Do Alfa's use an atmospheric pressure sensor to compensate for driving at high altitudes?
If they do, where is it located?

They do, called the 'Altitude Compensating Device'. I believe it only really helps with idle at different altitudes.

Greg has a little information on it on his L-Jet write up;
