Chevy Truck: P0449 EVAP Vent Valve Performance
HTML-код
- Опубликовано: 13 сен 2024
- In this video I have a look at a 2005 Chevy 1500 that came in with a P0449 EVAP Code. This is a pretty common failure in our neck of the woods and a really easy fix. - Enjoy!

Mr o how much to do my 57 Chevy brakes wires n all I got sum new tires to put on made for track n street I'm in ellenville ny
Thanks Eric!
This is very helpful. Thank you! Will this same part number work on my 03 5.3 Silverado? I ask because Amazon says it doesn't. Thanks!
Thank goodness. A real mechanic video. I've been watching too much of Scotty videos, he's not a mechanic, he's an opinionist. I like watching videos I can learn from. I've been working on vehicles for probably 45 years, and I am good with the electronics. But you are a very smart and factual person.
I've been watching too much of scotty as well. Just remember he always tells the truth, even though the truth is just his opinion backed up by no evidence.
Scotty is what I call a hack
I have probably watched 50 Scotty videos never once saw him pick up a wrench. You can see he is webcasting from his backyard garage full of junk clearly it is not a real business/repair garage It's always the same schtick .
I just can't listen to Scotty, no matter what his opinion is. Incredibly annoying man to watch. Stopped watching him years ago and that was only after watching 2-3 of his uploads.
What bothers me most on the Scotty channel is the way he plugs specific products that he doesn't normally use in 'reviews' which are little more than corporate advertising. Any quality review requires a discussion of cost, alternatives, and weaknesses. People who think that Scotty reviews show 'honesty' need to learn a little more about how advertising works on RUclips. The other issue is the way he makes complex repairs seem too easy. For example one of his videos described how to change a timing belt, without explaining how critical it is to match up timing marks before restarting the engine. Walking innocent people into the chance of major repair errors or safety mistakes is not cool, even when presented in a popular format.
I have not watched this video yet but I have watched a bunch of SMA videos over the past few weeks. At 69 I am surprised at the amount of electrical/system/computer trouble shooting that goes on now adays. I am from the points and plugs days. You could see the street when you open the hood. Fixing brakes and axles and mufflers is cool to watch especially when Eric brings out Big Bertha or the flame wrench. I am most fascinated watching the scan tool trouble shooting and current draws etc. As a former electronic and computer tech it very interesting seeing a grease monkey (No negative shade being thrown just an old term) using scans and meters shows me just how much cars have evolved over my life time. Bus communications in a car?? Yep, real cool Eric. Keep up the work, love, LOVE your videos. BTW I can not imagine how much you have spent in tools. Seeing the Snap On Truck guy sell a 100 dollar ratchet blew my mind until I searched for some of the prices for the tools and scanners you use. Love your family and the car give away broke my heart.
basecom70 you have to be an electronic engineer now a days to properly be able to figure out things sometimes
basecom70...something tells me that you haven't discovered the following channels, yet!!
1) ScannDanner. Paul Danner is a teacher at Rosedale tech, in Pa. The cream of the crop.
2) New Level Auto. Keith DeFasio, a mobile tech from Staten Island.
3) Pine Hollow Auto Diagnostics. Ivan is good friends with Eric O and Keith D. He is a very good all around fixit genius.
4) DiagnoseDan. He is Dutch, and I believe a shop owner. He is an awesome tech, and a showman, too.
I hate to leave any out, that likely deserve a mention, but you can find the different channels from each of their channels. There are a few that really rise up above the rest. A few have recently gone quiet, but are still good days, in their own right. Check them out.
Without a strong electrical knowledge its pretty close to impossible to fix a car without throwing parts at it. Most of my time diagnosing involves research. Finding out how the system works, where the connector are located with wire colors, and looking over wiring diagrams. I never though I would use a scope to diagnose, but now its pretty much a necessity for some diagnosis. The test light is still very useful though along with a good scanner. I have to get into programming next to stay competent.
Sure, brakes are brakes still but the electrical is getting very complex.
@@roadkill5333 Thanks for the info. I will check them out. I just like Eric's feel. I just wish he was around here. I would feel good that he is fixing only what he found bad and knew what he is doing.
