Outside temperature way off

[MacGreiner]

I have just noticed that my outside ambient temperature is show 20-30 F higher than it should be. Any ideas as the where the sensor is located and if anyone else has had this issue?

I have. Usually when I try to get a temperature after the car has been driving a long way or just after supercharging. Both of these I attribute to warmth coming off the battery. It corrects itself over time or after a few miles on the road.

Also, if it is parked in the sun, it will tend to show a temperature higher than the air temperature because the pavement heats up and in turn warms the sensor.

This is when driving along at both local and highway speed. Doesn't seem to correct over time. Smells like something that needs a tech to look at by the looks.

Yeah, mine has been all over the board.

Outside temp sensor (black and white clip) is located in the front bumper gap shown here. We have seen this issue occasionally. It seems that hot air can get trapped and it will read incorrectly. Removing the bumper and re-positioning the sensor slightly seems to work.
