Gotta love a repair that requires no parts, just common sense and good judgement. Outstanding video, Glen.
Thanks, being that it's my car I can appreciate a low cost fix, even if it's long term temporary repair, I'm okay with it. ;-)
Thanks for making the video. A lot of good help tips to fixing the Vent Control Valve. My wife's Maxima just happened to have 104,000 miles and codes are starting to come up. Read the codes with the Autel scan tool.
I got i35 infiniti 2003 with p1446 code closed at wrong time idk what it means but my car jerks is only issue i have with car other dan that starts right up
Love a $0 cost fix!! Nice work Glen!!
Thanks man, my wallet likes it too. Hopefully it will be ok for a while, so far so good. Thanks for your comment!
Thanks very much for taking the time to make this video, especially with the mirror!!
Thanks for the positive comment Neil.
Great video! No parts needed...a Lil panther piss and persistence does the trick! Thumbs up!
Had those pliers for awhile. Think mine are HF. great job Glen! And yes when it is your own vehicle, why not experiment!
Fixed on the cheap, for now. Thanks Mike.
I haven't tried this, but a racer has been using WD-40 in his carburetor after every race so that all of his rubber stays good. WD-40 is an "oil" which actually protects your rubber. Counter-intuitive in comparison to some oils. When I saw this I had to bookmark it a month ago. I'm so glad I had the chance to come back and see it today. :)
Bro so of code p0440 is the vent valve solenoid problem???
You weren't kidding about those bolts lol as long as it seals and opens it looks like your good to go, thanks for sharing Glen, good work 👍
It's been good so far.
Great video glad i came across it..hopefully this helps my situation..2001 pathfinder p0455 and p1448..im definitely try this tomorrow
Good luck. Let us know what you find out.
@@ozzstars_cars I definitely will thanks
Very well done, Glen.
Thanks, good to see you stop by. Hope all is well man!
Nice video Glen.Those bolts can be a real pain when they snap.
Nature of the beast. Thanks Jim
Nice video. I get these 2 codes usually on my 01 sentra. I replaced the gas cap but the 440 is more common than the 1448. It’s crazy. Bought a new purge valve along w some lines. Hopefully it will help
Friend, where is the location of purge valve in 2006 ford fusion SEL 2.3 L 4cyl. Can you help me out
Adapter and overcome Glen. Nice job on the work around
And on to the next fun project. Thanks Lloyd
You are the best engineer
I am not but thanks.
Ivan would be proud, fix it with a spray. You did the right thing. Who wants to struggle with stubborn bolts.
Ivan was my mentor for this one since I don't mind experimenting on my own wheels. 😁😁😁 Find a Vette yet?
Good job Glen !
Thanks Norman, it's a band aid to stop the service engine light blues. ;-)
Wow, Great vid, I m a car guy from the late 60s.. "sensors" UGH !! What a great straightforward, easy to absorb how to. P.S. I use BP Blaster ..it travels up threads, and gets where other formulations can't. Never had any issues with rubber gaskets.. Thank You..
P.S. If possible re apply PB Blaster give it a little time to soak in. An old mech told me to try to tighten the bolt ever so slightly..... NOT like you really want to tighten it . ..( I'd say 1/10th or so of a CM) then reverse it.... counterclockwise to loosten. If the area is dry then reapply PB Blaster, it will creep whereever there are matching threads.. You probably won't get away with extracting it that easy.. Just apply more PB Blaster.. then work the bolt again clockwise to tighten it 1/10 of a CM etc then again counterclockwise till you can fully back it out. Be patient. That has worked for me more than anything else. Smacking the head of the bolt to shock the threads works ok re heavy metal to metal etc..engine block. I use the dark air hammer sockets with a hammer to deliver the strike. So not to damage the head of the bolt. BUT in the case where plastic is concerned.. This could damage the plastic charcoal canister area right where the female threads are embedded.. Now I'm the new OLD guy. LOL LOL..
