Dodge Caravan / Chrysler Town & Country EGR Code P0404

[@avnut7]

I have an ‘07 Grand Caravan 3.8 with 186K miles. Just replaced the cat. Now I have a P0404 code. I replaced the EGR Valve once in ‘21 but I’m pretty sure I went cheap. I appreciate you commenting that it’s a normal fault. I will try my hand at using a test light. I will also disconnect the battery overnight to ensure everything resets. I didn’t know about that. I sure appreciate your channel and videos. I know my van is dorky but I really love it… and it’s paid for. Thank you very much!!

[@paullabrecque1307]

On my 2006 Dodge Caravan I change my EGR and it was ok for awhile and code came back, so put in a factory EGR. And that lasted for two weeks brought to a shop like yours and he said it was a block exhaust system that was making the EGR. Act up,found the. Blockage in the cat replace it been good ever since.

[@aboutmyfathersbusiness8324]

You had me fooled for a second with that 1/4 inch ratchet "torque wrench" with your sound effects haha Thinking that is the smallest torque wrench I have ever seen... You should also do a class in video shots and editing. Great quality. Keep it up Dr O

[@toysareforboys1]

OMG that click click, click click! I DIED! :)

[@rrmech11]

The explanation of how the pcm needs to reset for the new pintel position is very important. Your so helpful Dr. O

[@trublue2319]

I think thats the issue am haveing with the aftermarket egr has a note that pcm may have to be updated

[@kyhomegarage3430]

Awesome tutorial on Chrysler EGR testing. Very well done Eric. I don't think that anybody could do better job yet somebody gives you thumb down. I don't understand what else they want. Keep up good job. Cheers.

[@SouthMainAuto]

Haha we all have our trolls! Thanks for the vote of confidence too :)

[@cobraninetysix3883]

Great video...., went aftermarket on my van and sure enough, light on within a month while driving to FLA. got back, put the OEM in and haven't had a problem in two years. Swapped out the ten millimeter mounting bolts with allens! Great diagnostics! Two thumbs up

[@mightyclos1984]

Thank you Eric! I come to work this morning and first car of the day is a P0404 on a magnum. Thanks to you I could 100% confirm it rather than my usual 90% lol

[@Sandbag1300]

Awesome video. Tremendous nugget of knowledge at 24:15 - watch the manifold pressure reduce as the egr valve opens. EGR diagnosis is tough because in many cases you cannot determine if it is sticking until the DTC light goes on but now, watching the MAP read out you can!

[@SouthMainAuto]

Yep 100% best way to see if it is working :)

[@baxrok2.]

Excellent demonstration. Dude, your video editing and camera skills are insane. Really, really good. Thanks Eric!!

[@SouthMainAuto]

Nah, just a mechanic, not a camera guy lol

[@frugalprepper]

SMA Vid in the Morning! It's gonna be a great day!

[@izzycamaro]

Thanks for the great video on troubleshooting the EGR on the 2005 TC van, have a great day Sir.

[@rollingrockfan2482]

Money light brake clean and dramatic music! another great video love the way to go all out to confirm what is what is wrong, before replacing anything, need to find a digital rope scope.

[@zfiddy]

perfect timing, 7:30pm Australia, just sit down and bang notification received!

[@SPdesi1]

Very well explained. Thank you Eric. In 26 min. you covered lot, in short after watching your video I should not take more than 30-40 min. to replace EGR Valve on my 2007 Town & Country. Thanks again Eric.

[@dashcamandy2242]

Thank you for this video, our '05 T&C (3.3L) hit 212k a few days ago, and surprised me with a double-whammy of stuck-closed throttle and P0405 on the way home tonight. Just a few days after I popped the radiator in my Camry (340k) and figured I'd fix the exhaust system while waiting for the radiator to come in... And snapped two of the 3 studs at the manifold flange, so the radiator arrived before the new exhaust manifold that I now had to order. And a few weeks before that, my '01 4Runner punched a shock right through the shock mount. MERRY FREAKIN' CHRISTMAS TO ME, 2020 can't end soon enough! (And yes, I just ordered a MOPAR EGR valve for the van, because I prefer to make repairs ONCE.) And you're right about BWD. In a matter of three months, I went through 7 - SEVEN - BWD mass airflow sensors. Some of them lasted a few days, some a week or two... Bought Delco and drove that car another 80k until the intake manifold gaskets blew at 238k. And my '88 Cutlass Ciera? Oil pressure gauge sending unit, from BWD, lasted four days before it made my gauge do some crazy pinwheel actions, and I pulled the plug on it. BWD Park-Neutral switch? Dead on Arrival - no backup lights unless I went from Neutral to Reverse - never from Park to Reverse. Sometimes the backup lights would flicker if I shifted to L1. BWD Coolant Temperature Sensor? Well, I fixed that issue with always running Open Loop for a few months, before that failed too. Before I could fix it again, a drunk driver totaled me out.

