EVAP P0456 Diag & Repair: Nissan Rogue - Part 1
HTML-код
- Опубликовано: 13 окт 2024
- This 2010 Nissan Rogue has been having an intermittent leak in the EVAP system. Let's see if we can pinpoint the leak, and even fix the problem without going to the dealer for parts!
Enjoy!
Ivan
At time interval 7:05 the vent solenoid is commanded ON so the valve is closed. Ivan then uses lung capacity to determine if the valve does seal. This is a "quick and dirty" test but the problem is that you are apply far more pressure to the valve than originally designed. Typically the evaporative system valve devices are intended to hold about 1 - 2 inches of vacuum. That equates to about 0.5 - 1.0 psi negative pressure. If more positive pressure builds up in the system, it is designed to open and prevent an over pressure condition in the fuel tank.
A better test would be to seal the inlet side of the valve port which connects to the tank. Attach a hand held vacuum gauge and apply about 1 - 2 inches of vacuum. Command the purge solenoid ON to close the valve. Watch the vacuum gauge and if it holds for several minutes then it is good. In a sense you are doing a valve leak down test and that is what the ECM (electronic control module) is doing to verify the integrity and proper operation of the valve.
This is a good point Ivan. You put some real air pressure (lung power) on that vent solenoid
How many psi can my lungs produce?
A young, healthy, non smoker- blow into a gauge and find out. Using an aneroid barometer, equipped with a mouth inflation tube, maybe 2-3 inches on the scale where sea level atmospheric pressure is about 30 inches of mercury. I think a top figure for the average person would be about 1.5 psi.
1.5psi seems to be a good number. Hey! That's what EVAP smoke machines are rated at! So the human blow test is actually perfect for EVAP components. That's cool!
This guy is a wannabe, A DIY not a master class (A) tech like me.
"I don't want to spend any money on this thing"- classic.
My daughters cap was loose on her car. Tightened and cleared codes. Hoping that does it. If not, rock auto is my friend. Thanks for video. Seems easy enough to tackle myself.
The rust is unbelievable! ! I do not know how you east coast guys do it lol 👏👍
Very similiar to the toyota VSV valves. The toyota vsv's will create a ridge and actually get crusty and stuck. Moisture/water will make the piston/cyl crusty in cooler months. After replacing a few I now Fluid Film the internals on new ones and I've had no failures on the new ones yet.
I learn something new from your almost every video you produce somehow or another just by seeing your thought process. Thank you.
I've torn quite a few of them apart, the failure are mostly due to the plunger dragging in the hole, from the coil melting the plastic, or rust depending on design. of course sometimes the seal is worn/dirty and if they don't seal 100% you get the leak codes set, it will be back on for sure :)
You'll enjoy Part 2 :)
It's definitely worth a shot. I can't help but feel incredibly wasteful when an entire component needs to be chucked because of one issue that can often be solved with less than a few bucks in parts.
If you can get some more time out of the old one you'll be ahead. I like trying to fix things on the cheap so I can but more tools. By the way, replacing the fuel pump on my 98 Chevy truck fixed the fuel pressure drop. I'll have a video late this week (if i get my computer back from the shop). Thanks for the support.
Nice!
Part 2 is as follows---Mrs Ivan blows her top-----Ivan has no dinner for weekend------he goes to the Nissan dealer and buys the valve-------The birds resume their mornin song----and peace reigns once more !
HAHAH very good guess. I do manage to save the situation :)
Ivan I agree WD40 is an magic WaterDisplacing fluid, but it does not last long enough, so I use a silicon/teflonspray afterwards and that will last forever. Nice music by the way, regards.
Thanks very much Bud! Worked for me just cleaning out the Vent Control Solenoid with water and WD40!
Son, you just washed out a vent solenoid! haha Nice work Ivan. Lubrication is a good thing. Might just fix it for good once it cycles a few hundred times. Thanks!
These plastic EVAP components are often revived by a soak in warm soapy water and use of a long bristle thin paint brush to gentle coax the dirt out from the internals. After drying I tend use silicon spray as a lubricant and a thin smear of silicon grease on the mating surfaces of gas tight seals; cotton ear buds are great at getting into difficult to reach places. Due to age or after minor collisions the carbon dust in the EVAP canister can come loose and effect the purge valve performance, but the repair is just the same as the vent valve.