MR O, don't worry about wasting my time, I'm retired and enjoy your videos. As others have said it's hard to find someone like you with his customers, honest. I have such a business close to me and it's good to know what they tell me is what I need, not a muffler bearing or something like that.
New York weather, North Eastern weather, that stuff is hard on any vehicle, I do t care if it's Chevy, Dodge, or even your favorite, Nison. That weather will tear them all up, and then like you say " not long for car heavn!!!" Nice video Eric.....
Cassius Puckett so true! I am in the market for a truck and am considering paying extra for shipping from the south to avoid all the rust.
People who complain about how much they pay mechanics. Watch this and listen to the knowledge Eric has. This is why he is a "Technician" and a "Guy who works on cars" is a "guy who works on cars".
if you think a good mechanic is expensive.... try going to a cheap one ;)
@@SouthMainAuto Problem is that by the time the customer finds a good mechanic, they are jaded and broke.
@@SouthMainAuto if you think knowledge is expensive.........try ignorance.
The problem is trying to find a good mechanic with solid diagnostic skills like Eric has. So many mechanics out there don't have those skills, so they just aim the parts cannon at the vehicle and launch
Eric is not the normal Mech. He has a work ethic that u don't see much anymore. I do have a problem spending a lot of money on a mech. that can't or wont fix the problem without just getting out the parts cannon and sticking the unnecessary costs to me. Another reason to watch Eric is to increase my knowledge so as to hopefully prevent being hosed by a mech. and maybe help me chose a good one. I was a fleet manager in charge of a large fleet of cars and I could rarely find a mech that knew what they were doing. It was so frustrating. One time I took a car to several mech and dealerships to fix the air conditioner. One dealership flew in a specialist to fix it. They could not. I had to drive this car and my ass was burning and went to internet in search of a fix. The fix turned out to be low engine coolant. The levels on the overflow were spot on but for whatever reason it needed more, about 2" past the full mark. Then voila it worked from then on. I only wish Eric lived by me. I sometimes wonder if he understands how rare people like him are now.
I always enjoy your videos, and this is the channel that I watch most of the time. The thing that really bother me is that automobiles are overly complicated; it's just scary. I do admire the work of true artist.
Always nice when you've had to deal with the same problem and able to solve it quickly and efficiently. I think they call it 'experience', lol. Thanks for sharing.
you are a good man with a good sense of humor and very knowledgeable too.thank you.Kostas.Athens,Greece.
I like the fact that these error codes have four digits, because 999 possible problems aren't enough.
What a great way to start a Saturday with a SMA video. Thanks.
Thank you for the lesson Eric.
Yesterday I was at the Ikea in Hicksville on Long Island and saw a young fella wearing some SMA swag!
Same in Florida lasts 2 years on dusty roads either style. Last time I bought 2 of the cheap ones(ACDelco 214-2149) and put the spare behind the seat. It's a way for GM to make money instead of lose money on a recall, must be the new math. Thanks Eric.
Your videos are so in depth.. thank you for passing on the knowledge....
Just recently discovered your channel Eric. As an european self tinckering guy we don't have your cars a lot but love your sence of humor and i still learn a lot:)
I just started "binge" watching your channel. Nothing is getting done around my house this weekend.
Love the content, the way you go about the repairs, and explaining them. Learned quite a bit already.
Keep up the great work, very entertaining.
Eric,
Great video, diagnosis and fix! Aint no Sliverados in my future but I still liked the video and learned something :)
SMA#1
God bless
Paul
Once again Mr O,
Problem solved and very informative looks like a pretty simple fix Great job keep the awesome vids coming
Eric Thanks for mentioning the year and mileage at the start of the video some of us decide what makes and models to buy based on how durable or difficult to repair these vehicles are.
GM's fix looked good on paper, however, the real world tells a different tale. Kudos on finding a cost effective work around for your customers. They are Blessed to have you, Dr.O. Excellent vid, as usual.