[@armoricain]

😲😲 never a dull moment I see... I hope you'll have a better Christmas 2021! 😁😁

[@richardcranium5839]

i looked at the title and had to check the calender to make sure it wasnt april fools day was expecting Eric Goes Rougue with a 404 error page not found , lol. great video as usual. when returning the screws in plastic its best to drop the screws in the hole. the SLOWLY turn counterclockwise (backwards) until ya feel it drop. then ya know for sure you are in the original threads.

[@SmittySmithsonite]

The wife and I almost stopped by your shop yesterday to meet you and Vanessa to say HI, but we were short on time. I had to deliver a Lexus out to Buffalo, and were going to swing down 390 there on the way back, but unfortunately we were on a limited time schedule. I have a case of Wearever Brakeclean with your name on it as a THANK YOU for all your help in the vids, and in the comments section - I'll get out there one of these days. :) Now I see why cars rust the way they do out there. HOLY CRAP I have NEVER IN MY LIFE seen so much brine on a highway EVER!! Thruway was PURE WHITE!! Wtf!! Had to scrape that crap off my trailer lights whenever I stopped! I hit the pressure washer in my town on the way home, so my stuff will live to see another year, lol. And boy are those troopers sneaky, sitting in the median there waiting to pounce - I think I need a brake job now after the 10 times I had to jack on my brakes from 80mph ... HAHAHA! Wow that DRB is massive! Electronics sure have come a long way ... or maybe not (freezes up, LOL!). Loved your Loctite / cross thread comment - I almost hosed the iMac down with coffee! :D Getting hammered with snow here now. Brunt of the blizzard is just hitting us. Stay warm digging out, brother!

[@fielding68]

Love the "Old school". Hit with the hammer. Great video. Thank you.

[@dougb7843]

Thanks for showing us that position sensor bypass test. There must be a voltage sensing circuit within the ecu. Awesome egr load simulator!

[@JLRJ]

Love It when you introduce the "Good Stuff"! Cracks me up every time! Keep up the Good Work!

[@wysetech2000]

I like the comments about the DRB being "old school" It was better than any other scan tool in the day for Chrysler. It was prone to freezing however as it didn't like minor voltage spikes at all. Well done video, Eric.

[@SouthMainAuto]

The DRB is a very powerful tool. One of the best out there IMO

[@holymiumtv7560]

I laughed at your comment about bwd parts. just replaced my mother's egr valve on her 2010 caravan for the classic p0404 code. circuit tested fine, position switch was sticking. used a bwd part, lasted two months. waiting on a Chrysler one from the dealer. good video though on a common problem we see in the shop.

[@63256325N]

You sounded exactly like a torque wrench, very good. As always a pleasure to watch the vids.. Thanks.

[@baddriversofnorthtexas6850]

erics favorite car to work on.

[@clintho1]

I love the brake parts cleaner intro sound! Love it! Love your channel!

[@timwilson3150]

Had code P0404 on my 05 Ram last year and replaced the EGR with an aftermarket EGR that I bought at O’Reilly’s. Here I am a year later with the same P0404 code. It had 89k miles last year when I replaced it and it now has 98k miles. So yeah, go with OEM when it comes to the EGR valve on a Dodge/Chrysler vehicle.

[@godsmack113]

you know Eric you should do a live stream on a engine replacement that would be really cool

[@oscargonzalez8518]

Another tremendous video I'm learning from you guys thank you for you time.God bless you.

