Default Outside air temp

Here's a silly and seemingly pointless question. Where is the sensor for the outside air temp gauge on an '04 STi? If I lean way over to one side or the other, I can catch a glimpse of the readout in the instrument cluster (normally hidden behind the dumb stock boost gauge).

I'm actually wondering because I would like to know whether or not it's likely to be influenced by underhood temperatures. Doing some datalogging, and would like to use it as a reference.

Searching didn't produce anything. Thanks.

in front of radiator. engine temps are probably not going to affect it too much.

Most likely its in one of the front fenders or the front bumper. I know the one on my RS is about dead on accurate.

Its pretty cool, I've driven on city street and then got on the highway and immediately saw a 2-5 degree jump in temperature. And the same drop as i exit. You'd be amazed at how much warmer the air over the highway is compared to the city.

As far as i know it is not affected by under hood temps and you can use it as a reference point.

HD is right.
According to the manual, the display electronics ignore readings while the car is moving slower than 10mph so engine heat doesn't affect the displayed number too much.

That's where they are on most vehicles.

I just discovered this evening that it's below the level of the TXS FMIC. My UTEC read, IA temps have been consistantly low compared to the dash for a while. I moved it up to another threaded hole in the grill. I'll see tomorrow if there is more consistancy between the dash and the UTEC.
