The greatest thing in the world to happen before a 6 hour trip happened as I pulled out of the school parking lot... SES light pops on. Took it to autozone today and the code came back EGR flow... soooooo, the guy said just to clean it and it'll probably be alright, but I forgot what he said to clean it with. Any suggestions? Thanks

Use brakeCleen. You can get it anywhere. Most mechanics use this on everything, because it's not abrassive enough to ruin ellectrical and emmission parts, but effective enough to clean your egr valve.

Well I called Bob from Wal-Mart to find out if a product was okay to use, because they didn't have Brakecleen... so here's what he said: The problem probably not the EGR valve, and if it is, its stuck closed which isn't a big problem, it just inceases emissions a bit. The car isn't running rough or anything, so he thought it was probably another sensor in the system. perhaps the PCM?

Was it a P0401 code perhaps???
If so you need to replace your DPFE sensor!! Test the EGR valve w/a vacuum pump. If the EGR valve is bad, it's probably carboned up. Cleaning it may work but usually we(Ford Techs.) just replace them. They're not very pricey, & IF you use a FORD part, you'll most likely never have the problem again. DO NOT use Brake Clean unless you have the EGR valve OFF the engine!!! Spraying Brake clean into an engine makes them run VERY badly... possibly not star well, & may hurt the O2 sensors. True, this may not be a long term concern, but it'll be annoying for awhile. We usually use Carb/Throttle cleaner for such things.

My moneys on the DPFE sensor. I had the same code, replaced the sensor, and never had the code since.
Good Luck!

remove the tube that connect to the top of the egr valve.. with the engine idling.. suck on it... if the engine flutters.. as if its about to die.. and then idles normal afte ru stop sucking ...then egr is opening & closing ok...

then jus tchange the DPFE.. abt 60 bucks at autozone..
FYI I had been driving my 96 GL for abt a yr with the P0401.... before I changed the dpfe.. no issues...

If it is the DPFE sensor, no matter what people say, just change it. If it is an emission problem, you can cause other problems by neglecting it. Like a plugged up cat, or other problems.

Yea actually mine check engine light came on too and i had the same deal with the EGR valve. You will have to replace the sensor, as i am going to do also. I took my car to autozone and he told me to clean it out, like the manual for the code says, so i did, and its still on! I think its pretty common for fords for the sensor to go bad.

The DPFE is a real common sensor to go, on the Ford engines.....

So that was you.... With a staticy cell connection, which was on my end, I could have sworn you said it's Adam. That's why I asked if the car was a 90 or 91. Something about driving, eating a donut and sipping an iced coffee, while talking on the phone in rush hour traffic confused me. That's about a dozen more things than I can handle. :p

Anywho, how'd you make out?

The cats will not get plugged up from this. Actually, the EGR not opening causes less crap to enter the intake stream, which results in less crap in your intake and ultimately your engine. If it plugged up your cats, everyone with a removed EGR would have plugged cats.

I wondered why you asked me if it was a 90 or 91... you guys are going to laugh at me, but my mom won't let me fix it myself. *waits for the jokes and laughing to stop* She said if I clean the EGR and replace the DPFE sensor by myself I'm not allowed to go to Michigan...so that was the end that...lol (yes i did tell her i could save tons of money, and also told her if it goes to the dealer she's paying for it.) I'll let ya know what they do

What does the DPFE sensor do exactly, and why do I even need it?

$85 for the DPFE sensor and $101 for labor. Ug... at least my parents paid for it - that was part of the deal when my mom said she was calling the dealership... if it goes to the garage I'm not paying. On the upside, I got to look at some new Taurii and Stangs... found a couple I wouldn't mind having.
Good Lord. It is a simple matter of unscrewing two screws. It takes less than a minute. :uhoh2: I mean, seriously, its RIGHT THERE on top of the manifold. $101 of your moms money was just wasted.

EGR Back Pressure Sensor

Is this the same as a DPFE Sensor?

First Post BTW, Great Site!

:welcome:

Link's broke due to the way Autozone's catalog is set up, but that's it. You may want to try rockauto.com, they usually have good prices.

Welcome to the club -
and that's the DPFE. Autozone, $72, Rock Auto, $25 + S&H (http://www.rockauto.com ) - look in the pinned section of this forum for people posting the 5% discount code you can use to save even more.

Dave

EDIT: whoops, while I was looking it up on Rock, Michael was posting exactly the same info. Oh, well.
