There's no mention of a MAP sensor in the factory service manual, but there is a MAF. What would be the purpose of a MAP sensor if the vehicle has a MAF? The vacuum in the manifold should be directly proportional to the air entering the throttle body. Back when I was still working on cars while in high school cars had one or the other, but I don't recall any instances where they had both. Alldata suggests a few Ford products (2.3L Ranger, 2.3L Focus PZEV, and 4.6L SC Mustang) use both Thermal MAP (TMAP) and MAF sensors, but that appears to be a relatively recent (relative to most of my experience) and not widespread incorporation.
