Re: Outside Temperature Sensor Problem

Sigh. It seems that my 12 Overland suffers (or has suffered) from every known problem, including this one. If theres a TSB, my Jeep most likely has the problem.
Temp today was showing 81, when it was barely 65 outside. Takes forever to adjust, you have to drive fast and for a long distance before it seems to register the correct temp. I've been noticing that the temp is way off and adjusting slower over the past few weeks.

This is hardly new technology, and the first vehicle I've ever owned to have this sensor problem.

Re: Outside Temperature Sensor Problem

2014 model year vehicles

"Ambient Air Temperature Slow To Update, Will Not Update, Or Inaccurate"

Slower ambient temperature updates, primarily noticed during lower speed stop and go driving or after the vehicle was driven and parked, engine off, for less than 4 hours and 15 minutes.

If the vehicle is started, within the off time period, the last known ambient temperature display strategy displays the last temperature at vehicle ignition off (or possibly a colder temperature than period up to 4 hours and 14 minutes later) and displays it.

Updated temperature readings will not update until the programmed speed and time criteria are met, this during low speed stop and go conditions can take in excess of 8 minutes to update. This ambient temperature display strategy is unique for the 2014 MY vehicles.

Therefore, if there are no diagnostic fault codes “Active” or “Stored” related to the ambient air temperature sensor no further updates or repairs will change the operation.

The ambient temperature display strategy will be updated with revised software update for 2014 MY vehicles and should be available fourth quarter of 2013.

Re: Outside Temperature Sensor Problem

Thanks for the update Milous and glad they are fixing this. It's a big problem for me now that summer is here and it's heating up quick. I drove into work yesterday with the temp. at 75F, then when I went out to lunch about 5 hours later it still displayed 75. The true reading should have been near 100, but it never updated since I didn't hit the driving requirements.

Thanks for the update. It doesn't seem like this strategy was well thought out.

Re: Outside Temperature Sensor Problem

On my 2012, it is pretty darn close. I compared to my other vehicles temp display and they match by a degree or less (sometimes, they are the same).

My 2012 is 5 degrees hotter, not a big deal but my 5 year old civic has a more accurate temp reading.

Re: Outside Temperature Sensor Problem

My overland exhibits this issue too. It's annoying because I'd like for the vented seats to kick on whe it's been roasting in the car but they don't. I love black on black, but in NC in the summer, it's a problem.

Thanks for the update. Seems odd though. We are expected up to 119 today and was curious the temp now.

You should be able to set it so the drivers vented seat comes on automatically when it's 80*+. It will only come on in the low setting though.
I have mine set this way but low is not effective so have to bump it to high anyway! Another goofy set up by Chrysler!

Re: Outside Temperature Sensor Problem

Could the low vented seat setting, along with low a/c fan setting be an attempt to keep power draw low while the engine is idling?

That certainly could be the case but I would think that some simple programming should allow for both fans to operate for a period of time on high even at idle. If at idle for say 5 or 10 min then auto reduce the fan settings to low. These things are supposed to be so smart but I wonder what the programmers are thinking some times? lol

Re: Outside Temperature Sensor Problem

The temp outside reading is useless. I usually park my car in a garage which is heated/cooled. The moment I pull out of my garage the temp reads 75F.

I went to store, came back (about let's say 10 minute drive) the temp still shows 75 even though it was 90+ outside.

On my 01 Pathfinder haven't had this type of an issue. The reading was spot on most of the time and was much faster to update. Seems like a step backwards for Jeep.