[@GoTechTraining]

Well done Eric! Way too common of an issue on these 3.8's. The DRBIII looks like an antique! ~Mike

[@SouthMainAuto]

Where was my Wells EGR when I needed it! I know you liked the BWD comment huh? haha Thanks Mike :)

[@GoTechTraining]

Wish you had our stuff more readily available to you. We made some pretty nice improvements on that valve to helps its longevity.And yeh, that was a nice comment! ~Mike

[@rrmech11]

Wells Vehicle Electronics Hey Mike. I see you follow Eric O. He's the best

[@GoTechTraining]

Hey Richard, for sure I do. Love watching Eric O's stuff! ~Mike

[@scottfirman]

I had to replacecthe EGR valve on my daughters Chevy Equnaux recently. It was showing the code so we picked up a new one,put it in and run good after that. It really is simple stuff,like you said,if you can do it,we can do it. Good video. I dont remember ever replacing the one in my 04 TrailBlazer. it has 198k on it. I like the simple stupid fixes best,hey!

[@thebandmcomputer]

Thanks for another great video Eric O...I wish someone would make an affordable DIY scan tool that had BI DIRECTIONAL CONTROL. So much better when you can COMMAND things on and off.

[@SouthMainAuto]

I Imagine the cheapest will be around a grand... just a guess.

[@djzorroreno4943]

Very professional diagnostics.

[@alchemy1]

This guy is the best. Totally the best. Definity worthy to subscribe, bar none. How can a person test the solenoid without a scanner, bench test etc?

[@steventenney8797]

70k your on your way to 100k I knew it would grow 10 k a month . Top notch content

[@matthewmorelli3547]

Take the top 10mm out, then take a pry bar between the alternator and egr valve and rotate the valve towards the rear. This not only gives better access to the bottom bolt, but also loosens at the same time.

[@SouthMainAuto]

Good tip :)

[@Mikeissm]

I see your working on the civic. Can't wait to see what the head gasket looks like.

[@TheSourHours]

The man who is putting tech schools out of business does it again. Kids save your pennies. SMA is where is at.

[@Arieeeee]

Very cool. My car's EGR system has a modulator and VSV that I've had to deal with a couple of times and was always wondering why they don't just have the computer control it and cut out the middle man. After watching this video, I'm kind of glad mine is mostly just vacuum tubes that need cleaning from time to time than electronic parts that can go bad.

[@jorgemora7190]

Wow very good Eric yikes are great mecanic we learne every day with you thakns for your time

[@fieldsofomagh]

Great fix and demo.

[@YouSpamTard]

Thanks. Between you, scanner danner, wells, go tech, fordtechmakuloco, and that russian guy with the adhd (haha), I have learned a ton. Recently I got a hantech scope. I have learned to graph with our snap on solus and save the files to a pc desktop for study at home. I got a killer ford explorer with the same symptoms as a taurus you worked on that I can't figure out. I am not even sure if its a misfire, an engine airflow problem, or maybe even a transmission problem. EEEk. On the Caravan we have in our shop now, I did all of what you have done here and everything was good, so I put in an egr valve. It did not respond so I cleaned the old one and re plugged it in and it did respond at least some. Its a made in china part bad right out of the box is what it is. You buy two egg rolls and you buy two egr's. My usual google search would be something like "tps repair south main auto". In the last month I nailed three correct diags for pcm replacement. I got a buick enclave or whatever it is to work on tomorrow and it has a key code p3055 and a no communication with ecm u0100 and I bet I know what "direction", as you say, to go. Description of operation first and code setting criteria second. I learned this from you. Thank you sir.

[@martystevens3969]

On a Dodge Caravan, remove the top cover and unstick the valve. Bend the tabs over on the top. File down some of the bracket on the back of the alternator bracket to make it easier to remove the EGR bolts later.

[@opl500]

Like how they measure some things in metric and then you see in/Hg for pressure

[@TheToadkicker]

21 years at Dodge from 1989 to 2010 i used the heck out of that DRBIII

[@SouthMainAuto]

What a fantastic tool!

[@danewman4me]

I owned an '06 Dodge Grand Caravan with the 3.8 liter. We bought it at 40,000 miles and it would use a quart of oil every 1,500 miles; no smoke, no fouled plugs, and no drips. Dealer told me it was within acceptable range (1 quart per 1,000 miles). The forums also talked a lot about 1/10th of the 3.8 liter motors using oil. Have you seen this at your shop?

[@jameskirby9369]

I used to use a quart every 1000 miles on my 08 town & country. Turns out the valve covers were leaking but it never leaked to the ground and didn’t smell like burning oil. I haven’t been losing any oil since the valve cover gaskets were replaced...strange!!!!

