- Ever wonder "why won't my car start after filling with gas"? In this video I show you how to replace the EVAP purge valve on a 2007-2013 GM truck or SUV.
The vehicle was showing symptoms of an extended crank, especially after filling up with gas, and a check engine light with P0442.
Sorry about the poor quality of video on this one. I didn't realize the camera was aimed too high. I tried to save it though with my awesome video editing skills!

I know you posted this 2 years ago but you are a livesaver! you quite literally went on to describe every problem I've been having and say the exact code that came up on my car. I didn't know it would be this simple of a fix
Service center wanted to charge me over $400! Bought the part for $50!!! Easy peeazy!
2004 GMC sierra replaced purge valve and 2 months later same code returned
Was yours stuck open? I have seen a lot of aftermarket purge valves repeatedly fail. AC Delco valves are definitely higher quality.
Finally a video that does what the title says. The MOST valuable tip you had for me was that clip on the inside to remove the valve! After that ez peezy. Thanks.
Thank you a million and a half Pete! Just did mine following your instruction. Works perfectly! Though YT doesn't have a "rating" system, I am giving you one. A+++++ and 5 🌟's!
I’ll take that rating!
Just got done replacing this. At first I had a hard time figuring out the white clip. It was as easy as you said. Hope this was my problem. Thanks again!!
when you replaced the evap purge solenoid, did you have to use the relearn protocol from a code reader?
Yes yes yes! I found you and answers desperately needed
I have a 2022 Blazer and yesterday the engine light came on for the third time in 18 months and the diagnostic says purge valve/pump. Any else have this problem? Even more important, anyone know how to fix it permanently? I don't have a gas cap, so it's not that it is not tightened.
My check engine light came on at 5800 mi, code P146b 2022 TB, I suspect it is the vent valve.
Ha !!
This is exactly what you had me do years ago on my wife’s trailblazer!!
Love it man you look good on camera.
You should have started the engine to hear the difference.
Thanks for the Know How Pete! Keep up the Good Work Bud!
I think you may have helped me reassure it’s my purge valve that needs replacing. As I get the check gas cap and engine light msg. Imma go grab one of those bad boys payday and put it on. Cheers 🥂
Video starts at 2:58
Very hard to tell what you were doing. It’s unfortunate every single car has different looking wires under the hood so it’s difficult to know what is what. I have a P0446 code on my 2004 Chevy Malibu with check engine light on. My bro in-law friend said it’s probably the catalyst converter because of that code… is that even possible ? I haven’t seen anyone else mention that .
Sorry about the poor camera work. There is still good info in the video so that is why I chose to still publish it. The p0446 code is caused by a problem in the evap vent valve circuit. The vent valve is near the charcoal canister near the fuel tank at the back of the car. There could be a problem with the wiring or the vent valve itself.
@@PetesGarageandperformance thank you for this beautiful explication God bless you
@@PetesGarageandperformance thank you for this value information
My car doesn't have a check engine light on but I ran a test anyway and I got this code. I don't suspect this my gas cap. I heard that if it is stuck closed that's your best scenario. I don't have any of the symptoms of it being stuck open that you mentioned. Thoughts?
Thanks you really good help
(2007 Chevy Equinox) - My issue was a substantial reduction in miles per gallon (much more City miles than Hwy miles - was getting about 170 miles per tank instead of about 260 miles per tank). CARR Chevrolet Service Department (Beaverton, OR) could not find the problem (but charged me over $400 just for looking and not finding anything). Years later, my car throws an EVAP code (P0455) and Honest 1 Auto Care (Hillsboro, OR) found that my Canister Purge Valve needed to be replaced (it was stuck OPEN). Problem solved.
The code in my olds bravada suv is p1441-replace evap solenoid. Is it found in the same spot as this video? The part itself is 40 bucks so I'd like to try to fix it myself
What year and engine do you have?
@@PetesGarageandperformance its a 2002 v6
On your engine it’s kind of difficult to get to. It’s on the driver’s side of the engine below the intake manifold. The connector is red. Just FYI, the engine is an inline 6 and not a v6 on that vehicle.
Amber, my love..i would come from new york, to install yours, for free! you..... pretty girl!
Did you figure it out? I'm getting the same code.
Would replacing it solve the hard start after filling up issue?
Most likely. Take it off and see if you can blow through it. If you can, it’s junk. It should be closed until it’s turned on.
