WebUnder normal conditions, actual atmospheric pressure or air pressure is usually around 14.7 PSI (29.9 inHg) at sea level. And when the engine is running, the plunging piston motion creates a vacuum. The intake manifold vacuum reduces the original barometric pressure by around 9.7 PSI (20 inHg), so the MAP sensor reading drops to about 5 PSI (10.1 inHg).
