Hi, I have acura mdx 2006 model and from some days after running some miles it's started to show outside temprature approx -39 F, I am not getting where is the problem.

 

I had an issue like that on a late 1990s vintage Dodge minivan; the issue turned out to be the temperature sender which was behind the front bumper. A quick trip to NAPA for a new sender, unsnap and unplug the old one, plug in the new one, snap it in place, problem solved. I'd be surprised if your MDX is any more complicated than that.

 

Welcome to the forums.

This thread has been moved from the Second Generation RL (2005-2012) Forum to the car specific forum applicable to your vehicle.

 

It's worth a shot to just unplug the sensor & clean the plug/contact points
