2012 nissan sentra outside temperature display not working correctly. Displaying 10 degrees colder than actual outside temp.

Please to use a thermometer in the radiator after the engine has run about 10 minutes to test the actual temperature of the coolant.
You may also choose to put a piece of flat cardboard over half of the front of the radiator to see if that makes it heat up more.
The temperature should be about 180 degrees, unless you have added a 160 degree thermostat to the engine, in the which case the radiator temperature should be nearly 160 degrees.
If the radiator shows the proper temperature, perhaps the temperature gauge on the dashboard or the engine block sending unit is defective.
God bless your efforts.

Pull battery teriminals off and cleaned real good

there is a air temp sensor that controls the ac as well

im not sure if this can be abjusted or not but i can tell you why its saying its hotter that in realy is.. its because its telling you the temp under the hood. its recording the heat from the engen.....so this adds a few degrees to the actual outside air temp.... i hope this helps you

I have a 2000 pontiac grand prix with a digital climate control system. The heat quit working, it doesn't blow out any heat. Now that it is warm outside the air stopped blowing out any air. The digital temperature on the climate control is not correct. When it states that it is below 30 degrees on the ext and it is warm outside the air wont be cold. Once it starts going above 30 degrees the air gets colder. Today the blower stop working all together. Was told it maybe the climate control unit was bad. You can hear the door opening/shutting when you switch the temp from cold to hot. But there was no heat blowing out whatsoever in the winter time. Could you please give me your opinion on whether or not it is the climate control unit or something else?

the outside temperature sensor on vehicles takes the temperature of the air about 2-3 inches off the ground, that close to the ground it might be a couple degrees colder than the temperature on the thermometer you have mounted in the window of your house.

you need to replace the ambient temperature sensor or do the math

Had the same problem, replaced the ambient air temp sensor in front of the radiator. Cost is like 10-15 bucks. Don't worry if temp doesn't change right away. Took me about 5 miles and then it worked great.

Probably a burnt light bulb

There is a technical service bulletin stating that if your car is equipped with a 2.5 liter engine that the ecm may need reprogramming.Contact your local nissan dealer with your vin # and they should be able to help u further.
