Where is the EGR valve located

When I opened the hood to look at my engine I found that a vaccum hose had come loose. I fixed the hose and ran the car with no problems. Then I turned on the air conditioner and could hear a sucking sound from the intake manifold. The rpms started to fluctuate, the car shuttered and died. I drove the car without the air conditioner and it drove fine. Cleared out all codes (from previous response) and the check engine light hasn't come back on.

If I am idle for any length of time with the air conditioner running the car will die. If I turn off the air conditioner the rpms stabilize and the car runs fine.

What could cause this?

What is the easiest way to replace the EGR valve, and do I need to apply any sort of silicon to the gasket? Thanks.

Yes I got a check engine light that said the EGR was stopped up. I figured because of the age and mileage of the car I should go ahead and replace it. Thanks for your reply.

I have a 99 Taurus 3.0 DOHC. The check engine light came on, so I had it check at Auto Zone. The said it was the DPFE sensor. I change the sensor but the light never went out. I took it to Ford and they said the DPFE sensor is bad. I told them I change it already and they said the computer says its bad. They reset the computer and the light went out for a short time but came back on. Could it be possible that the new sensor I bought is bad or is there something else that could be telling me that the DPFE sensor is bad?

Hi, I have a 97 Taurus LX, 3.0 24V Duratec Engine.

The SES light was on, I had it tested and they said the EGR flow was both insufficient and excessive.

Today I cleaned the EGR valve, reset the PCM, and the SES light was off for a little while, it just now came back on.

So, do I need to get a new EGR valve or a new DPFE sensor, since these vehicles are notorious for those sensors failing.

One reason why I don't think it's the sensor is because the SES light was actually off for a while. If it was a faulty sensor, wouldn't the light have always been lit?

Thanks!

I have a 2001 ford taurus with 122000 miles with a 3.0 v6 engine, my dpfe senor blew, I was told that my coverters and o2 sensors may need changing, but I was aso advice to change the dpfe sensor, I did and the new sensor blew also,
can my o2 sensors and cat conveters cause this problem?
Also is I t possible that my 02 sensors can be bad nad not my cat conveters?

WOW!
I'm assuming that you're doing this because your check engine light codes are indicating that you may have a problem with the dpfe sensor, o2 sensors & the catalytic convertor.
Sir, if you could reply with a bit more details, maybe I can help. The faults codes could be a good start. Just so you know, even if the 2 hoses that connect to the dpfe sensor are bad, the computer will say that the dpfe itself is bad. So insted of changing stuff that you don't need. You might want to consider have a diagnosis performed on your vehicle at a local repair shop! It would be well worth your money!
Hope this helps. Good Luck!

The hoses going from the egr valve to the sensor blew off and the sensor burnt up. I replaced the sensor and reattached the hoses - one week later the same thing happened again - any idea why?

The same thing as a DPFE sensor? I would like to know because it seems as if I need DPFE sensor to fix the fault code (P1401) on my car (2001 Ford Taurus). At least that's what everybody is telling me. So I'd like to know if this is the same part before I buy it. Thanks in advance.

Peace.

An EGR valve pressure feedback sensor? I found that at the NAPA store back home for like $31, so, that ain't nothin'. It also fits the description that TaurusWheel gave me for a DPFE sensor just above here. Yay or nay?

Peace.

Hi
I have a 1995 Ford Taurus 3.0 V6, around 81000 miles.
I found that the EGR pressure sensor has been damaged by heat that is coming from the pressure tube connected to the pipe that runs from exhaust manifold to the EGR valve. My question is, Because of the very hot gases coming out of the tube, what keeps the rubber tube and the EGR pressure sensor from melting? I hope this question makes sense, because I don’t understand how I can keep the sensor from getting damaged.
Thanks

Thanks for your reply, TaurusWheel
Only one has been damaged that I know of. Here is a little history about this car. It belongs to my stepdaughter; she received it from her aunt who did not take the best care of it.

Because of the heat coming out of the metal tube into the rubber hose and eventually to the sensor port has caused the damage. When I found the damage, the rubber hose was burnt from the stream of hot gases coming out of the metal tube and before the rubber hose failed it cause melting type of damage around the sensor port from the hot gas. I know this seams like a dumb question, however, hot exhaust gases are suppose to come out of this tube right? The pressure sensor is there to monitor the pressure in the pipe running between the exhaust manifold to the EGR valve, right? Could the EGR valve not opening or working correcting be causing the hot exhaust gas to build up and leading to the EGR pressure sensor damage?
I hope this makes sense, a lot of words to describe this problem.
Thanks for the help.
