Sensor-Boost Pressure: Description
WARNING: This page is about a different car, the 2006 Dodge Magnum, 2006 Dodge Charger, and 2006 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.
The boost pressure sensor is mounted in the charge air cross over air tube, just past the air control valve. The sensor allows the ECM to monitor air pressure down stream of the turbocharger. See Fig 1.
