EVAP SYSTEM EXPLAINED & P0455 GROSS LEAK SOLVED

Here's the OBDII scanner I use on Amazon: amzn.to/2GFTGvL

[@dimplesthebus1133]

You did an awesome job in explaining the fault code, great follow-up too. Thank you for not leaving us hanging.

[@DScottDuncan]

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.

[@billlyons2857]

that was a great video! got more from that than ANYWHERE on the ranger evap. you are good at this. thanks

[@michaelturner7641]

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.

[@fawnbutler9158]

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 🙌

[@brianandkimberlycarroll1584]

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!

[@motoforlyfe]

Thanks, glad it was helpful!

[@train4905]

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

[@cliffordyates2114]

Great job! a lot of good info. Helped to understand more on the system

[@roymorgan5498]

Thanks Bud! Going to see if my hose is torn or broken off. Great video! 👌

[@chippsterstephens6800]

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.

[@jesuscrisis435]

Thank u for this video. i got the same code today and your video was very informative in a way i could understand clearly

[@tomvanalst8533]

Good troubleshooting video, detailed. What ID hose size and length?

[@369VJ]

This is the best explanation what the beginners need. Thanks

[@rufusrunsgsp4610]

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.

[@motoforlyfe]

Thank you very much! I appreciate the kind words! Best of luck!

[@ajman01]

Great video! just crawled under my Ranger and fixed it in less than 5 minutes

[@toddadamsaz]

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

[@toddadamsaz]

Sorry was thinking of my 5.0 truck "302" actually "281" 2012 F150 FX4 5.0 302...Geez can't wait for the feedback!

[@jimmyprater7546]

Thank you, my dads 2001 Ranger had the exact same issue, simple repair

[@glenngonzalez2647]

Great vid Moto! You sent me down the right path to fix my prob. Thanks again for the help. 👍🏻

[@motoforlyfe]

Thanks Glenn!

[@elgarfio4186]

Thanks for taking the time to share this information with us! Well explained!

[@georgebackjr6194]

Thank you. I hope that is my problem and I can soon fix it,

[@dustinbeckhamnew]

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! 👍

[@robertcornelisse8664]

Great video, you should definitely make more video's.

[@cards06champs]

I have same issue and code with 2006 ford ranger 4.0. Hopefully it'll be something simple as well. Nice video!!

[@paulmonk7820]

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.

[@cjbcarr1]

this helped me a lot with my ranger. thank you!

[@Carballoca]

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?

[@worshipwhilewewait]

so what was the hose hooked TO? canister purge valve? Fuel pump? What? never explained that...

[@timszon]

Great job! Nice work following up the results in the same video clip. Do you know where to find the evap system purge in a mazda 6

[@aldownsouth8355]

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

[@ecmjr]

Good video, just got the code on my 01 Explorer. Nice truck by the way!

[@The_Doctas_office]

what is the name of that hose and what does it connect to?

[@kellydees1938]

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!!

[@mariewarzecha6941]

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?

[@motoforlyfe]

I would check google, you might have more luck finding diagrams there!

[@Libdiddy]

Sometimes better just to buy a haynes manual also

[@marksz06]

Where did the other end of that broken hose run to?

[@billr2584]

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

[@REALCEDRICKBATES]

They did for me purge canister but my light is still on

[@paulmonk7820]

Purge solenoid/valve is in the engine compartment. The vent valve is usually attached to the charcoal cannister back close to the gas tank.

[@alfredosanchez2677]

Were exactly was the hose ?

[@lorenzobegay5886]

I have the same problem as yours but mine is P0 300 I have a 2005 Ford Ranger edge 3.0l...If you can tell me what that means

[@mattjd8]

Great Evap explanation 👍🏽👍🏽

[@miragexl007]

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

[@motoforlyfe]

Thanks, good luck finding out the problem!

[@nathinking1712]

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

[@2Jeezuzisreal]

Thank you great video. Is it unsafe to drive with a evap leak thanks

[@soylentgreen2065]

It is not

[@Deeply152]

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.

[@brendakleinharris6333]

Mine has the same code but it says large leak. Is that the same as gross leak?

[@cookiesaregoodtoeat6612]

Yes

[@skiz72]

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

[@ThundaBeast]

Excellent explanation man

[@germanium1872]

Best video on the subject. Thanks man

[@peterhannam855]

2010 Ranger , engine light on and difficult to put gas in tank . Have to fill very slow . Any ideas .

Had same issue and replaced the gas filler neck, easy and took care of the problem.

[@timlee4527]

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

[@Killmaisy]

Replaced gas cap (was broken) and still have check engine light check gas cap light. How many drive cycles until the lights go out?

[@lohengrinknight]

Get OEM gas cap.

[@thomasbatts672]

Thanks man had the same color ranger same model and same broken hose

[@MrJed40]

Where exactly is that area? Looks like it's close to the cab but what side, passenger or drivers side?

[@thomasbatts672]

@@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

Where aprox was that hose that was broken

great job explaining, thanks

[@bluecollarpockets1959]

Thanks for the info brother you saved the day

[@motoforlyfe]

Thanks glad it was helpful!

[@bigmike9128]

Is this damaging to the vehicle or dangerous?

[@joeyd.OEF.2010]

Not at all....It just let's fuel vapors go into the atmosphere instead of back to the intake manifold.

[@bigmike9128]

@@joeyd.OEF.2010 thank you

[@ajseuol1864]

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?

[@thalegacy6]

I think he helped solve many other problems judging by the comments... Maybe he messed up and didn't catch it.

[@nicholasminor3806]

How long could you drive with a pO455 Gross leak?

[@thalegacy6]

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!

[@C.Church]

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.

[@C.Church]

Crash 1. Gas cap side rear. Crash 2. Direct rear 😡

[@motoforlyfe]

Hope you're able to find the problem!

[@chucksavage1980]

Will a evap leak cause the vehicle not to start ?

I think it's pretty unlikely.