I really liked how that scanner displayed the information so I went to amazon to check the price out.. I guess I’ll only be able to enjoy it through your videos :D
Ford had a similar setup on the 02 03 Expeditions. The vent valve's in the back of the vehicle, you run this flex hose up to the front by the brake master cylinder with a small filter on the end. I did that once, never again! Great Video! Keep up the good work!
Watching your videos motivated me to change my own heater core in my 2007 colorado. Misson accomplished. Thank you sir
This is one of the few situations where having a scan tool with bidirectional control is critical. One day, can you give us a discussion of how you might approach this problem if all your scan tools let you down?
Oh that is a good idea!
You could get pretty close to 100% diagnosis without a bidirectional scan tool on this one. The scanner makes it so much easier to diagnose, fix and move on with life.
In this case just doing a resistance check on the solenoid would likely have told you it was open. Might have been harder to verify there were no other EVAP problems though - other than just clearing the codes and seeing if any come back.
Good job I really like your detailed videos to get the repairs done right. Happy New Year to You and Yours.
Thanks for the video and explanation, Eric. Happy New Year to you and Mrs. O and the entire SMA Family. ❤️️
Thank you for buying our solenoid vent valve, Eric.
Rusty buggah. Haha "Chevrolet heaven" that made me chuckle. I get my truck oil undercoated every year. Doesn't look pretty but my God makes working on them soooo much easier. Merry late Christmas to you and your kin Mr. O. Here's wishing you and yours a safe and prosperous 2019. Rudy from NH
I have same problem in a 04 Silverado thanks for walking me through it when the weather gets better I'll change it
Happy New Year to you, Mrs. O, the kids and the dogs.
I feel the need to say, until recently when I viewed this channel I would have sworn Eric said "Welcome to the Self made Auto Channel". OK, now I know...... :)
this video will not be Scotty approved you actually fixed something in good detail , thanks for the lesson
I may have watched this on new years a bit under the influence................... WOOOOOO!
The best on RUclips. And I've watched them all.
Thanks for mentioning miles on vehicle, happy new year Eric, you have a kind heart, enjoy your videos
Thank you very much! Happy New Year to you and your family 🍾👍
Another great SMA video! I'm going back to sleep. Thanks Dr. E.. Take care!
Love the SMA archaeology course where you explore fossilized transportation in your region Prof. O! Really like the fossil scales of the Tranasuarus Differential!
I love living in the south. I have a 2006 silverado not a spec of rot on it and hopefully I'll be able to pass it down to my son one day. I love my truck and yes I have had to replace the vent canister once about 5 years ago and still going strong. No I did not relocate the filter either.
Another great video, this code just popped up on my 14 Silverado yesterday.
Another typical terrific video from Mr. O. Thank you!
Local newspaper does NOT print a Saturday edition anymore. No problems. I can share my Saturday morning coffee time with Eric O. Great job on the heaven bound 1500.
Thank you sir!! I’ll be swapping this garbage out asap on my 05’ 4.3L reg cab base model POS Silvernada money pit of what some consider a truck. Lol. Hopefully tomorrow. Anyway, good video. Thanks again for the parts & tools used info.
I have an 03 with a 5.3. Have had the same problem for a long time. Check engine light. Evap code. It hasnt bothered the performance just been driving it. But glad for this video. Now i know what to look for. I enjoy your videos have you thought of becoming a auto shop instructor? I do learn alot from you. Thanks for doing what you do
I had my own go around with a P0449 / P0442 on my Dad's '09 Chevrolet Silverado Z71 4X4, 5.3L regular cab (Northern Ontario, Canada). I'm not an automotive mechanic, though I have worked in the powered lift truck industry for 20 years. The vent control valve (same as the one shown in this video) had been replaced twice with NAPA (BWD?) parts at a certified installer. After the 2nd vent valve, Dad asked me to have a look.
I only have a basic OTC code reader, but it does provide some live data / PIDS as well. I had battery voltage at the solenoid harness, but no way to test the -ve output from the ecu. I pinched off the vent solenoid hose and confirmed tank pressure sensor responding and within the 'normal' range when vented (summer time, about 1/3 tank).
