You don't specify the engine size, but here goes....the idle air control is typically mounted to the side of the throttle body (where the throttle cables connect.) The EGR is typically at the left (driver's side) rear of the engine and the MAP sensor is typically mounted near the center rear of the upper intake manifold. It's a small black, rectangular box with a vacuum line and 3-wire connector going to it. Real question is why do you need to know? What kind of problem are you having? If your MIL light is on, and the code descriptions indicated that these systems were at fault, that doesn't mean these parts are bad. See the article I have at www.autoservicetech.com. Look in the related links for this answer. Hope this helps!