Great job dude!!!
Very informative only to short some people will not now that are parts covering those wires and may be disappointed to do it them selfs I know it's comment sense
I have an intermittent rough idle after I fuel up until about the tank gets to about 3/4 runs smooth till next gas up. Gona replace purge valve first I guess. No codes
Typically the purge valve issue is only on that first startup after filling up.
I wish I saw your video before I paid the dealership to fix mines they charged me 450 when I could of gotten it done for less than half that
After replacing valve selenoid to my chevrolet equinox 2015 the obd reader still appear abour evap emmision high purge, how can i test it so that the check engine appear?
Remove it and see if you can blow through it. You shouldn’t be able to. Did you use an aftermarket part or a GM ACDelco one?
@@PetesGarageandperformance yes i bought it from the dealership from thier parts department. Yeah i also blow it and air cannot go through it. I tried to start the engine again after the replacement and check engine dissappear but from the obd reader it says under generic: permanent
evaporative emmision system high purge flow
I was told by a mechanic I needed the vent valve replaced. My tank keeps stopping while pumping gas. Will this help it?
That concern is usually the vent valve or the canister itself. Many times they get clogged with gravel dust and can’t properly vent the air that the incoming gas is displacing.
I changed the purge valve , canister, solenoid and I’m still not able to put gas normally. What I can do?
Make sure the lines aren’t restricted from the gas tank to the canister vent valve.
Help,I been trying to find the problem but I haven't I got a code p0446 on a chevy tahoe limited 2000 5.7L thank you.
You have a completely different setup since that’s the older Vortec engine. What code do you have?
Hi my jaguar x type have code 442, what can I do,,is it the purge value are solenoid valve,,
It could be a gas cap, vent valve, purge valve, tank seal etc. you need to have a shop smoke test it to find the leak.
Oh wow I had that message come on today and sure as shit the last guy that worked on my 2006 Malibu 2.2 he layed on top of the motor and broke the plastic tube on the purge valve assembly then just duct taped it back on without saying anything. Gas cap was fine. Now I know why that gas cap message came on!!!!
Yep. Good find.
@@PetesGarageandperformance Great video and content. Subbed!! 👊🏻
Thank you!
I don't have a code on my 2005 Tahoe, but whenever I get gas, the gas pump would click off several times. Could the vent valve be at fault? Thanks
Most likely it is the vent valve. If you drive on a gravel road the little filter on it could get clogged with gravel dust.
@@PetesGarageandperformance thank you, I will replace it right away.
@@PetesGarageandperformance I'm getting a P0440 and P1441 code. It started this after I got a fuel pump put on.
Awesome
Thx that was helpful
How to replace evap purger on a 2005 Toyota Carrolla s
Just fixed mine thank you
I’m having this exact issue of a long crank time, but no check engine light is on, so Since I have no check engine light could it still be an evap purge valve issue? I tried seeing if you had an IG account so I could message you about the issue, but couldn’t find one and can’t message anywhere on here
It’s possible. But usually if it’s a purge valve, it’ll only be a long crank after filling up with gas because it pushes the vapors into the intake manifold while you’re filling the tank. I would check for codes even though the light isn’t on and also check for fuel pressure while cranking.
What else is keeping it on... Mine won't slide off the bracket it's on! 😩
There is a metal tab on that bracket that you need to depress to get the valve to slide off.
How do u test it see if it's bad?
How to??? Should retitle to EVAP System Explaination and Repair
Thx a million!!
Thank you
I'm having a hard time putting gas in my truck will that part fix it?
Probably the vent valve or your charcoal canister is clogged. Gravel road?
@@PetesGarageandperformance do u have a video of you changing them?
@PetesGarageandperformance thank you!
Thanks Pete!
Where is it located on a 2015 yukon sle?!?
Right next to the throttle body.
The video was very informative I'm 64 years old I'm a woman would it be easy enough for me to do and is that the same way you do it on a Chevy equinox 2011
Yes they are pretty easy to do on those no matter which engine you have.
@@PetesGarageandperformance Thank you hun for putting these videos on here because I have no one to help me and I have to do these things by myself so I appreciate all the help that you can give in these videos have a blessed evening
My purge valve is constantly snapping. The long hose part that feeds into the line snaps off at the base and I have replaced it a couple times. I do not have the tab that I saw in your video is that what holds it in place so it won't snap?