Those vent valves fail very often I work for Nissan. also your wife's truck may have a TSB that applies to it for the CVT transmission. Just check the CVT a and CVT b PID's in the transmission module. They should be 0. If not than there may be a CVT failure in your future.. The TSB is to replace either the trans or The Valve body and add an external grill mounted cooler. This may also be covered under warranty. The warranty on a lot of those I think may have been extended to 120k mi..
If the CVT count is high let me know I'll see if I can get you a copy of the bulletin.
Well at 182k miles she's got her money's worth out of this one! I always check the CVT fluid quality life with the scanner. It shows about 2/3 used...should I change it soon? Still looks clean on the dipstick.
motoYam82 you can change it, sure won't hurt it. If you do change it use Nissan ns2 and set the fluid level using PID ATF temp count @ 160. It takes some time to get it to 160. I think the PID is "atf temp count" or "fluid temp count". Just make sure it's at 160 or very close to it when you set the fluid level on the dip stick this must be done right its very sensitive.. But the main thing to keep an eye on is the CVT A and CVT B PID's.. Those are over temperature indicators.
At 182k miles shes doing good.
I believe the Nissan recommended "CVT deterioration" number for fluid replacement is 200000 in the scan data not miles. But i usually just recommend it every 60k miles. Be sure to reset it when your done.
200000? Wow! Right now it's only at 65000 and I was going to let it get to 100000, which at this rate would be 600k miles lmao
Yeah.. Nissans recommended interval is nuts. I can't say I have seen any failures due to fluid neglect. So maybe it's plausible but My OCD won't allow me to run fluid that long.
That "part 2 is coming" indicates it didn't work LOL.
When I do stuff on my truck I feel so free to do whatever I want and do as many Mickey Mouses as I can. But I don't touch my wife's car, not even to change a tire, one tiny mistake and I'll have her bullying me for weeks. LOL!!!!!
I used to change those all the time when I worked at the Nissan dealer. They have a high failure rate. That is the updated style though so not as bad. The old style had the solenoid in a plastic case and they would rust internally and swell up and crack LOL.
No doubt. But I'll do everything humanly possible to restore an old part to avoid buying a new one haha
Ivan maaaan I love your work.
Listen I have a suggestion for you to change direction a bit in shooting your great vids. Which will definitely boost your channel big time forward.
There's something extremely important about fixing cars that nobody on RUclips has ever come across at least as professional as u.
Have u ever thought of sharing your knowledge with your fans in a different way. ??
Don't get me wrong here!!
Your videos are awesomely awesome no doubts.
However, I noticed that you have thorough knowledge in wiring diagrams.
But I tell you the truth, at least 90% of us as technicians don't know most of the symbols and arrows on those diagrams and what they mean. !!
Thus, i strongly suggest that you start planning to shoot a 2-series special just on wiring diagrams.
With plenty of examples of course, specially on SUV Ford, GM, and Japanese Lexus.
Believe me such tutorial videos sky rocket views almost instantly.
Just look after what information people need the most.
Maaan I really love your work approach and thinking process. So I thought I should share this with u.
Maaaan, I never missed any of your publications.
Keep up the high spirit. We just love u
But hey, don't ever cook anything again. 🤣
Wiring diagrams huh...every manufacturer has a different style. Not quite sure what you would want me to explain about them...like the symbols drawn inside modules?
"It's my wifes car I can do whatever I want" Famous last words, until there is a problem. I wish I had a camera rolling the last time that situation bit me in the ass lol
I agree. Ivan MUST have a comfy corner in the garage next to his wood stove. He might have to spend some time sleeping there!
hey Ivan. Another great video. I have a question about your test light. Is it a 194 bulb and pigtail? what is the amperage on it. can you use noid lights as test lights?
It's a 300mA bulb, single filament, from a 1970s Kawasaki motorcycle I believe lol
Thanks great video learn something new today
Can I ask what kind of diagnostic device you used on this video?
