Crossfire SRT-6 V6-3.2L SC VIN N (2005)
Manifold Pressure/Vacuum Sensor: Description and Operation
The Manifold Absolute Pressure (MAP) Sensor is mounted in the Charge Air Cooler below the Throttle Body. The sensor allows the PCM to monitor air
pressure within the intake manifold. The sensor is used to measure both vacuum and positive pressure (supercharger).
On the Supercharged 3.2L engine, the MAP serves as a PCM input, using a silicon based sensing unit, to provide data on the manifold vacuum/pressure
that draws/pushes the air/fuel mixture into the combustion chambers. The PCM use the map data combined with the intake air temperature to determine
the volume of air entering the engine.