That’s weird. Are you saying the bracket on the intake isn’t there?
@@PetesGarageandperformance So at 3:55 when you push down some tab to disconnect the line. My vehicle has a slot where a tab should be, but the tab is not there
I doubt the missing tab on the line would cause the nipple on the purge valve to break. But who knows. Are you using a good AC Delco purge valve or cheap parts store ones? I had terrible luck with the cheap ones.
@@PetesGarageandperformance I believe the first replacement was. The other two have been Duralast. Just not sure how to fix the issue cause everyone tells me it should not be snapping easily like that
Is your engine mount broken and pulling on the hose? The 6.2 mounts break all of the time. Powerbrake it in drive with the hood open and see if the engine jumps a lot.
99 1500 Silverado I go p0449
That code is a problem with the vent valve or wiring. It’s the valve back by the fuel tank.
Thankyou
I changed the gas cap..what do I do?
Mine is in the most impractical place! 2005 GMC Savanna
I got PO442 code 2003 Chevy Silverado 5.3l
It's your purge valve sir easy fix diy
Thanx👍
I can not see how the lines get removed
Press the gray tab down and pull the line off. The gray tab should be spring loaded and if you press on it, it should slide a little and that’s when you can pull the line off.
You didn't show removale?
Hard to see the details and would have been great to see the part for a few more seconds.
I knew I shouldn't listen to my husband we just payed $190. to change mine out on my truck.
Does anyone know where I can find mine on a 2003 gmc sonoma
4cylinder or v6?
trevon yeamen 4 cylinder will be through the right front wheel well next to the ignition coils. V6 will be on top of the intake manifold next to the distributor. But they really don’t go bad very often on those trucks. I would look at the fuel cap or the vent valve causing evap leak codes on a Sonoma/s10
I got gas leaking out of my purge valve has anyone had this happen?
It’s possible that the vent side of your evap system is clogged and when you fill up with gas it could fill up the charcoal canister with gas. Or it was topped off too much with fuel when filling it up, which then filled the canister with liquid fuel.
I would remove the charcoal canister and see if it’s full of fuel. Also you need to make sure the vent valve is working properly.
@@PetesGarageandperformance Thank you I figured that that is what happened.i normally keep pumping after it stops at the pump.so yeah I f'd up.I have 2 Tahoe's an this just happen on my Hummer H2,never had this problem with my Tahoe's.i guess I should have figured something was up cause when I put gas in the tank it makes a gurgling sound an my other trucks don't.Thank your sir,I'ma just replace the whole system for a piece of mind 👍
Put up a PayPal tip jar bud and lmk when it's up thanks!
Can't see anything too dark bro
Super super easy, even a girl can do it :) Actually I do most of the mechanic work on my own truck...don't know how? Watch youtube :D
ok. now head to the kitchen
Help
What is your question?
Dude you can't see a dame thing you were doing please if yur going to post a video to help people make shur they can see what your doing.. Because I might as read a book because this video didn't do anything but hear you seam good job they're bud
Yeah sorry about that. I didn’t realize that the camera I had mounted to my head wasn’t aimed quite right. But the info was probably helpful to some, so I posted it anyways. Sorry.
GOOD info but his camera work is extremely bad, oh well!
Sorry. I had the gopro mounted to a head strap and didn’t realize that it wasn’t aimed correctly. But I put it out there anyways because it might help people.
nice explanation , bad camera angles
Yeah sorry about that. I figured it was better to have the info out there so I put the video out despite the crappy angles.
@@PetesGarageandperformance LOL! , It still helped me tho , Thanks !
DIDN'T SHOW ME HOW TO REMOVE THE FUEL LINES OR THE VALVE
For someone who know i see this code atleast 5 times a day at work :/ its always a fuel cap sale drive it 30 miles if that dont fix it go to a shop worh good tool to test the other 3 choices. 😂😂 i might even get a lucas sale as well lol
Correct. Many times it’s a gas cap. But not always.
@@PetesGarageandperformance thats what I just said? I have to explain to customers the trouble code says "System" Leak Detected. It could be anything like a vacuum hose or Leak detection pump so now i just pull up this video and they can fugure it out their self.
You said “it’s always”
Terrible camera work. But thanks anyway.
Just show us how and stop all the unnecessary chatter.
Hold you camera so we can see what you’re doing! Horrible videoing!