I got lucky.
I reset the codes, substituted my Snap On trouble light for the vent valve and it lit, the MIL light stayed off (usually would come back on 2nd hit on the key). I confirmed battery voltage and the trouble light, good. I checked the resistance of the solenoid, 21.2 Ohms. Seemed high imho for a 12V actuated coil. I replaced the valve with a new OE Chevy valve with the updated harness (17.1 Ohm) and voila, solid for the last 6 months.
Thanks for the lessons and information Eric.
Thankfully it is an easy job on a Chevy truck. I have an '06 Sierra that's on its 3rd vent valve, 3rd blower resistor, 3rd front hub bearings, 3rd set of tires, 4th set of brakes, 2nd set of cv axles, 2nd set of front impact sensors and 2nd headlight switch. And it only has 77,000 miles on it. But they were all fairly easy jobs though. Thanks for the videos Eric. Please post the part number for that valve.
I have been using a fuel injector noid light to connect to the vent solenoid connector to easily check for a circuit problem. Nice and convenient and plugs right in. It also works on quite a few other solenoids such as Ford IWE solenoids. I have not used that version of OTC scanner but on other units I believe you can override the graph min and Max by clicking the three dots on the top right of the graph. Good videos, thanks
Great video. Thanks for showing the repair and how to properly use that scan tool.
Hello Eric Happy New Year to you and your family and thank you for the Welcome to the South Main Auto Channel! Your still the Master Problem Solver!
CHEVY THUNDER! 😁
I've learned alot from you and others about EVAP the past year +. If I could only remember the values - what's good & what's bad. I wrote that 1.45v down, because 10 minutes from now I'll be saying, "What did he say? 3.3 volts?" lol
Story time! New ones happen at a moments notice around here lol. So, I took my 18' flatbed to pick up an old, tired & rusty '04 Ram 1500 plow truck for one of my best friends yesterday morning. We took it for a short drive in the woods to unload the rotten firewood and old tractor wheels that were piled up on the wooden bed. The owner had jumped it and got it running for us .. but then it stalled - 15 minutes to get the hood open, then another 10 to get enough voltage into that spanked battery to crank the turd over. Got it going and now my buddy is driving it to my trailer - he's telling me it has NO brakes - and I mean NONE - not even the slightest drag. You can see where this is going ... I look underneath and it's got a blown front brake line, blown rear brake line, and one blown wheel cylinder. SWEET! So I threw some chock blocks on the trailer to keep him from going over the edge and into my truck. The plow hit the ramps, so we had to load her backwards. My buddy is jamming the thing in park to stop as he attempts a 3- point turn in the middle of a well traveled highway here. He's got it in 4 low. Backs up the ramps super slow - everything was going great. Now he was getting nervous as he got closer to my truck. He had just another 8" to go. So he was side-stepping the brake and gas, I guess just out of habit, when his foot slipped and he MASHED the pedal! Thing came right at me - I side stepped, it shoved my chocks right off the edge, and BAM! Thing came off the trailer, landing on my open tailgate by the square pintle hitch receiver! SOB! My buddy was distraught over it - was going to buy me a new tailgate - I told him, shit happens! It's an 11 year old computer controlled beer can - if I'm lucky I might get 5 more years out of it oiling the pee out of the undercarriage twice a year. It actually didn't do that much damage! The pumpkin landed on my winch on the trailer, which stopped the rear bumper 4" from going though my tail lights! It also kept the hitch receiver from completely destroying my tailgate. There's only a 5" x 4" dent maybe a 1/2" deep! It also took out a 1" square chunk of bed liner right down to the primer - not a huge deal at all.
We had to jack the plow truck up and shove my ramps one at a time under each of my rear wheels, then use the load binders as extremely slow come-alongs to pull the truck up and over the top of the ramps, back onto the trailer. It worked, I tied her down, and made the trek 30 miles back home. When I got back, I set up the ramps and just did a no-brake Hail Mary right off the trailer HAHAHA! Luckily my aim was right, and I stayed on the ramps. 😁
Never a dull moment around here! Here's some crappy 11 year old flip-phone pics for ya. :D postimg.cc/gallery/2qlaide2q/
You are the man you should run for president
That rear diff and frame looks like it was raised from the Titanic !! The gods of rust rule in upstate !!
