#188 of 193 2010 Mazda3 Ambient Air Sensor
Jul 14, 2009 (3:38 pm)
My dealer told me an "alert" was sent to the dealerships regarding customers complaining that the ambient air sensor (AAS) in 2010 mazda3. It seems that many customers have been complaining that the temp reading stays the same for several days regardless of the outside temp. I've found that the reading only INCREASES (this is not the case when decreasing) when you travel for 20 mph for 90 seconds and then the temp only increases 1 degree per 90 sec.
This is a problem for me because I live in Miami, FL....there are very few days that I meet the requirment to change my temp!
As of today I discovered that the temp changes if the car is turned off, ie: I parked my car and prior to turning it off the temp displayed is 94, 3 hours later start my car and the temp displayed is 104. After driving a few hundred yards the temp dropped a couple of degrees and with in several minutes (please keep in mind that I an not driving over 20mph for 90 seconds...the requirement to INCREASE the temp) the temp is back down to 94. So the AAS works fine if the temp needs to decrease, yet to increase the temp you have to meet the above mentioned requirements
Is any one having an issue with this? If you do contact mazda customer care!!!!

Wow.. not sure how you figured allt he 20mph for 90 second thing... but yes.... I have a problem my my Ambient Temp Gauge too.
If my car sits in the sun for a long time...it will read 70+ degrees... (when it's 95-100 degrees outside). Then it takes about 20minutes or so for it to actually read correctly. It's kind of a pain.. but not a real big issue imo.

I am having a problem with my ambient outside temperature reading. Seems like
it takes forever to respond to a temp change. the gauge is in the dashboard, not
the mirror. Some times after a ten minute drive, the temperature does not move

Oh, I didn't figure it out myself, Mazda told me. This was how it was designed to work. If you have the time contact Mazda 800-222-5500. You will need your VIN # and complain. If enough people complain then they will consider a voluntary recall to install a newly designed sensor.

The AC in my car has been working ok... Its a 2005 with no auto-climate. It is defintley no the best and I live in the Fort Worth... so it is very hot. And my seats are black so they heat up easily.

I purchased the 2010 Mazda 3 about 6 months ago. I too have been experienced the inaccuracies of the climate control. I've had the temperature sensor changed out once and the new one works worse than the first one. I live in CA and for the past week we have been experiencing temps. of over 100 degrees; the temperature on my display has never read over 70 degrees. As stated above, the temp. will decrease if needed, but will not climb as quickly as it drops. I've called the dealership and complained, their only recommendation is to drop my car off for several days so they can test it themselves, but refuse to provide me with alternate transportation. The dealerships have also been given specific instructions from Mazda to NOT replace the temp. sensor, as this is the way it is suppose to work. I find it hard to believe that you need to drive your car for over an hour in order to get a true temperature reading. I will call Mazda AGAIN and complain, but don't think anything will be resolved.
