Its defo taken from the MAF.
When your driving especially if your going fast / have a good cold air feed it will read lower than the ambient temp because of what is effectively the wind chill factor.
The temp will rise when you stop because of heat soak under the bonnet.
Oh and If you have a good FMIC and drive fast I reckon you could get inlet temps down well below freezing on a 1-3*C day like weve had recently. My Inlet manifold is genuinely substantially colder than the ambient air after a long motorway drive. Really need to get myself an inlet temp sensor.
