How to test - replace the EGR valve - DPFE Sensors on Windstar?

Answer 1

This is a pretty straight forward replacement - only 2 mounting bolts, a vacuum hose and one other pipe that'll come off with an adjustable wrench.

NOTE: this notice is from the Autozone.com site regarding the EGR valve:

* **Caution!!** Before replacing the EGR Valve, inspect the DPFE/EGR Valve Pressure Feedback Sensor and hoses for proper operation. It is common for a DPFE sensor to set a trouble code See "Related Links" below for the DPFE sensor section of Autozone's online repair guide. It is located at the back of the engine on the top between the engine block and the front windshield. It should be black or chrome colored and kind of looks like a disk, with a small vacuum hose coming out the top of it. Just replaced mine in my Taurus today. Amanda nothing tricky, just be sure to clean the gasket surfaces...also You should be able to find a shop manual at your local library with the right info...make copies as they are usually only in the REFERENCE section....good luck:) its located next to the air inlet boot this is the boot that comes from the air cleaner housing the valve should be round black and has a vacuum line going to it But, if you are replacing it because there is a code for it you need to make sure that the valve is cause of it most fords had a problem with a sensor called a DPFE sensor which stands for differential pressure feedback exhaust sensor the problem is they would get moisture from the exhaust causing them to short out on most 99 models the egr valve is connected to the intake manifold.If you look at the top of the engine,while in front of the vehicle with the hood up,look just to the right at the right side of the valve cover tou will see a round shaped two inch thick just underneath clean air intake plenum tube also knownasthe air intake plenumtube hooks to the fender in most vans however this can be a tricky part to replace I sugest you get a chilton or haynes manual to help you out. Just look it up in the index or glossary and read the passage severaltimes before starting the work also pay close atention to how it comes of and apart because installation of the new valve will be reverse the procedure GOOD LUCK and GOD SPEED ---- It is attached to the throttle body. The throttle body is attached to the intake. Look for the large aluminum piece that will say Ford, this is the intake. Look for the large tube going in to it, probably from the left if you are facing the windshield. where the large tube goes into the intake, it will first go into another piece of metal with wires etc going into it, this is the throttle body, the egr is on the throttle body. ---- I can answer my own question!! With help from a mechanic friend of mine...back ,top, center of engine, you will find the pod...Good luck to anyone trying to reach it, looks unreachable to me, barely viewable... ---- EGR Valve Inspect | Test | Replace There are many variations from one vehicle application to the next in emission control systems and calibration. Therefore, it is extremely important that you get the correct replacement exhaust gas recirculation (EGR) valve for the application. Two EGR valves may look identical, but be calibrated differently in terms of flow and the amount of vacuum and/or back-pressure it takes to open the valve. Therefore, you may have to refer to the vehicle's VIN number as well as year, make, model and engine size when ordering a replacement EGR valve. If may also be necessary to refer to the OEM part number on the old EGR valve (if possible) when ordering a replacement. If so, don't throw the old EGR valve away until you have installed the new one and made sure it's working correctly. Many aftermarket EGR valves are "consolidated," so fewer part numbers are necessary to cover a wider range of vehicle applications. Some of these valves use interchangeable restricters to alter their flow characteristics. Follow the suppliers instructions as to which restricter to use for the correct calibration. ---- This part cannot be cleaned....you can check it for replacement by allowing the engine to warm up and you should be able to move the diaphragm in with your finger (from behind)the egr...the factory default is sealed in the front

See "Related Questions" below for a similar discussion over in Taurus group - it all applies quite well to the Windstar ---- Real easy to spot-- Look to the LH side of the engine-- towards front-- It's a little black plastic box 1 inch by 1 1/2 inches square, 2 hoses connect to the bottom of it, and an electrical connector off tot the side. To disconnect the connector you have to squeeze a tab first before pulling, remember!

your check engine light will come and give a code for emmission can't remember the code. Put I had the same problem on my 2001 Ford Ranger.
