EGR or DPFE is located on right side of intake manifold. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

Egr vavle is mounted on the intake manifold, if it is going bad you will probably have trouble codes, and you will have rough idle, rough acceleration, bad performance.

I have gotten a P401 code, and it relates to a problem with the EGR valve. My questions:

1. What does the EGR system do?
2. What harm am I doing to my engine until I get this fixed?
3. How difficult is it to replace/
4. Where is it located?

EGR= Exhaust gas recirculation system, recovers unburned vapors for re-burning in the engine. Will not pass your next state inspection and could lead to more trouble if not fixed.
Here's what to do:
Pull the egr off, clean the port under it all the way to the throttle plate, I use a length of steel coathanger. Put it all back together, reset the codes, if light comes on again, replace the EGR position sensor, thats the one the two small hoses from the exhaust plug into! First make sure the EGR itself holds vacuum! If the valve dont move, it will also set P0401!

We don't have state inspections here, so that is not an issue. Where would I find the EGR valve on my 98 ford taurus stationwagon? If I don't fix it, what long term harm might happen?

What can happen is engine hesitation, also the carbon will start to fill in the intake manifold, then you need to remove that and clean out the carbon, Also if too much unburned gas collects in the catalytic converters, they will be damaged. this is a 10 minute fix, Go to the local parts supply house, buy a new EGR gasket before you do it, if the EGR opens and closes and the diaphram holds air, do what I said...EGR is on top of the motor toward the passenger side, look at the back exhaust manifold, you will see a flex tube thats about an inch in diameter, loosen the large nut on the EGR then the 100 mm bolts, pull EGR off, clean both the EGR pintle, and the port, and re assemble. DONE!

Thanks for the info. Let me make sure I have it right.

Step 1, remove EGR valve
Step 2, use a steel coat hanger to clean out tube? Do I just insert it all the way down? How or what do I use to clean it? Am I just trying to unblock stuff?
Step 3, reinstall EGR valve reset code and see what happens/
Step 4, if still get code replace EGR valve and reset?

Under the EGR is a port that runs right down to the throttle plate, ream it out with the coat hangar, then spray throttle body cleaner thru it, clean throttle plate, and EGR. Make sure EGR holds vacuum! Then reassemble, clear the code, if the code resets, and you are sure the port is clear under the EGR, Replace the EGR position sensor, not the EGR!

I went to get my inspection sticker and was told there was a problem with my EGR valve. He said it may be a vacum problem. What other problems could there be with the EGR valve (i was reading over some of the messages youd previously recievd and saw where one man thought the valve may be dirty)? Secondly, where exactly is my EGR valve located and how would I go about changing it out myself? Should it be left up to a professional?

What code did you have? 401? I find in most all situations that the problem is not the valve at all, it is the sensor that detects exhaust pressure that fails. This is call the dpfe sensor and is very simple to install, unscrew 2 eight mm bolts unhook 2 vacuum lines then install new part. Hope this helps

Okay what or how should I clean the EGR valve? Is there a certain type of cleaner, do I need to soak it in something? As for the position sensor, where is it located? Also how do I test the egr to see if it holds a vacum?

It was 401. So its probably the sensor? Great i'll look into changing that out. Where is it located? Near the egr valve or in a different area alltogether?

You seem to NOT be reading my answer thoroughly. SEE IF TH EGR holds vacuum, clean only the blacked PINTLE with soapy water, or TBI spray cleaner. Do this and see what happens. The sensor occasionally MELTS with the heat. Follow the two small tubes from that flex tube to the sensor, BE VERY gentle removing the rubber tubes, they break easily.

I was reading your mind. Purchase the new sensor first it cost about 30 -40 bucks, then look at engine and try to match it up, this should be fairly easy. Look for 2 gray rubber hoses they will connect to it, there are only 2 gray hoses under the hood so this makes it even easier and you will be surprised how easy it is to replace.

There seems to be a slight problem with my vacuum hose leading to the egr valve? I'm not fluent in mechanical terminology, but every time I start the vehicle, it sounds weak, and the hose keeps popping off. I had a similar problem a few weeks ago to where my car would actually not start, however, I just popped the hose back on and it worked fine. Im located in arizona, and I believe that the weather changes might be screwing with the shape of the hose. Would this affect the way my car would start or even run? Is it a hose problem or an egr problem? I appreciate your help.

Hi:
the hose is providing vacuum to the EGR. When the engine is running, remove the hose and see if there is pressure coming from the EGR. There shouldn't be. If there is, replace it. Also, to answer your question about the hose, yes it can cause a poor idle. Take the hose off and take it to the local parts store and get a new one and replace it.

Let me know what you find.

I am having a problem with my car dying when I am stopped for longer than a 2 minutes. It is though my car is not getting enough gas when I am idle. My engine will shutter then the car will die. I recently had my EGR valve and coil on cylinder one replaced. My check engine light is on. I had it read and it says I have insuffencient EGR flow. Today my car when in neutral started reving up to 2 rpms then just dropped below 1 rpm and then died. What could be the problem.

Thanks.

Let's start the exact code number, rather than description for the check engine light. All of them if you have more than one. Also please post the first 8 digits of your VIN. I need to know the actual engine you have to provide accurate info.

I get three codes:

PO401 -- EGR Value has insufficient flow

PO171 -- System lean

PO174 -- System 2 lean

The first 8 numbers for my vin is IFAFP56S
