Manifold Pressure/Vacuum Sensor: Description and Operation
Manifold Absolute Pressure Sensor
The Manifold Absolute Pressure (MAP) sensor is used on some applications. The MAP sensor measures the pressure in the intake manifold and
provides this information as a variable frequency signal to the Powertrain Control Module (PCM). With the Ignition Switch in the Key ON/Engine OFF
position, the MAP sensor will indicate the barometric pressure in the intake manifold. The MAP sensor is used to indicate boost pressure on the diesel
engine.
