ACDelco Manifold Absolute Pressure MAP Sensor 213331 EFI Connection, LLC


Under 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.

MAP sensor (MANIFOLD ABSOLUTE PRESSURE) measures total pressure in engine's intake manifold


MAP Sensor Overview. A MAP (Manifold Absolute Pressure) sensor is an electronic device that measures the pressure in the intake manifold of an internal combustion engine. The MAP sensor provides information to the engine control module (ECM) about the engine load, which is used to determine the air-fuel ratio and ignition timing.

Manifold Absolute Pressure Sensor Wells Vehicle Electronics


The Manifold Absolute Pressure sensor or MAP sensor is a sensor that is attached to the intake manifold on a car's engine. The MAP sensor responds to changes in the intake manifold pressure (vacuum) and provides a reading of "engine load". How it works is 5 volts DC is supplied to the sensor from the PCM (powertrain control module).

ACDelco Manifold Absolute Pressure MAP Sensor for 6.6l Duramax LB7 LLY LBZ LMM 20012010


The MAP sensor measures the absolute pressure inside the intake manifold of the engine. At sea level, atmospheric pressure is about 14.7 psi (pounds per square inch). When the engine is off, the absolute pressure inside the intake equals atmospheric pressure, so the MAP will indicate about 14.7 psi. At a perfect vacuum, the MAP sensor will read.
