Вставка
- Опубліковано 5 жов 2024
- Come along with Eric O. at the SMA shop as he shows how to track down, diagnose and repair the infamous check engine light on this 2005 Dodge Grand Caravan that has a code P0404 "Exhaust Gas Recirculation Circuit Range/Performance" stored in it. Sure you could slap an EGR valve on it but let's be 100% certain!

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!!
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.
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
The explanation of how the pcm needs to reset for the new pintel position is very important.
Your so helpful Dr. O
I think thats the issue am haveing with the aftermarket egr has a note that pcm may have to be updated
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
OMG that click click, click click! I DIED! :)
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!
Yep 100% best way to see if it is working :)
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
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.
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.
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.
Good tip :)
Thanks for showing us that position sensor bypass test. There must be a voltage sensing circuit within the ecu. Awesome egr load simulator!
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.
Haha we all have our trolls! Thanks for the vote of confidence too :)
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.
😲😲 never a dull moment I see... I hope you'll have a better Christmas 2021! 😁😁
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.
Excellent demonstration. Dude, your video editing and camera skills are insane. Really, really good. Thanks Eric!!
Nah, just a mechanic, not a camera guy lol
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.
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.
Thanks for the great video on troubleshooting the EGR on the 2005 TC van, have a great day Sir.
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.
I Imagine the cheapest will be around a grand... just a guess.
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.
The DRB is a very powerful tool. One of the best out there IMO
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!
you know Eric you should do a live stream on a engine replacement that would be really cool
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?
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!!!!
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.
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!
You sounded exactly like a torque wrench, very good. As always a pleasure to watch the vids.. Thanks.
SMA Vid in the Morning! It's gonna be a great day!
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?
perfect timing, 7:30pm Australia, just sit down and bang notification received!
Love the "Old school". Hit with the hammer. Great video. Thank you.
Love It when you introduce the "Good Stuff"! Cracks me up every time! Keep up the Good Work!
erics favorite car to work on.
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.
Well done Eric! Way too common of an issue on these 3.8's. The DRBIII looks like an antique! ~Mike
Where was my Wells EGR when I needed it! I know you liked the BWD comment huh? haha Thanks Mike :)
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
Wells Vehicle Electronics Hey Mike. I see you follow Eric O.
He's the best
Hey Richard, for sure I do. Love watching Eric O's stuff! ~Mike
Another tremendous video I'm learning from you guys thank you for you time.God bless you.
I see your working on the civic. Can't wait to see what the head gasket looks like.
EGR valves on Ram trucks are a nightmare...lay across the engine against the fire wall, try to bolt the tube back on while taking turns going at it from the top then from the bottom then drop a bolt lose it for 10 min in the suspension...haha
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.
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.
I love the brake parts cleaner intro sound! Love it! Love your channel!
The man who is putting tech schools out of business does it again. Kids save your pennies. SMA is where is at.
Wow very good Eric yikes are great mecanic we learne every day with you thakns for your time
Like how they measure some things in metric and then you see in/Hg for pressure
EGR valve: a must for any high mileage Caravan owner.
Having had this code trip on my van and I fixed it by cleaning it...
@@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.
@@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
Wow, that's a piddly little EGR valve! I drive a 1.5L turbodiesel and the EGR is way bigger and beefier.
70k your on your way to 100k I knew it would grow 10 k a month . Top notch content
nice sound effect for brake clean
Very professional diagnostics.
I put 3 on my 05 they do give me a life time warranty
21 years at Dodge from 1989 to 2010 i used the heck out of that DRBIII
What a fantastic tool!
love the videos my friend. you are truly a blessed man...
Dealer: Make sure you install OEM parts only!
Customer: OK, Sell me a new OEM EGR valve!
Dealer: We don't carry those. We can order one for you - it will be here in two weeks.
LOL,I worked in a GM parts dept. and there idea of OEM was to go to Napa,and charge you for OEM.
I was in my local toyota dealer's parts dept the other day and they were getting a massive delivery from o'reillys. Including bulk o'reilly oil and filters. I'm sure they charge OEM prices for it.
