[QUOTE="Mark Price 2, post: 1005470, member: 70403"] Great thought Gavin! I just read on another forum that someone else was reading the 140. I looked in my 03 Ford Wiring Diagram. "Ambient air temperature sensor". Part #19E702. 2 pin Potentiometer. Definitely could be unplugged from the console. ..Looks like you can hook up a voltmeter to a known good ground and stick the other lead right into the sensor. dark blue/yellow wire pin is the feed and the darkblue/white wire pin is the return. I'm guessing (key in run position)it should read between .?millivolts-5volts depending on the temp outside. maybe 2-3volt range? (5volts on feed and 2-3ish on return)Let me know if I can help as I have the wiring diagram. Although, I must admit, I am just started learning how to read them this week. [/QUOTE]
