 Nissan Maxima Owner's Manual lists a top speed of 135 mph.
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!
