Thanks for sharing this info; in the same spirit of sharing, I will present another possible source of a leak. My 2004 GMC Sierra 1500 (also Chevy Silverado) developed a 'small leak' problem, which was caused by the top of the fuel module rusting completely through! You can literally see several tiny pin holes in the thin steel top, not to mention the rusted large hose connector that easily broke-off when I tried to disconnect it. I removed the bed (8 screws & 3 connectors) to gain access to the top of the tank, replacing the 145,000 + mile original module with a new AC-Delco OEM unit. New pump, pressure sensor, level sender, everything. Being a GM in Indiana has resulted in a good bit of rust trouble, including the rear brake line, the fuel module & the body. The top of the fuel tank collects dirt & sand & never gets cleaned. If you have an EVAP system leak you can't seem to find, you may check the fuel module or however lines & the pressure sensor connect to the tank. Cheers! DD
I believe that you're intellectual expertise helped me calm down and focus on my 2000 ranger. Thank you so much and here I go back in the ring for round 16.
I'm only into the video 3 minutes so far and I have to say that is the best simplified explanation of the evap system that I have heard and I've been watching videos for days trying to figure it out looking. I'm forward to the rest of the video. Thank you my friend.
I'M ABSOLUTELY BLOWN AWAY YOU ARE THE ONLY THAT HAS EXACTLY IN DETAIL WHAT I NEEDED TO KNOW WHAT WAS GOING ON WITH EMISSION PROBLEMS YOU NAILED IT, I'M DEFFIENTLY GETTING IT FIXED. THANK YOU SO MUCH FOR MAKING THIS VIDEO. EXCELLENT MECHANIC GOD BLESS YOU 🙌
Dude, your video pointed out the cause of my P4055 code I have been chasing for almost 4 months... I have replaced every component in the emission system and was in the process of chasing vacuum leaks.... your video pointed out an area I my not have found. Thank You!
Nice job man, I just found a similar issue on my 2001 mustang, I had the rear end built, with gears, welded and trued tubes, a nice cobra limited slip, moser axels, and a moser cover, that cover, is the same as ford racing cover, or many other cast aluminum covers, it has a sharp edge that sliced the evap line, that hose sits right in the differential valley, the new girdle sliced right into the line, bet many who have a built rear end have the same issue, evap leaks are a pain, even with a smoke machine and a bi directional high end scanner, good job fining the leak you had. And finding it, they are a pain to find.
Dear sir.im stephen from the uk. This video has been byfar the best desciption of the evap system my far.. Very clear,exellent camera work,and very methodical. I learnt a lot.very helpfull,thanku.just subbed keep up the great vids
Great explanation of your PO455 issue. I'm glad your video is still here I usually download these but need to. Just have to get off my A Double Snakes and just look as you did. Take it easy peazy! 2004 Ford Tang GT 302 4.6L
Bravo! Love when we/ you follow up. There are many videos that leave us hanging. I am your 400th like, and I subscribed, mostly because you're a natural at this.. I'm chasing my 455 on a 2003 VW Passat. After changing a 30 dollar part, and the light came back on... and then replacing the fuel cap, of which the SLANT brand did not solve it either. What Slant did was make it very hard to open as its a shitty brand fix. No way could a lady open her fuel cap, period. So I will be putting fresh batteries in my flashlight and get down under... Thank You.
Awesome info; thank you! One minor critique though is how shaky the camera is... I was very dizzy and had to watch your video in segments. But other than that, it was great! 👍
Noticed that the new hose was touching a sharp edge on the bed. Hope you saw that and adjusted it. Was that rodent damage to that hose? Also noticed a hole in the wire loom next to that hose. Might want to check those wires for damage. Good video.
I’ve got 93 ranger that nobody will touch because it’s older with an EVAP leak won’t pass smog. I guess it can’t be plugged in to tell what’s wrong with it. I’ve got one guy told me if it didn’t need some pressure test on it that he night be able to fix it. You didn’t seen to run and pressure test. Am I getting the run around. Is it old enough that a code can’t be gotten on it?
Replaced my canister purge valve and for some reason after my vehicle warms up and I turn the key and I am getting this gurgling noise coming out of the fuel pump area by the way new fuel pump.... If I cycle the fuel pump about 10 times the gurgling noise goes away and my vehicle will start.... It only does this when I drive to the store the vehicle sits while I'm in the store I come back out and I have the gurgling noise coming from the fuel pump area
I have a pt cruiser 2001 , I'm a 69 yr old woman and have a 0455 code. I have fixed my gas cap, and now I'm working under the hood checking the canister purge valve. Do I just go to you tube to find schematics for my pt cruiser?
Awesome bed. I have no engine light on. But hooked up computer just to check the system. That shows evap issue. Didn't know what that was. I will investigate now. The 03 Ranger stalled once on my wife. Not on me. Was wondering if I could find a problem. this doesn't sound like it wouldn't have anything to do with
let your peeps know disconnecting the battery can make the check engine light go away, but it still won't pass emissions inspection, it just causes "Not Ready" codes, and that makes the computer at the inspection shop spit out a "fail", can't take a "fail" to the court house for new registration tags...damned gubmint!!
Yea its not it will only make your gas mph go down in other words your gas vapors will easily leak out and you would be spending alot of money on gas than you normally would which to me is very mandatory I'm having the same problem with my 2008 chevy impala.
Loved the info vid. I have slow fuel delivery. The gas pump nozzle cuts off constantly will filling. Any suggestions? Someone recommend "Vapor Canister Purge Valve" which I think is located behind the left rear tire? Have you expierance this problem? Thanks for your help
Nice...but why clear the code? Wouldnt the fix itself have made the check engine light go out on its own?.....Then you'd know for sure that was the Only leak in the system
I have a p0455 code on my 2004 impala 3.4L I'm burning a ton a lot of gas also...could this be a canister purge valve or just a hose it's also paired with a p0401 code as well which is a egr valve insufficient flow idk where to start on my car, plz help thanks
My Kia optima dtc 0455 came on. Cheap scanner erased it. I do this about 3 times per yr. I live in Virginia and never fall inspection at AAA ,,always have eng light off
@@MrJed40 get under your truck and look on top of your gas tank with a flashlight it's a tight spot to get to and it's a small hose will be on top of gas tank
I drove for damn near a year. Just fixed it yesterday on my Grand Prix. I had a few evap codes so I tested and replaced the purge, charcoal canister, tank vent valve, vapor canister and finally the darn gas cap. All codes gone and my cars acceleration is back! Good video sir!
FYI pressure is PSI pounds per square inch. One can never have 10 psi of vacuum. If the person in the video does not know this is, it safe to say that he doesn't know too much about the rest of it?
I really hope this is it. But got smashed into twice (parked legally!!!) 3 mo apart and check engine light came on after about 2mo after last bash in. Damn.