The thumbs-down viewer must have bought the relocation kit! LOL
Chevy Chase...the thumbs down viewers are the ones that make phone calls, and don't get an answer!!
Or they are the kit manufacturers...
@@wammyz - Or employees or owners of Dorman ...
Brian Hensley got it right Bravo!!!
Great idea. You are thinking outside the box. I thought the suzuki fix was pretty cool too. ASE Tech Minneapolis MN
I freakin love this channel!!!!
you are right on those relocation kits .I will get a vehicle in here thats been aroung the Gulf has one of those kits on it ,filter is full of sand vent valve has open winding. I 've installed a few myself years back, waste of time and money. I have as much luck with aftermarket as with GM on those. Good Vid.
No madder what videos you make always good viewing Happy New Year you and your Family.
Thanks again for a great diagnostic video. Thumbs Up
This was a good video interesting and informative
I made a pre filter for mine with an old pair of the wife's panty hose. Works like a dream and is smooth as silk. Change it out once a year or when I get a snag.
James Last I did the same
I found if I do not over fill my 2006 Chevy truck fuel tank, the vent valve does not go bad. When filling the tank, STOP when the pump clicks off. Do not add more fuel. I replaced it twice in the first 6 years. Now it's been 6 years since I've had to replace the vent valve, since I stopped over filling the tank. And I'm in Alabama, it's not just a New York problem.
Great video Eric, I bought a OTC fuel injector noid light just for this test. I will get you the part number today or tomorrow
I got one ;)
I bought a used 04 Sierra and it's got the kit, but I still had the problem too. Love my Cheevie, still. Thanks Eric.
Thanks Dr. O!
Next time you do one of these try moving it beside the transfer case,just lengthen the wires and use a piece of heater hose,this gets it away from road crap,they last alot longer,I've done quite a few that way and it seems to work good
Another job completed
one of my favorites is to start the engine, close the vent and open the purge. That lets the engine vacuum pull the system into a vacuum pretty quickly, then close the purge and it should hold vacuum pretty well. If it doesn't then start blowing smoke. That might be what you did here, I wasn't clear whether or not the engine was running. I've seen here in Chicago more of that style vent valve get moisture in the solenoid portion and freeze, you'll see the solenoid cracked almost in half, than I've seen them fill up with dirt, unless it's a murder truck or something. W body GM's were good for that too (monte carlo, lumina, impala, grand prix etc.)
Thank you for the insight.
Great video Mr. O thanks for sharing always enjoy watching your videos.
Thank you Eric. Happy and Blessed New Year to you and your family.
@9:58+++ lol a that reflection and silly flail wave, I assume you noticed or seen my previous comment :))))
it's amazing how many folks miss that
Great video Eric O
Is it wrong that I almost wish my truck would break down so it could costar in an SMA video? Of course the 1500 mile tow charge might but that dream out of reach.
Im in the same boat. Im in missouri. About 1200 for me
Justin a
Speaking of boats, I’m sure Eric can fix those too.
Hey Eric, better rust protection. When oxygen takes electrons from the iron during the process of rusting iron atoms simply take electrons from the reactive metal. If we wrap zinc around an iron nail the nail is protected from rusting. ... Simply put, the zinc is sacrificing itself to protect the iron hence the name sacrificial anode. Too bad ya can’t somehow incorporate zinc into a spray or perhaps try one of those ship anodes on a truck or car. Might be a neat experiment to test out. Nice video, easy peasy fix and ya made it look even easier. Thanks for sharing that. Oh and they were wrong thinking a gas cap would have fixed the problem. I get told that all the time too
"Hint Hint" OTC, time to update your firmware and give Eric O. more options to use! LoL
Beautiful job
Excellent 👍😀. I'm learning. If you can do it I can do it.
Good work Eric. With me it always ends up needing a smoke test when it is an evap problem and without the smoke machine its hard to find the leak. But good to know I can take an ohmmeter and test the solenoid windings in the vent valve.
