You are "old school" much like Glenn and that is rare now days. Good, smart, and honest mechanics that know what they are doing are a rare find. When you do find one you keep using them and recommend them to your friends.
WRONG!! As I said there are reflashes out on particular model Minivans tha require a flash of the PCM to install software that will update the engine controller for an intermittent fault for turning the Check engine lite on and setting a code for the EGR . Once again ...WORNG The newer model vehicles do NOT use a vacuum controlled EGR. it is all electronic. If you knew what you were talking about you would Know that a P0404 fault code is An EGR postion sensor fault there fore this valve is strickly electronic and DOES NOT use vacuum to operate the EGR valve. Try again
Glenn
If one were to assume that vacuum operated EGR valves and EGR position sensors must be mutually exclusive in any possible EGR system then one's assumption would also be WORNG.

Like I said - no model info so we are all guessing. Last Chrysler I worked on was a '98. PO401 code - insufficient EGR flow.(had to go check) PO404 means the sensor thinks the pintle(or whatever) is in the wrong position for the requested flow, while PO401 means the A/F ratio does not change in proper relation to the requested flow. (Insufficient EGR flow)
I know what the codes means and how to diagnois them, You were saying that "The least they could have done was check for a bad vacuum hose" I was just point out there this vehicle has no vacumm hose and has to be diagnoised with a scan tool. Ap0401 and a P0404 are 2 totally different faults
Exactly what vehicle are we talking about? Don't remember it being stated.
And SOME vehicles use elecrit controls to vacuum operators, with electrical feedback. Same codes can STILL be aused by bad vacuum components. Mabee not on a Dodge?
Quick, name a Dodge vehicle with a vacuum operated EGR system that uses a position sensor.
And what the hell does 'WORNG' mean?
OK Maxpower,
I have 2 minivans, a 94 and 95 T&C with the 3.8L BOTH vans do this - set the EGR code in the CEL, intermittently. I've swapped valves, replaced them, taken the old ones apart. No problems, no cracked diaphram, selonoids work. EGR system passes all the diagnostics in the FSM. Both vans pass NoX emissions with flying colors. This problem has been happening for years on both of these vans.
This is the FIRST time I've read in this forum any statement from anyone claiming to be a dealership mechanic that this is a known problem with a firmware update for the engine computer to fix it on certain vans.
So, are mine part of this known problem? If so, what is the TSB #?
Ted
Hi Ted
Yes and here is the TSB# 18-01-97 (keep in mind this is a Canadian TSB # not sure if it is the # for the states) Claude
What code? EGR Solenoid Circuit or EGR System failure?
You mention nothing about replacing the part with a new part? The tiny male pins in the transducer solenoid are known to get water in them and corrode or even break off and setting the Solenoid fault
I never said it was a know problem. The OP was crying on here about his deal with the dealer and I said Since he wont give out year/make/model he wont get help. I said there there was a reflash out on a particular year van. There is no reflash out on yours.
Max
There is a flash update for said vehcile TSB#18-01-97 (keep in mind this is a Canadian TSB # not sure if it is the # for the states)
I take that back, there is a reflash out that could pertain to your vehicle if the fault code is for EGR system failure. It only pertains to setting a fault where the ambient temp is below 40 degree F and that is the TSB that was posted earlier.
I can't, quick or otherwise. Now go back and read what I wrote about
*any* EGR design possibility. Some vehicles currently driving on the road have both a vacuum-operated EGR valve and a position sensor. Now read the message I was replying to, and imagine if one were to think that, just because one had a P0404 code, then one could not have a vacuum hose somewhere in their EGR system. (any make, any model, theoretical or otherwise)Damn, are you *that* thick? Read the message I responded to. The key "word" is even in capitals. You did quote both messages.

No surprise there...

