Cobra37 Posted December 30, 2018 Report Share Posted December 30, 2018 My outside air temperature is stuck at 50 degrees. Occasionally, in really cold weather it will go to 20 degrees, but after I start the car, it returns to 50. I have read in other searches, that it can be reset, replacing the sensor won't fix the problem, and Ford is no help. Any ideas? Quote Link to comment Share on other sites More sharing options...
mhr1961 Posted December 31, 2018 Report Share Posted December 31, 2018 there are some other mustang forums that the same issue is noted. In most cases it was a loose wire at the sensor. It i is located on the driver side just behind the lower grill. Quote Link to comment Share on other sites More sharing options...

Cobra37 Posted January 5, 2019 Author Report Share Posted January 5, 2019 I'm still working on this thing, the reset buttons didn't work, so far. I will put it on the lift and clean the sensor plug. Then try it again. Boy howdy a lot of mustang owners are having this problem! Quote Link to comment Share on other sites More sharing options...
AKSHELBY Posted January 5, 2019 Report Share Posted January 5, 2019 General motors vehicles must be moving for the sensor to read correctly (that is the way it is programmed) maybe ford is the same .. just a shot in the dark.. Quote Link to comment Share on other sites More sharing options...
Cobra37 Posted January 6, 2019 Author Report Share Posted January 6, 2019 The instructions say to hold the on/off button on the SYNC radio while holding in the fast forward button, then drive the car above 20 MPH. We just tried it again, with the car rolling at 25+ MPH and still Don't Work. Next step is to clean the contacts on the plug for the sensor and try again.

Cobra37 Posted January 12, 2019 Author Report Share Posted January 12, 2019 Pulled the lower valance and found the sensor with a crack down the side and it was wrapped with electrical tape to hold it together. Ordered a new new one and was plugging it in when I noticed the plug was broken. Ordered a new plug and wire set from Rock Auto, going to install what I have. Wrapped the whole thing up with three layers of tape. Now I'm trying to find out where it's suppose to mount. Anyone have a schematic of the location of one of these?

Cobra37 Posted January 12, 2019 Author Report Share Posted January 12, 2019 Tie wrapped the taped up sensor to a tab jutting out from the grill. Drove the car, pressed the on/off button on the Sync and the fast forward at the same time. Still not working, still reads 50 degrees. Any ideas?

Cobra37 Posted January 21, 2019 Author Report Share Posted January 21, 2019 I replaced the pigtail and sensor. Temp still reads 50 degrees. Quote Link to comment Share on other sites More sharing options...
Cobra37 Posted April 27, 2019 Author Report Share Posted April 27, 2019 I've tried all the above suggestions, plus replaced the sensor. I've disconnected the battery, first for ten seconds, then for an hour. Was told I didn't remove power from the system for long enough. That's why I pulled the plug for an hour. Still does not work. Reads 50 all the time. Had a weird thing the other day, rainy cold day and temp went to -10, 30, 40 ad finally stuck on 50 again. My Ford dealer in this little farm town of Brenham, gives me a deer in the headlight look when I ask the service manager. Any one have any ideas what will work?

Cobra37 Posted May 23, 2019 Author Report Share Posted May 23, 2019 Finally got my ambient air temperature to work. Quite by accident. I hit a piece of trash on the highway late on night and put a gash in my front spoiler. I ordered a new one and as I removed the old one, I noticed one of the wires were crimped. Basically the wires were pinched and almost cut completely through. That's why the read out in the dash would give out crazy numbers when it was raining and the car was underway. I rerouted the repaired wires and and my temperature gauge works perfectly. I didn't have to reset anything. So if your temperature gauge doesn't work, check the wires.
