On the 2002-2006 Avalanche, this solenoid was inserted directly from above into the intake manifold vertically at one end and a hose snapped onto the other end. It was easy to repair. On the 2007 Avalanche, this solenoid is mounted on the side of the engine in a less serviceable location and has a second hose running to it from the intake manifold. So now this solenoid is in a less convenient location and there is one additional connection. As usual, "improved" serviceability and "increased" reliability.

Thank you for your clear voice and detail as well good visual. I have 2005 GMC Yukon Denali got latter code 0496 one day after filling gas tank. Thought it might be gas cap. Tightened, cleared code and day later back to code. Of course, I said WTF. Searched online code and then asked my mechanic if through experience could it be the purge solenoid valve in engine which I would do myself. Was hoping he would just attach his more detailed obd reader. Instead, he suggested smoke test. I rather go simple 1st instead of expense. I appreciate you identifying the difference in the codes. I will test purge valve myself by blowing thru it and see if air flows which would tell me its stuck open. For what its worth also saw a video where you can disconnect hose and electrical to valve, start engine, wet your finger and place finger against opening in valve and if there is suction than its a faulty valve. Anyway thanks again for your video identifying code. Cheers Michael

Thanks for posting this video, I could not figure out how to get the clip off. After watching this, it was a 5 minute repair. Feeling good!

Very helpful about the remote start not working when check engine light is on. My remote start has not been working for months. Which, is about the same amount of time I have been staring lazily at this check engine light. I never associated the two and simply figured my remote start died or was fried or whatever. Now that I have replaced the solenoid, and rest the code, I’m excited to test me remote start again as I always enjoyed that function

This video was very helpful. Feeling accomplished after replacing it myself. Thank you!

Same part I need to replace. Glad to see step by step and what to do. Big ups ☝🏽

Thanks for the video. It's basically in the same spot on my saturn vue and looks almost exactly the same. The video really helped out. The repair shop wanted $120 for them to fix this. I can fix it now for only $25 for the part. So thanks

My Tahoe had the check engine light on and I did this and it didn’t go away so I was going to go back to auto zone to see why and half way there my engine light disappeared all I had to do was to drive the truck for a little and it went away.

So that's how it releases, you're a lifesaver thanks bud

This video was spot on with my 07 Silverado. Very appreciative. Thank you so much !

Very helpful. I have a 1989 camaro and had to replace the charcoal purge canistor, evap valve and evap solenoid. Unfortunately they do not make a replacement for that year 89-92. Its an odd combo parts. It is a combo solenoid and cannistor set. The seperat tank line valve is still made. As is the vent valve next to the actual fuel tank. I used te newer model 1993 camaro evap solenoid (same part that was used in this video) and a basic round GM charcoal cannistor with the tank, intake and air ports on it. This video confirmed that the grey end goes to the intake/tbi and the black end comes from the charcoal cannistor via an additional short hose section i had to supply to connect the cannistor port to the solenoid port(back end) and grey end to the intake line.

Thanks for the video! Took about 5 mins to swap out after watching it. Would have taken MUCH longer without it.

The purge solenoid is the one up front. The vent solenoid is the back one by the canister. I could be wrong I'm not a technician. But good job figuring your problem out. Very informative.

Just wanted to say did an excellent job on explaining on how to take out purge valve and install new one I had seems like exact same problem. I did break one of the clips but only cause it’s like 20° out here in Massachusetts. You couldn’t have explained it or showed it any better thank you

Thank you for this video! Helped me out very much! Could not figure out how to release the horse shoe clamp part out .. almost broke it until you mentioned you just push to release..

Thank you for a video that's right to the point and clear to follow...

Great detail on how to from beginning to end of video! Thanks

Good job!! I've replaced so many of these, I know the part number by heart

It's one of the last sensors to get read by the OBD II. Took me about 5 days of driving to finally get it to set. I had the same problem with my 06 silverado 5.3.

Very helpful in explaining the clips, 5 minute video, 5 minute job. Thank you!

Awesome video I have a 2007 chevy avalanche so this was extremely helpful I'm putting this exact thing in my truck

perfect man ...I couldn't figure out to disconnect it ….thx so much

Good job sir! Thanks for the assistance.

Awesome video thank you so much this was the problem on my 08 Avalanche

Thanks I really appreciate it, I learned a lot and may can try it myself

Thanks you made it so easy mines was right on top of the engine on my 5.3 motor

If the part was $25, they would have added $10 for the part. And $80 for the labor. $115+ tax.

Thx mine jus went out yesterday. 3/23/19. I'm going to replace it with a action Delco instead. Thx for the video this will help in the next day or two..... gave a thumbs up.