The OP wasn't talking about *any* EGR design possibility, I believe he was talking about a Dodge dealer. On a Dodge, a vacuum operated EGR and an EGR position sensor would be mutually exclusive.
I see you don't get sarcasm either. I won't bother explaining.
I never said I could, so why would there be a surprise at any cost? I know the OP referred to a Chrysler product. I realize there is some wisdom in maxpower's point regarding non-vacuum controlled EGR valves and a P0404. Unfortunately, he (you?) is dimwitted enough to never consider the big picture as evidenced by a great number of his posts. His attack of claresnyder(sp) was pretty weak, but expected. Again, read what I said and find any technical fault with it. You can't? Great.
vehicles currently driving on the
Again, no shit. Did you google that info? Are you sure of it from real world experience? I'm *fairly* certain that it's true, enough to not bother arguing (on Chryslers) but wouldn't rule it out completely. Of course, I hardly touch Chrysler products but still understand that generality off the top of my head. Don't own any, have only a few in my circle, don't see them or care obout them. I would be emabarrased for any Chrysler enthusiast/mechanic that
*didn't* know that. BTW, there were plenty of different control systems introduced from joint ventures such as the Diamond Star badged imports which could show up at a "Dodge dealer". Do you know if all of them (including pre-1996 California quasi-OBDII models) were devoid of vacuum EGR/lift sensors?I'm certain your question was one of intentional sarcasm. Its wittiness was multifaceted and gay.
Toyota MDT in MO
Technical fault? No. Irrelevant, considering the OP was talking about a Chrysler product? Yes!
If you want to use irrelevant posts to take weak shots at somebody 'cause you don't like 'em, then knock yourself out. I was just pointing out that Glenn was right, and your post didn't make any sense in the context of this thread.
vehicles currently driving on the
No, but you may want to give it a try.
Yes.
Yes.
Such eloquence!
Correct. I wasn't attempting to be relevant. I can't do that 24/7
365.
I already conceded that -however- knew it when posting. I've been pissy on NG lately and it shows. Oh well, life goes on. FWIW, I feel Glenn is a real asset to posters regarding Chrysler help. I have deliberately scrolled right down to his replies for years, but take issue with the manner that he (occasionally) jumps on people, in the sense that he gets bent really easily. He doesn't always see all sides to the issue, and rather goes into tunnel vision attack mode. He's never responded to me, even in the beginning when my replies were of the kinder, more collaborative nature. I guess that my posts, both good and malevolent are blocked, ignored, don't show on his reader, whatever... and life goes on.

Google wouldn't be my choice for auto info, especially trying to determine which vehicles in the Chryco lineup, if any, ever came equipped with the aforementioned combination.
That makes one of us.
Now *that's* proper sarcasm!

I read all the post's and dont block any of them out. I have just as much right to say what I want to say as the next person. I will NOT get into Bullshit discussions that come out of what is said on here. I dont have time for that. The fact is, the OP made it sound as if the dealer was supposed to check his vehicle out for free. We dont get paid by the hour we get paid by the work we do. Just because the OP was told his EGR valve was bad by another dealer does not mean the dealer is going to replace it. The OP has purchased a low line service contract that does not cover EGR valves therefore if he wanted it checked out he would have had to pay for it. Most people I find on here that cry do not tell the whole side of the story. You would be surprised of how many e mails I get from Posters on here about there issues. They dont tell the complete story that was acually done to the car to try and fix it. A vin number tells alot about the history of a vehicle and the work that has been done to try and correct a problem. I forget who said it.... but the OP's vehicle has an electronic EGR valve. Unless you acually get the scan tool out and run the monitor to check it, which means driving the vehicle under a certain speed and a certian load you can not test this device. Once again, it has no vacuum hose to it. So what I said in my first post was merely making a point that the OP was crying NOT FIXED when he did not want to pay to have it checked out after the Independent shop blew him off to the dealer. I only work on Dodge and Chrysler Products and that is what we were talking baout therefore I had no reason to answer the question about other EGR valves on a different Manufactures vehicle.Once again, i do this as a favor to those who have a ligitmate question or problem. I spend alot of time researching and going thru wire schematics to answer questions. I dont have time for the bullshit that goes on such as this thread.

possibility. Some vehicles currently driving on the
Thanks for replying. Many dealer techs work on a wide variety of vehicles which usually comes from their mass of trade-in resales. I guess your shop is different or you have one specific guy to do that work. Your dealer doesn't sell the Jeep line?
Toyota MDT in MO
We are Chrysler only, we do have 2 Jeep Techs because we due tons of work on those vehicles, We are not able to get the Jeep franchise because a dealer down the street has it. I have worked on Dodge for 20 years but got out of that 7 years ago. We have one technician that works on all used vehicles. He inspects and does the repairs Glenn