Off topic question Ivan. Your Rogue with 185,000 miles, does it still have original CVT and engine? My buddy bought a 2012 2.5L with CVT and only 37k a couple of months ago and the CVT whines on 3,000 RPM's and up when passing on highway or on an steep incline. The fluid level, condition and smell seams good. Dealership said this is normal for the Whine, but my 2011 Altima with same engine and CVT at 60k is quiet as can be. No drivability issues or codes. With all the horror stories about CVT's on the Web I fear it could be early signs of failure and I want to make sure it's covered under the 2 years warranty we bought before it expires. Thanks for the awesome video and tell Eric O. Hello! Waiting for part two! :)
Oh yeah her Rogue sounds like a freaking chainsaw if you give it the beans, but it's been that way for a long time and isn't getting any worse as far as I can tell. Drives great and averages 28mpg summer/25mpg winter :)
Awesome thanks Ivan. I wonder if it's because the rogue doesn't have a transmission cooler lines going through the radiator causing it to get hotter? My Altima has cooler lines that have a bypass through the radiator to help cool the fluid. So you have original engine and tranny in your still? Thanks!!
Yeah all original drivetrain. I think the CVT is cooled by engine coolant if I'm not mistaken...should be a more effective way than just an oil cooler.
My Rogue has whined since the day I got him, but it's not gotten one bit worse since. And he always fusses up any incline and 'ticks' when it's really, really cold outside until he warms up, but I think that's just how Rogues are! I bet your friend will really like his :)
Hey Ivan, One time I tried that approach on a '98 accord which has a similar setup, then at the end realized that it was leaking on the housing cover not the pintle.
I have a 2011 nissan rogue with evap codes. Thank you for making this vid. 😊
same procdess as a iacv (idle air control valve), thanks for the video
great video bud don't lie u only worked on it cause the snow storm how did u fair I got 30 inches up here in upstate ny👍
Less than a foot here but the drifts are ridiculous!
Order your body panel clips off amazon, you can get a kit that has most every clip you will run across for 15-20$ that comes with the necessary tools to use with the body push pins.
that was a pretty simple fix. hope it works, if not then you can just replace that solenoid. nothing too hard.
If at first you don't succeeed...throw some parts at it? Not at PHAD!
Hey man what are you using for a test tool, I have a 2009 rogue and have the same code P0448 but have no way of testing the circuit!
Hahahaha "It's my wife's car, I can do whatever I want."
On a more serious note, I effin hate EVAP codes. I just finished up an Expedition that refused to pass the in-bay test even tho I had fixed it. Very frustrating trying to verify a fix like that. Dern Ferds!
hey man i enjoy your videos. can you show us how to remove the pass side air vent the circle one. mine disconnected so when i turn it it stays shut from the inside. rouge 2008. please
Being a Ukrainian i thought i was cheap , but Ivan my hat is off to you LOL I do have some Ukranian customers ... they would agree xD
Hey bud, i replaced the selinoid like you were showing but now it is leaking out of the frame? There is a hose from the canister that go into the frame, smoke comes out of the hole in the frame rail, any idea, its a 2015 rogue
Solenoid has to be commanded CLOSED during the smoke check :)
@@PineHollowAutoDiagnostics thanks
Children of the shoemaker (or this case, wife) go without shoes ;)
You can buy a bag of 100 "push rivets" on eBay of a couple of buck. Get 3 or 4 sizes. You might want some "Christmas tree" plugs while you are shopping.
theoldwizard998 Yeah and the removal pliers to minimize damage at Harbor Freight m.harborfreight.com/push-pin-pliers-67400.html
What's the name of the part he's banging on at 5:26? It's like a dirt shield for the evaporator canister? I went to remove the solenoid and that part was so rusted that it literally fell off. Trying to find the name to buy it and replace it.
typical mechanic,we all do that fix everyone's vehicle but our own i fixed how many and my wifes check engine light is still on lol😄
Hello there. Do you happen to know how 2012 nissan rogue transmission cooler is connected? My comes from cooler into engine,not to a radiator. I wanted to flush the system but its not possible. Please let me know if you happen to have the answer . Thank you
It certainly looks and sounds better, but how would it get mud in a semi sealed system?
