OK someone really needs to know this, I found the ambient air temperature sensor inside the front grill. Why do dodge dealers insist that this part does not exist. I have it in my hand right now. its reads on the code PO71 yet they say a 2003 dodge neon does not have this part and its not listed in the parts catalog. WHAT DO I DO NOW? I want to stop the check engine light from coming on but I can't get the part. PLEASE HELP. I know someone out there has purchased one. How about a part number? or a place that actually list the part. I checked the online stores and none of them list it, can I have a car that had this installed as a mistake if so why does the code read that its bad. It should not have even been in the computer.
