Recently my ambient air reading are incorrect. For sometime they have been slow to react, but recently they just are too slow to react or just flat out wrong. I have cleaned the sensor, but that did no good. My question is, if I replace the sensor behind the bumper, will that solve my problem, or is there something else at work that I'm not aware of?
I would appreciate any input from others. I would assume there are more than a few people with bad ambient air reading than just me! Thank you.

How do you know the readings are wrong?

 

Pretty obvious when my 3 thermometers--which all read within 1 degree of one another, show a difference compared to the cars reading. Also, just simply observing other readings from weather outlets, also show an error. Yes, I did initially calibrate the car thermometer, but it was only off 1 degree, and I can't complain about that. I guess the biggest issue is it simply takes too long to adjust to the current temp as it rises during the day. Again, I have no trouble replacing the sensor, so long as that will solve the problem, and the isn't something else lurking that would also cause a faulty reading. I do appreciate your reply, and hopefully you may have some knowledge about the ambient air temp function of the car.
