Fuel Pressure Sensor
WARNING: This page is about a different car, the 2007 Chrysler PT Cruiser. However, it is still accessible from the selected car via links, so may be relevant.
The fuel pressure sensor monitors and passes on the current rail pressure to the control module. See Fig 1. The non-constant system pressure influences the position of the sensor diaphragm which alters the sensors electrical resistance.