Through the vent hose...apparently filter isn't good enough!
Thanks
Дякую, допоміг 🇺🇦
Thanks, helped 🇺🇲😉
Thank you for the help
Has this car been reliable for you ? How many miles ?? Brake Cleaner and WD 40 the the fix all tools ! keep up the great Video's :)
at the beginning 148k i think
SuperJoes70 182K miles!
Most reliable vehicle I have serviced long-term. It's nice to have at least one of those in the fleet haha
Anyone knows what voltage is applied on the Evap solenoid by the computer? Is it 12 volts or lower like say 5 volts. Would like to test the Evap solenoid off the vehicle.
HAPPY WIFE.. HAPPY LIFE...
Ivan, which headlamp is that? Do you like it?
Foxelli rechargeable. It's great, but battery life is kind of short and takes a while to recharge. Definitely buy two or three to cycle them out!
Ive changed mine and after about 2 weeks im getting the same code! does that mean my wiring could be screwed?
What has you been using the autel instead of the verus?
Great video
Thank you ❤
Had the same problem with my ex-wife's vent valve, cleaned it with gas and sent her and my ex-mother in law on their way......to heaven!!!
lol
This works on a small amount of vacuum drawing out- not high air pressure blowing in.
vacuum on one side = pressure on the other ;)
Yes- the barometric pressure of around 12 psi (at sea level) is holding your guts in, and pushing on everything.
thats how it normally works ivan
Народ! Если у вас горит ошибка U1002 то проблема в этом клапане вентиляции абсорбера (это который свободно открытый) находится на самом абсорбере.
Нашел эту инфу на американском сайте, и клапан оказался не рабочий, всегда открытый!
И когда мотор хочет продуть абсорбер клапан не закрывается и всасывает лишний воздух с атмосферы.
Been having p0448 for a year with 06 Sentra mechanic change vent control valve the next day code re appy
A cool vid for sure Thanks for that.
Best of luck friend.
Did your Nissan CVT transmission actually last over 182,000 miles?
Luckily my 2009 Nissan rogue hit 200,000 last week and transmission still going so far
@@joshuamcmichael4121 That's great to hear. Thanks for sharing. I have a 2017 and I canceled my $2500 dollar extended warranty because I thought the tranny would probably quit after the warranty expired at 100K miles anyway. Anything else I could probably pay for out of pocket.
@@joshuamcmichael4121 cvt fluid changes? how often? is your original water pump and radiator still working? do u flush rad fluid often?
you should build an underbody car wash at your house. that's a lotta dirt under there..
do diesel cars have this aswell ?
hi there Ivan
I'm having same code on a 2017 Nissan Rogue.Is that the issue??
"my favorite magic fluid" 😂😂
Did it come back on??
Id be like pressure washing that first. lol those plastic pieces suck. I have boxes of plastic plugs from trying to find the right sizes.
its a $16 part on Amazon, ??
Ok mine came on 5400 miles is that possible?
What reader are you using? Apologize if this is a dumb question
I only have 42,000 miles and just got this lol
Scanned my 2015 frontier had 1 week, for kicks! title says Datsun scan tool says General Motors /Isuzu, truck say Nissan! make up my mind?
What no brake clean , oh wait that's ur buddy up north there
Worst thing that can happened with your wife's car! is that you can end up sleeping on sofa for a while!
Las las 30 second so funny 🤣 😆 😄 get new part buddy 🤣 or new 🚗
did not see it was up to 182000. doing good then
must have been a Snow Day ..!!
who has time to work on their own stuff .. ??
first one
Yeah 6:30 aint going to win you many wifey points.
Oh , much worse than that, could get the wrath of Eddie the grouch on him.
LMAO oh man he definitely keeps us in check in the Quality department!
.
?
Dead pixel, Black hole, End of the world. No way, he is telling you to probe right there.
OMG, Dude you just lazy or is cause its your wife car, You have it off already FREAKN CHANGE it........OH and Happy Mothers Day.......
ewwww she bought a nissan
I think she made a very smart decision!
lol i hate working on nissans...
Not good enough
