WARNING: This page does not describe the selected car, but rather 31 other vehicles, including the 2006 Mercury Mountaineer, 2006 Mercury Monterey, 2006 Mercury Montego, 2006 Mercury Milan, and 2006 Mercury Mariner. However, it is still accessible from the selected car via links, so may be relevant.

The tube mounted DPFE sensor is identical in operation as the larger plastic DPFE sensors and uses a 1.0 volt offset. The HI and REF hose connections are marked on the side of the sensor.
