Don Ridley Posted March 13, 2017 Share Posted March 13, 2017 The ECU knows there is no way it is 68 deg in Frisco this time of year ? Quote Link to comment Share on other sites More sharing options...
jrm223 Posted April 7, 2017 Share Posted April 7, 2017 I know that myself and at least one other person here has had that sensor go bad. Mine was replaced under warranty, but they had my van for 2.5 days because the tech assigned to it had a day off the first full day that it was in...

MLB Posted September 3, 2020 Share Posted September 3, 2020 42k on mine and not so much as a sniffle. Nothing but praise here. Quote Link to comment Share on other sites More sharing options...
jrm223 Posted September 3, 2020 Share Posted September 3, 2020 My original one went bad around 33K, had it replaced and now I rolled 124K the other day and no problems. But, the AAT sensor is - or at least was - a common issue among other models because they're all the same unit. I'm wondering if there was a big batch that was bad or just poor manufacturing by the 3rd-party manufacturer that supplies them to Ford.

gwbasley Posted December 29, 2020 Share Posted December 29, 2020 I had the same problem...but I didn't know it. My A/C was intermittent so I took it my local trustworthy shop. They couldn't figure it out and suggested the (not so trustworthy) dealer. I spent days searching on line, saw the ambient air sensor mentioned several times. For $9 I took a shot and, Bingo! That was at 30K miles. Now at 36K and having a new round with ABS/Hill Start Assist failure. Again, I'm trying to avoid the crooked dealership.