It's on Intergalactic backorder.
What ever happened to the old slant six engines? They didn't give you anything special but just would run forever. HMM. Thanks again for another great video.
BMW uses a slant 6 in many of their 2.5, 3.0 cars and truck. I know you are talking about the Chrysler slant 6 of the 60's.
Upallnight That's the engine that I'm talking about slant sic from the Dodge Dart and so on. I had the dart and ran the crap out of it and it just never gave up I don't think they make engines like that anymore.
When Eric made the torque wrench click 😂😂😂😂
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.
Haha for sure... oh and it happens to all of them :(
Very good explanation thank you quite helpful keep up the good work and you’re kind of funny broke when delivered
BWD = Breaks Within Days / Broken Without Driving / Breaks When Dangerous (middle of rush hour highway)
haha perfect!
Broken When Delivered
Great fix and demo.
Love your pneumatic torque wrench
3 ugah duggas and you got it
Another homerun test don't guess thank you Eric
Nice & thorough! The DRB reminds me of my first cell phone! Can you play 'Snake' on it?
One Auto, sure you can haha oh your new door looks great :)
Haha kinda does look like that huh!? No snake but my new Vantage pro you can turn it into an etcha scetch :D
I thought it looked like a Tech 2.
SATAMAN Schmidt yeah I thought that to.
Awesome video! Lots of helpful info
very good sound effect Mr O hmmm
Factory scan tool
Factory torque specs
Factory parts
......well 2 out of 3 ain't bad.....
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
Are you able to get Standard Products? I have had decent luck with those EGR valves on these vans. Done many of them.
Nick Palmer BWD, Echlin, and Standard are all the same company... Wish I could get Wells a bit faster.
Harr harr the old Chrysler tool looks like one of those Weyland-Yutani Corporation computers from Alien.
Ah, the familiar wail of the ol' DRB. That sound haunts me in my dreams.
I had to replace an EGR valve on a 2001 Astra but I had to make 100% certain that it was the problem. I was able to have a laptop connected to the OBD2 port and when the problem occurred it was showing the EGR valve working intermittently so I knew it was the problem. I replaced it with an OEM unit made by Delphi (I was able to source one at a reasonable price) which is still going strong to this day with the car's current owner (it now belongs to my partner's daughter and her hubby). The aftermarket ones are a waste of money. I hope this one won't bite you.
Hey Eric O another fun video beautiful image now in 1080 p/60 best regards Jo
good diagnostic amigo excellent
I have a 2005 Pacifica that is throwing a p0404 that the dealer's mechanic can't fix (I just bought this car and the last time their 3rd party mechanic tried to work on it, they had it for 3 weeks and called me to come get it as they can't fix it and are refusing to work on it anymore as the dealer isn't paying them after multiple misdiagnosed "fixes", including replacing the cat). One quirky symptom is that the code will sometimes clear when I gas up the tank. I got it to clear one time just by taking the cap off and putting it back on again. The clear on fillup only works when the system is cold. Someone mentioned to me about a similar problem in Nissans that requires dropping the tank to fix. Also, this Pacifica has the problem of the saddlebag gas tank going from half full to empty (something about a crossover pump or hose not working or plugged so it's not transferring gas to the pick up on the "top" half of the tank). Does this sound familiar?
Tune in for parts 2 thru 5, where Eric O. extracts the broken EGR bolts, then must Heli Coil 1 of the bolt holes, then removing the exhaust manifold- to have the crack welded that was caused by a broken bolt...LOL
Hey Eric always thankful for your videos. Iam getting ready to expand my scanner capabilities. What do you think of Autel ds708 . I would like to go snap on but Autel seems like a great deal and seems to have great revie,we on Amazon.
Another Great Video.. Thanks Eric....