This helped me a lot . I have the same issue with my Tahoe

Thanks Bill this video really helped to save money.

Great Video, Thanks Bill....Very Helpful

thank you youtube I fixed mine for only 60 bucks for the part but the old one was shot on my chevy traverse

Look at all that room under the hood...nice!

I just changed this in my 07 Colorado. Had to take the front drivers side tire off and then plastic firewall and it was up against the engine block. I was getting a p0446 error code. Looks like the same part. Much harder to get to on the Colorado.

Thank you for the video !! That help me a lot

Thanks for your great help, God bless you

Defenely your video is helpful really appreciate and people like you who's make video to share with others I really appreciate

purge solenoid is in the front, vent valve is in the back. should clean the filter when replacing the vent valve

Looks exactly like the one on my 2006 Malibu 2.2.

2:13 how do I disconnect that type of end on the hose? I don’t know where to push or pull.

Changing mine today.

Was symptoms were you getting to have to change that part

I replaced mine forv18 bucks. I hought the cheap chinese part and it worked for a while and then failed.....but then it started working again.. The oem part was 51 bucks. I would suggest getting the oem part.

I changed my purge solenoid but my scan tool still saying it’s not working after I cleared it any advice

I like your scan tool thanks for your video

How long before check engine light went off ???

Big thanx your a great teacher

Reset codes after repairs.

Good video.. what is the part number you used on the back?

Thanks for the video.....

Thanks! Appreciate the video

I changed mine on my 2012 camaro, will I have to get the code cleared or will the light cut of on it's own?

great video! Thank you very much!

Good work brother!!

Great Job. Thanks!

Please help where is located in a 2002 Chevy Camaro can’t find any videos for it

Looks easier than the colorado. Exact same part

had to subscribe we have the same car thank you so much 🙏

Besides a scanner or batterys cables taken off. How do u turn off light on dash board. Lmk thx

I have same 07 avalanche, no lights on dash, but when I turn key, the starter works, but spins for like 6 to 8 seconds before firing. Could this be the issue with mine?

real helpful thanks.

How does it have to be pushed in

What was the symptoms for that part

mine was missing clip but i replaced it by sliding new rubber hose over the thin plastic purge lines. erased code.po446. so far im good. car runs better now.

I had code p0449 and I changed the one in the back erased the code never came back but truck idle little rough The needle bounces up and down do you thing if I change the purge valve will fix it

I have the same problems on my 2006 Chevy Silverado and my 2010 sierra I went to a mechanic he trying to charge me $600 to fix it and I came to KZfaq and learn how to fix it my self and save me $1200 on both lmao 😜🤪

Thank you!

whats the name of the white clip and do you have a part number on it..thanks

Is there a risk of gas leaking while changing the valve?

I wish my car was that easy have a cavalier bugger is in the back of the engine below cold air manifold can't get to it from below either due to sub frame blargh so I will be having fun at some point

How do I remove the white clip

Great Video, i have the same truck color & all. Just curious, did you find out how to service the TPMS, i saw the message. Thnx again.

We're u getting vapor smells in the cabin of the car?

Does anyone know the part number for this particular error code.i need to buy one . I can't find part number.thanks

After changing , does something need to be reset?

Always use OEM parts! No acceptions!

Not these days it's minimum $44 and up. Everything's crazy prices now with parts and food ECT and the parts are so cheaply made it don't last all. I went through three Purge valves in two years China's effing with us like usual. Pissing us off with cheaply-made crap parts.

My avalanche has po449 and po455 so both part are bad.

we have a 2007 Tahoe - I hate the tire pressure deal!!!! not a cheap fix (expect $50-$120/tire) I have replaced that purge valve on the engine 2 times both from Autozone...not sure if those duralast models are worth anything great video though

I replaced this part after getting a check engine light code to replace this on my 2004 Silverado and the code still comes up after 2 weeks of driving on the new part. Anyone have any ideas?

Great video

What was the symptoms

You didn’t exactly showed how to remove the piece.

My light hasnt come on

thanks dude

It could be as simple as changing the gas cap.

Just replaced mine and service engine light will not go off! Do I have to reset it manually?

What about in a Chevy Camaro 2000, I can’t seem to find it lol

Nice

At a dealership they were gonna charge me 230 dollars for this repair that cost me 30 bucks

ac delco is gm 🏁🏁👍

I save tons of money by switching to Do it yourself videos😂😂 thanks for the video it helped me figuring out the check engine light problem i had the same issue. Now I can go buy the purge valve. If u replace the canister vent valve get the purge valve as well, because that's the next one to go. Hope u guys have fun replacing this parts if a caveman can do it, you can do it as well 😂 save some $$$