[@cwilsonpa]

Nice job ! I need to do mine now. I think I'll take it to my local independent auto repair shop with the oem part of they can get it. Keep the videos coming. BWD (Broke When Delivered) I like that...sad ,but true not the best parts.

[@adventureoflinkmk2]

Having had this code trip on my van and I fixed it by cleaning it...

[@brianoconnell7266]

@@adventureoflinkmk2 What's the best way to clean it? I have that code now and would rather not but a new egr if I can help it.

[@adventureoflinkmk2]

@@brianoconnell7266 what I did was use carb cleaner and spray inside the port of the EGR. Of course I let it soak in there for a little while, and the straw attachment is your best friend, USE IT. Then of course you take some brakleen -- not a sponsor -- to clean any residue that the carb cleaner leaves behind. Worked just fine for me, no P0404 or P1404

[@jimmydeen58]

Another Great Video.. Thanks Eric....

[@mrred123]

I did the key cycle trick on the Town and Country 2010 and there were no codes but the money light was on.. last code before cleared was when I change the EGR myself it was the same for 04 code

[@spelunkerd]

When my scan tool locks up, I cuss and wish I had a non-PC based, OEM tool. So, it's interesting to see the same thing happen with a Chrysler stand-alone tool. Gotta love your torque wrench, ha ha.

[@carlosdorantes9286]

One question when you test the signal return with the test light , why the test light has to be attach to ground and not to power? Thank you are a great guy .

[@inkheart1892]

Carlos Dorantes he was using it as a jumper wire to ground. Therefore pulling the voltage to 0

[@mikedayitt]

looked like an idle control valve. I bought one on my tarus wound up being wrong type car would idle at 40 mph. Call ford they said they had changed to configuation on my type car . Found one that looked like the one I had and car runs great. One issue I did do and I dont know if I set it right tho, The screw that adjusts the air flow on the throttle. I set up my scanner tool and turned the screw(because dummy me not thnking that may have been it) anyway set the screw til it touched then looking at scanner which reads in percentages turned the screw from 16% all the way closed til it moved it to 17.3% So not sure if that is right but thats where I got it.afraid to open it up anymore.

[@richerichusa]

how long should you disconnect the battery so it doesn't remember old number ?

[@andrewquintero7590]

What is that air power tool you used to remove the bottom bolts?

[@alchemy1]

How can a person bench test that EGR valve 2005 town and country? Can a person supply 12 volts directly to the solenoid wire (6) and ground (4) to the body? Would that cause the valve to open, just to check to see if the valve opens or not? I am wondering how could I bench test it?

[@comingundone27]

Are you able to get Standard Products? I have had decent luck with those EGR valves on these vans. Done many of them.

[@steveingalls6798]

My 09 3.8 T & C sets a P0404 every time Mama drives it because she treats the gas pedal like a kick drum. She never uses cruise control. Whenever I drive it this P0404 code never sets ? Not sure whether to investigate the EGR or not ? I just clear this code & drive on.

[@haywardsautomotive6156]

New toy DRBIII? How's it been working? What air ratchet is that...did you ever get your Astro back? Nice quick diagnosis & repair. Do you have an Auto Zone nearby b/c some of their Duralast parts are made by Wells & are actually Well products rebranded with Duralast PNs? Found out that lil tidbit of info when a mouse whispered in my ear. Their Duralast EGR valves for the Chryslers is made by Wells which I didn't know until a few weeks ago. I was staying away from Duralast b/c I didn't have good luck with them a few years ago but when I went to get a Duralast MAP sensor from them b/c the dealer was out and inside the box was a Wells. I thought someone put it in the wrong box & I got a gift. Now I go to all their Duralast parts and look at the description and if it's made by Wells and they have it I actually prefer to use them over OEM.

[@29auto30]

Duralast products are engineered and manufactured by Wells Vehicle Electronics, a leading global supplier of advanced vehicle electronics solutions for original equipment and replacement applications. Every component either matches or improves on the OE design to ensure fast, easy installation, superior performance and reliability. Wells offers extensive application information and technical support via its Tech Line at 1-800-558-9770. This is from Autozones website,did not know that thanks for the info.

[@haywardsautomotive6156]

Not all Duralast products are Wells only some of them. You have to go into the Duralast description and if they are it will say so and when you open up the package you'll be greeted by the Wells name. Wells IMO is better than OEM and I've never had a Wells product fail!