Hey Eric. My wife had a 2007 Grand Caravan and I replaced the egr valve three times over 7 years. Everything on that van from the water pump, rear AC, egr valve, warped rotors, sliding door harnesses, door actuators, and suspension parts failed at some point. My only thing that I never figured out was the disappearing quart of oil every month and all Chrysler would tell me that it was normal losses on the 3.8. Did you see this or find the solution to the problem? I only heard that some of the engines were assembled with piston rings upside down.
pour in heavier oil add motor honey, or best yet replace the vehicle :)
Chrysler 3.8's all use a qt every 3k. Atleast the ones I work on :)
+kj197734 It sounds like my 07 Caravan. The only thing I haven't replaced yet is the EGR valve. They all use a bit of oil as they have low tension rings for better fuel mileage. I don't think it worked.
That sounds completely normal kj.
I think you already know the solution to your problem.
It's funny, I've looked and looked on my 2004 dodge dakota for an EGR valve but I don't think there is one. They're kind of hard to miss it's a steel pipe going from the exhaust manifold to the intake/throttle body with the tin man's schlong attached to it. Guess we don't care as much about emissions in Canada XD
Thanks Eric.
Cross thread is a natural form of loctite. Lol
I have a 2006 Dodge Grand Caravan 3.3l with 73k miles. I replaced my EGR last Fall and did not do a relearn. Would this cause further issues? I've been driving it and no code lights. Thanks for the video Eric.
Replaced a egr just 4 days ago.... Volkwagen Routan aka ''Caravan''.... egr tps voltage at 4volts flat, 0% duty cycle with the new one.... 3.8volts is what i got for the bad one.... Symptoms was: intermitent stalls at low speed, loss of power steering and code C121C in abs module....
Who doesn't love a good dose of brake cleaner?Excellent torque specs Audi.about those pesky thumbs down trolls,WTF?
sexy scan tool. Good video, thanks.
Torque to spec ;) "CLIK, CLIK, CLIK"
most places that's airgun tight :)
Eric faked that really well. I'm looking at that damn ratchet and saying "That's no torque wrench." for awhile he had me fooled
Two clicks of the knuckle.....perfect!
I was just going to ask where he purchased the flex head slim torque wrench! How did he fake the sound? Was that done post-production?
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 .
Carlos Dorantes he was using it as a jumper wire to ground. Therefore pulling the voltage to 0
awesome u have all the great tools.
Hey Eric
Great vid! Have a ?. Where did you pick up your DRB? And did it come fully up to date?
Thanks!
Hi EriC O, another great one THANKS FRIEND
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.
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.
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.
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!
Thanks
Sry hit post by accident, any ways I was wonder if deleting my egr would help on carbon build up. It seems like to me I have to clean my idle air control valve at least 2 times a year . The truck has a rebuilt 302 efi speed density roller motor . I see I can get a egr block off plate .. thx for your videos they have helped me work on friends an family cars . Being a hvac tech im not the best with autos!
Might you recommend a cost effective bi-directional scan tool for 2010 and 2011 G. Caravan?
I replaced the EGR valve like 7 months ago. The same p0404 code came back again today. What would you do in that case?
I think this was the Chrysler product that after removing the cowl you can remove the wiper assembly as a whole, to get to the rear holes you had that in mind with the caravan engine swap right? lol
I think you are right
Careful, you will get Sprinter owners showing up for repairs. I'd try but It's a long way from WA state.
No way haha I turn down sprinter work
looks like a cell phone i had in 1992
Looks more like my OTC TPSM.
Great video
The bolts on my EGR are totally frozen. So looks like I will just live with it. I will return it. I do have some missing on 4. My valve cover gasket is leaking like a river and flooding the spark plug cavity. Will replace the alternator and valve cover gasket.
Isn't there some kind of cleaner that the car owner can put in the tank to clean the EGR while driving?
Chrysler would have the world's lamest OEM scan tool, do you have to pull start a dial up modem to update it too?
Hey Eric, on pink/yellow wire where you measured 5 volts, my measurement came 8.7 volts. Could it be another problem than the EGR valve? Thank you for your video! very helpful!
Maybe try to clean up all the ground connections, could be high resistance path to ground pushing up voltage readings..