Good Luck.. BTW back in the day we complained about the new emissions device the PVC valve. We never knew we had it so good..
PB is my favorite flavor. Only about 9% of us in the population are car people. The rest just leave their shopping carts out in the middle of the parking lot! Thanks for your comment.
Good video Ozz
Thanks!
Another job well done Glen . I have them pliers , came in a set of three different sizes , love them for taking off hoses and tough electrical connectors too .
Yes the three set hose pliers deal is what I have also. They can be used for more than just hoses. I'm sure you can figure that one out Steve. haha ;-)
came in a set of three or you got 3 sets hahahahahaha
@@BackCountryWrenching Smart ass 😅😅
@@BackCountryWrenching yes 3 sets. I do tons of nipple twisting/ pinching and they wont warranty the worn out pliers. 😂
Great job Glen and I would have done the same thing. Should be good for 100k miles. 😀👍
I have a feeling this 'fix' will work for a while. Probably better than replacing the valve with a Dorman unit. lol
Good video Glen
Thanks man, appreciate you checking it out.
dust gets in there and sticks the valve... if it came apart easily something would be wrong! hmmm I thought the vent valve is normally open but its a Nissan I seen spider webs in the air baffle hose also good work glenn
Thanks man, the valve seems to be moving now. Time will tell. Take care man.
I have found that placing the socket on the bolt head and smacking it with a hammer a couple times can help loosen inside to break loose. Also if you're brave the heat gun
I'm all about using the "heat wrench" when it's all steel. Plastic melts and then it's toast. In this case 1 1/2 years later the vent valve is still working perfectly after using some oil.
@@ozzstars_cars had to edit that comment. Yes sir anytime I can get heat to either the part or the bolt sometimes the expansion it's enough to keep from breaking it.
I got a 05 nissam sentra with 400k miles on original motor amd trans and it was sticking closed and not letting me pump gas fast then i drove ot more afte i dodnt drive it for almost a yr and it started letting me pump gas but now i think its stucl open and its showing large evap leak so i think that valve is all it is thats kicking the codes on.
What is rust? Mechanic in a can never fails. Nice job
😁
I think there was a mistake about the valve position when power is applied. The valve is normally open. The valve closes when you apply power. I am doing one right now. If it was normally closed all the time, it might be difficult to pump gas with car turned off because the vapor cannot escape when filling. Anyways good job!!
Yes most but not all vent valves are normally open and then closed when power is applied. The valve in this video is still working good. 👍
after6tuning I had the same problem with my 2007 versa, I couldn’t understand why I was having problems filling the tank even with the valve closed. That would explain it👍. Cleaned out the valve, lots of dirt.
I always get a long rubber tube, clean it off, and use my mouth to check for flow and vacuum. Vacuum tools always seem to get something on their seals and they quit. My mouth will keep working as long as I'm breathing, lol.
haha Good to know man!
2010 Maxima- service engine soon won't come off - changed Gas cap and purge valve under the hood - still issue - scanner states 2 red , so won't be able to pass inspection- could it be the vent valve under the gas tank ? Thank you
You didn't mention what trouble codes the car has. Need more info.
@@ozzstars_cars originally P0456, evap small leak
I cannot find the location in my 2000 Nissan Frontier. Any idea where it is located? Thank you
Did you look at the top of the vapor canister?
I got p0440 on a 2000 Nissan Altima so would it be a sensor ?? I don’t think there a cracked hose or nothing
Most likely. Test the sensor to confirm.
Right after I replaced the valve (I had p0440 and p1448) the codes cleared, but then I got a p0446 code...any ideas on what to do next? I have a 1998 Nissan Frontier...thank you
What brand of valve did you use? Did you test the power and ground at the valve for proper voltage?
