In a normaly aspirated gasoline engine manifold vacuum will be 18-20"hg at sea level. you will drop approx. 1"hg manifold vacuum for every 1000' in elevation.
The Abbreviation for Manifold Absolute pressure is MAP.
It uses a manifold absolute pressure sensor.It uses a manifold absolute pressure sensor.
diferential pressure sensor intake manifold plausibility

If there is oil coming from the exhaust manifold it generally indicates a bad valve stem seal or a worn out engine. (too much crankcase pressure)
The MAP (manifold absolute pressure) sensor monitors the intake manifold pressure changes and adjusts the fuel delivery based on its reading
It's the MAP sensor...Manifold Absolute Pressure.
The pressure regulator is located under the upper intake manifold. Find your fuel lines entering the manifold (right behind where the air enters the manifold)...the pressure regulator is on the bottom side of that cluster*%$. You will need to remove the upper manifold to reach it and change the regulator.
Manifold absolute pressure (MAP) can be calculated by measuring the pressure inside the intake manifold relative to a vacuum. It is typically expressed in inches of mercury (inHg) or kilopascals (kPa). The formula to calculate MAP is: MAP = Barometric Pressure - Vacuum Pressure + Atmospheric Pressure. In practice, automotive MAP sensors provide direct readings of this pressure, factoring in ambient atmospheric conditions.
The manifold differential pressure sensor is on the top of the intake manifold. http://www.dsmtuners.com/forums/newbie-forum/102193-i-need-help-mdp-sensor-install.html
