According to my Haynes repair manual, the Differential Pressure Feedback EGR sensor (DPFE) monitors upstream (before) and downstream (after) exhaust backpressure. By calculating the difference between the two pressures, the powertrain control module (PCM) determines exactly the EGR flow rate at all driving conditions.
Ford is the only American car company that uses a DPFE sensor. GM dpfe sensor are built into the EGR.
I'M NOT A MECHANIC but if I'm reading the engine wiring schematic correctly, the orange wires connected to the oxygen sensor(s) , connect to a gray/red wire which ties in the oxygen sensors to the DPFE sensor ( differential pressure feedback EGR sensor) which in turn is connected to the PCM (powertrain control module)
I have a 99 ranger 4x4 you might be surprised that you dont have a vss ! Instead look on your rear axel . its your abs sensor, or also called, rear speed sensor!
no
No. Their functional differences prevent installation. However, the 99 Ford Escort trans will fit in the back of the Ford Explorer to transport it.
i need to know wwhere the fuse is at for the power windows on a 99 ford explorer
yes
how do I get into my 99 explorer with it being locked and the latch being broke
No
I had this problem with a 99 Ranger. The DPFE is a rectangular unit about the size of a deck of cards, usually silver or black in color. It is located on top of the intake (mine was right in the center. It has a small vacuum hose on top and one on the bottom and a wire plug on the front. It is held on by 2 screws and takes only minutes to change. You clear the code by disconnecting the battery for a few minutes. Hope this helps.