@@ozzstars_cars I can’t recall the brand, but it’s not uncommon for parts to be faulty out of the box, right? Also, the shop I took it to said he bench tested the valve and the plug for power...I’m just not sure. I picked up an EVAP canister at a “you pull” yard and was thinking of getting another valve to put on the canister and replacing my old one. Maybe I should check for power when I take off the old canister? Honestly, this started with an o2 code, then an intake thermostat code, then vent valve and now this. Literally one after another. Yet, the truck runs fine. It’s all for an inspection lol
Bought yourself a little bit more time... I've got a couple cars with similar (repair) issues that I will eventually have to deal with.
Working on my own junk is the last thing I want to do. haha
I'll get to it next weekend... is what I keep telling myself. LOL
LOL isn't that the truth!
I had the same problem with those rusted 10mm I accidentally cracked the canister $220 🤕
Ouch....that's pricey.
It's always just one bolt that gives you a headache! I don't know why I hate Evap codes.
And it's usually the last bolt that needs to come out to get the job done! Take care.
You don't know why? ... I'm done with hating them. They're usually easy money having done a lot of them now. :) :D
The pain a few stainless bolts could save. Nice fix though.
Thank you sir.
My wife 99 altima has the same code. Will this cause the car to be very hesitant off and on on take off?
I don't believe a defective vent valve would cause a drivability problem, the purge valve on the engine side certainly would.
@@ozzstars_cars the same code u had is the only code my wife's car has.
@@michaelandrisko748 unfortunately a code to a particular sensor does not mean that is the issue. Diagnostics is the key to finding the problem. Did she overfill the gas tank? Pumping in excess fuel after the pump clicked off? This would saturate the carbon canister with raw hydrocarbons (gasoline).
@@ozzstars_cars yes I know how to diagnose a car. I just figured I'd ask u if there are any running issue symptoms of this code. We just got the car last week. It has older gas in it. Sat for 5 months. I've added seafoam to the fuel. Changed plugs, wires, cap and rotor and air filter. Next I'm changing fuel filter and I guess checking fuel pressure
Nice. Nothing like fixing it for free.
True!
Mechanic in a can!😜

Been having issue with p0448
EVAP diagnostics time. Vent valve testing.
@@ozzstars_cars i believe I did that I have a 06 Sentra I had that code for 2 years last year I took it too mechanic and he change the control vent control valve 6 months after the code re appears
Are you supposed to hear a click when you turn on the key?
You mean the fuel pump running?
@@ozzstars_cars the clicking noise that you made that's what I mean from the canister
@@ozzstars_cars I want to test it to make sure it's working. Will it click on its own when I turn the key and while I hear it?
@@aaronpodgorski1617 no it won't. Scan tool or manually with 12 volts.
By replacing the vent valve that could be the cause of my p0440 code
Test first. Repair what is broken.
So whats of problem on code p0440 sir ???
The PCM has detected a leak in the EVAP system.
Any way to turn off all those GM alarms 🚨 seatbelt , hey in, door open ?
Most anything can be accomplished with time and money. lol
Was the car jerkin or not able to pass 30mph
No, ran fine.
I have infiniti i35 2003 p1446 code for sum reason car starts fine as instant sounds quite but for sum reason it jerks or like chokes idk how explain it
@@Sinister_187
I have same problem 2004 Infiniti i35 have a couple code but when the car was jerking from accretion from a stand still I replaced my air filter and it doesn’t jerk anymore code still remains though 😅
Canister Vent Valve was my issue
Help me out with p01447
Nice fix,Ivan would be proud! And enjoy your nipple pinchers😉😂😂😂
I'm not kidding Mike that is the truth. When I busted the WD40 and silicone spray out Ivan's voice was in my head and well....... haha!
@@ozzstars_cars 🤣🤣🤣🤣
Nissan's melt like butter in the states when they use salt. The bolts are made out of inferior metal. I used replacement cheap 10 mm bolt from Amazon and they held up better than the originals. No Wonder Nissan is slowly going out of business
Nissan quality has gone down hill, this is a 22 year old car. The new Nissan's won't last that long.
There is one in every crowd/comment section lol. it said vehicle MAKE not MARKET lol just bustin your stones
