Quote from HDDP >>>"Good questions... First let me start by saying that only the NA Crossfire has just the MAF sensor, the SRT has both MAF & MAP."

The 2004 Service Manual begs to differ... see pages 14-42 to 14-43 Also, it is actually on the my engine. Since this is an Sequential Multiport system it uses both the MAP and the MAF.


MAP SENSOR
DESCRIPTION
The Manifold Absolute Pressure (MAP) sensor, is mounted to
the front of the engine on the right side next to the air pump.
OPERATION
The MAP sensor monitors the pressure in the intake manifold. The pressure in the manifold moves a diaphragm
connected to piezo resistors which alter their resistance values. The output voltage of the resistors serves as information
to the PCM about the pressure in the intake manifold.
REMOVAL
1. Disconnect the negative battery cable.
2. Remove the air cleaner housing. Refer to Page 9-608.
3. Disconnect the Manifold Absolute Pressure (MAP) harness
connector.
4. Remove the retaining bolt (1).
5. Remove the (MAP) sensor.
