Just trying to thanks the peolple who create these thread/ forum. Today I found the problem on my daugther's 2003 dodge neon. I have been looking for about 1 1/2 months. Even brought the vehicle to the gararge. The code was ambient air temperature sensor high. Auto parts stores and dodge dealer said there were no listing for an ambient air temperarure sensor for a 2003 dodge neon. Go figure. If the on board computer said there is a trouble code with the ambient air temperature sensor then there must be one somewhere. Anyway like one gentleman on this forum said, it was the same as the intake air temperature sensor and it was located in the front bumber on the driver's side. Thanks to this forum I am a happy camper.

 

Welcome to the iste. I will move this thread to the Neon section,

It took care of your code? I know there was a TSB for Ambient Air Temp sensors erroneous codes.
