Here's what I know about temperature guages:

First of all, I have an outdoor thermometer fixed to my southeast window here in Topanga. When the sun hits it directly around 10am and it reads 120F, I know it's because of the direct sun. By noon, in the shade, I know it's reading normal. It was maybe 96 up here today. Same thing applies to just about every outdoor temp guage -- direct sunlight, or radiating heat from a nearby parking lot or roadway (or AC units) will upwardly misrepresent the actual ambient temperature. And I'm guessing the same applies to bike temp guages. Maybe not over-reading by 10 or more degress, but it has to be affected. What do the bike guage manuals say about direct sunlight and misreadings?
