The outside temp sensor is located at the bottom of the right side view door mirror! Don't ask me why they put it there.Usually the sensor is located in the front. When you are parked the sun heats up the mirror housing and it reads 10 to 15 degrees more!I had readings upto 104 when the outside temp was 90! I took it to the dealer and they ordered a new mirror (as usual you cant just swap the sensor! The entire mirror housing has to be swapped) but it didn't make any difference. Its a design flaw and you have to drive a few minutes until the mirror housing cools down!

Wingmirror temp sensors have been a thing for nigh-on 30 years now.
Not really a design flaw.


If your dealer swapped your wingmirror because of it getting hot under the sun I hope they didn't charge you for that.

Post #97 shows how to fix actual duff ones for a few cents.
But as posted before, first thing to do is clean the door loom connector.

This happens all the time but it can't really read asap when you first start the car for mine you need to wait for minutes or sometimes hours.

I have a 2015 jeep renegade. It sometimes won't start usually the first time, after that it mostly starts + the dash gives odd false readings (26 degreesin FL?). There are no fault codes retained. it has been checked 4 times last year. I can't be w/o it starting. Now they want to replace the mirror????

This is an old thread and this has been mentioned before but I am going to bring it up again because it is a serious safety issue. When the ambient air temp sensor under the passenger side mirror fails it will disable the drive modes and the auto start, it will has cause the HVAC to not work properly. I found this out other day when I was driving while it was -10 F outside and went to put my 2015 TH into snow mode and it did not work. I noticed the service engine light came on and the outside temp was reading -- I got the code checked and it was P0073 ambient temp sensor. Today the temperature was above freezing and the error code was gone and everything was working again. This also happens with several other parts on the car when it is extremely cold out. I do not have a garage so I am not going to try a take apart the mirror and atempt to pull out the sensor and replace it when it is 5 degrees out. So now I have to decide to live with it and hope it does not happen to often or have the dealer put in a new mirror with the same crappy parts and wait for it to happen again. This is a known issue and the dealer told me today they have replaced several mirrors because of it. I use the drive modes, I had to park in behind my house the the other day and to get there I had drive up a step driveway then through over a foot of fresh snow. I hope one day they come up with a real fix or a forced recall to fix it.

Great information, thanks for sharing!
