Outside temperature reading???
 

Hi all,

I have a 2012 Honda Civic LX and something happened today that is out of the ordinary.

Today, for the first time, an outside temperature reading showed up on the bottom left of my dash right beside the odometer reading. For one, it's stuck at -40 degrees. For two, it's not -40 outside. Finally, a temperature never even showed up here before. I didn't even know this feature existed in my model and was under the impression it didn't exist for the LX. I've had this car for 2 years now.

Does anybody have an idea of why this has suddenly happened and what it could be? Any help would be appreciated.

If you do not have the feature on your LX then you may need to reset the computer.

On the other hand, we have a 2007 EX with the OAT feature. My guess is that it uses a NTC (Negative Temperature Coef) Thermistor and the wiring to the device would be an open circuit for a default reading of -40C.

Thanks for h reply.

Is this something I can do or is this something the dealer should do?

The car should still be under warranty, so take it to the dealer and have them check it. It does sound like the computer (one of them anyway) is going a bit haywire, which could cause more major problems later.

isn't it 3 years or 60k?

I got just under 2 years but already 70k...

If this brand new car does this to me an they tell me the warranty is already up his will be the2nd and last civic i buy...

I bought a civic fo quality...if i wanted a piece of scrp metal i would hav bought a GM

What i the warranty on the computer?

Resetting computer is a very easy thing to do. Just disconnect the NEGATIVE battery cable and let it sit for a few hours, maybe overnight. There is a faster way but I do not want to take the risk that you may misunderstand my instructions.

I have a 2012 that had it go out like yours. It now doesn't read any exterior temperature and it is blank on my screen. Did you ever figure yours out?