Six people thumb downed this video because they either don't drive, know what a car is or couldn't change the vent valve themselves and had to pay someone to do it for them. Suggestion for the next time, take to S.M.A for repairs...
happy new year Eric.
Very good information. I'm having the evap system problem on my 2004 suburban with 324k miles. I replaced the vent solenoid 4yrs ago but I think it has crapped out again.
Way to go Dr O.
Another valuable video. A series covering every vehicle on the road would be nice. And, as you are working on cross-section of the vehicles representative of your area a database of problems/fixes associated with each vehicle type would be something of real value. Too much time for one guy of course. However, no such database exists as far as I know. Which is too bad for consumers.
I run a Ford POS PU for hauling firewood and was considering a GM product. But this video suggests they have issues of their own. I have ran a different manufacturer's vehicle, on salty and dirt roads, and they ran and ran and ran until they simply melted into the substrate. But almost never any mechanical issues. Won't mention the manufacturer because, frankly, there's too much competition for them already and prices are going out of sight. But it proves to me vehicles can be built to be able to withstand a salty dirty environment at least mechanically.
We spend millions if not billions of dollars on salt related vehicle repairs every year. Yet we keep right on applying it to our roads (and waters). Why is that? There are alternatives and they're not that much more expensive if you consider the costs associated with vehicle repairs and damage to our environment. The old safety first adage does not really apply if there are real alternatives.
And then, Dr. O, you could work as a rocket scientist. Truth is you could get a job just about anywhere in the tech field. You do good work.
I have changed those vent valves with the filter built in and I blew out the old filter and added it to the new valve which doubles filtration. Reusing the old filter after cleaning, along with the new filter will hopefully extend the life of the valve. Time will tell I guess?
Thanks for the video.
Not the same vehicle, but my '07 Chevy Tahoe just gave up its vent valve solenoid this year after 123k miles of West coast driving (Seattle area). In these vehicles, they have the corrugated hose tied to the fuel filler neck and the filter pointed up. It's nicely protected behind the plastic bumper cover, but I supposed some amount of water and dirt does get up there occasionally.
Awesome video as usual . Never really thought to use power probe to test a vent solenoid . I usually use both ends of the test light commanded off and on light flicks on or off . But jeez that rust is a killer up there.
Very good diagnosis even I understood Eric could u show us the way u put a car on your lift and a little how u learned just asking
Ive got the 04 silver-rotto. Just did an earl change today. Did not realize that it was that easy to reset the oil counter. But I've ran into all the evap codes. Turns out the fuel pump sending unit rotted away over the summer.
Do a video on that green dodge in the parking lot
Hell yeah!!!🤘SMA on a Saturday morning, with hot coco an toast. 🤘🤘🤘🤘😎😎
Great job! Love even the simple stuff.
Good job brother man! WooEee! That salt is wreaking havoc on that Chevy. Ford fans use to say you can hear a Chevy rusting a mile a way.😆😃
On a more serious note Eric, I was wondering if the purge valve fails stuck shut and the tank comes under a lot of vacuum due to fuel usage lets say.....will the PCM open the Vapor Canister Vent at some point to save the tank from collapsing?
Outstanding video Eric , thanks. Can you share the source for the 1/4" drive long t-handle you used?
The apartments next door HATE the powerprobe noise. I was hoping it was smoke machine time instead.
Scan tool options. In the upper right hand corner of the graph displays there are three little dots stacked vertically. When I see those on my cell phone, they mean that pressing them gives me a menu...I was wondering if you press them could you change the graphing options...? Thanks for taking us all along. fun watching a pro work.
Have to laugh Eric, when you said the truck is almost going to Chevy heaven, in upstate New York due to rust I just looked on the major New Zealand trading website TradeMe, there are three 2005ish Chevrolet trucks for sale all around $50,000 NZ. That's still about $33000 US, probably more than it was new over there. Us New Zealanders have a love affair with american Iron, but man o man do we pay way too much for it!
You should do a video on vehicles worth owning.
