Hi, I'm Steve, nonda's lead mechanic engineer.
Feel free to leave your comments here if you have any mechanic questions, I will be glad to help you out!

if my car is having trouble starting after having the code come up could the canister purge valve still be a probable cause?
Hey Steve, I put my finger up to the purge valve with hose and electronic controls removed. I felt a slight vacuum. However, when I removed the part and tested it by blowing through it with my own breath, it held tight. Should I replace the valve or look elsewhere for a leak?

My wife has a 2004 Pathfinder and she got a p0455 code (evap gross leak, large evap leak). Took to the dealer, they changed charcoal canister, vent valve, purge valve. Then p0455 code went away, then we got p1456 code (small evap leak). Dealer then changed gas cap, still got p1456 code. Took back to dealer after 1 month, they charged $185 diagnostic fee, said it was stuck vent valve. I researched, bought new fuel tank pressure sensor and vent valve. I installed both, still got p1456 code. On my work day off, I got under car, removed canister (I tested it, good). I noticed rubber hose coming from gas tank to canister was stretchy, so I bought new fuel hose. I cut back a little bit of the purge line rubber hose (it was stretchy). Also I bought new clamps (ones where you use screwdriver to tighten). Installed the new fuel hose (that connects to the canister), 3 new clamps for the 3 hoses that attach to the canister (vent, purge and fuel). Bingo!!! No more codes pop up (no more CEL check engine light). No more evap leaks. Hope this helps somebody.
Thanks for sharing your experience, Tito Darden!
I guess I’ll follow your steps cause I have same issue
Stupid taking your 04 dinosaur to a dealer🤣
Tried everything you said except purge valve, going to try that and lyk
got this code after a fuel pump/ gas tank drop replacement and clean ( sugar in tank)...seems this canister thing might be it
Thank you. Went to the Auto parts store. They loan you the diagnostic tool - error code P0455. Saw this video --- cleaned the gas entrance (it has no cap) --- and Guala ! Engine light totally off. Spend 0 dollars thanks to the free diagnostic tool they loan customers and to you ! Thank you so much !
Did it say large leak?

Fixed my issue. Thanks!
In my particular instance I have a 2020 Mazda CX-5 and we had just changed the spark plugs, in order to do that the ignition coils needed to be removed, in order to do that, one of the hoses got unplugged on top but forgot to get plugged back in when everything got replaced. Easy fix
try cleaning the purge valve, drying, then adding graphite powder - it worked for me!
Thanks for sharing these tips, Bruce!
If you experience suction on the purge valve while the engine is running it "DOES NOT" mean the purge valve is bad, as the system will periodically open the valve during operation. It must be disconnected from the electrical source (to ensure the valve should be closed) then you should have no suction. Just wanted to help clarify this.
I was wondering about that, thanks for the info.
Thank you for all the tips
You're most welcome! Hope it helps!
Remember when you fuel your vehicles and to pump automatically kickes off. DO NOT!! CONTINUE to add more fuel. This over fills into the charcoal canister and causes this issue plus worse.
nice tip, thnx!
Thanks for the tip
cleaned cap and cleaner tank area worked thanks
Thanks was helpful..

These codes came back on my 2017 Toyota Camry XLE:
P0455- EVAP system gross leak detected

I have a 2013 Gmc Yukon Denali XL.
Have a 2015 GMC Yukon with the 6.2. Dealership replaced evap valve saying it was stuck open. But the code still comes and goes. Sometimes staying gone for weeks. And sometimes coming on multiple times a day.
Any ideas? Also bought a few new gas caps
Hi Jacob, please inspect if you have a fuel leak. Check/monitor the fuel tank pressure, and perform a smoke test. Hope it helps!
Me too. Have fixed all these parts too. Even swapped manifold gaskets last weekend. I noticed it happens when I sit parked at idle for a few minutes
I have a Ford Fusion 2011 3.0 V6 and I kept getting codes P0455 and P0457. I don’t have a gas cap and it seems to be clean and the check engine light actually popped on. It went away for a bit but then came back.
2013 honda civic p0455 code. I changed gas cap 2 months ago. The code went away. But came back today.
Would the purge valve create a whining noise when accelerating? I have an 09 Malibu 3.6 with a p0455 code with a new GM replacement gas cap.
Hello, it could be a result of a damaged purge valve or due to the leak in the evaporative emission.
I have code p0455 on my 2018 chevy traverse but i don't have a gas cap. I got this code 8 days after replacing canister purge valve for code p0442. Auto zone said code p0455 is the fuel tank pressure sensor

Hi, I replaced the purge valve and the canister on my 2014 Jeep Grand Cherokee Limited Hemi 5.7. It has code p0455 large leak. When I go to fill the gas tank, as soon as I am done, and try to start the car, it idles and won’t start. It gets stuck on the cranking, then it stops, and then I try again and now it turn on. It only does it when I fill the gas tank.
Same here
Pls check the possible causes:
Missing or loose fuel cap
Incorrect fuel filler cap used
Fuel filler cap remains open or fails to close
Foreign matter caught in fuel filler cap
EVAP canister or fuel tank leaks
EVAP system hose leaking
Fuel tank leaking
Try changing vent valve
Actually I checked again and got 0441 twice up down arrows and 0445 and check engine light. 2007 Lexus GS350 and probably wasted money on purge valve and gas cap…. Help
Yes, if you have P0455 code (large evap leak), then replace 1) charcoal canister, 2) vent valve, 3) purge valve (change #1 first, drive if get same code, replace #2, etc...). Hopefully P0455 goes away then you may get P1456 code (small evap leak), then replace rubber hoses that connect to the canister
Thanks for sharing your knowledge!
Why not find the exact cause of the problem? Save money & time.

Hello,i have a 2005 mazda 3i, i already changed gas cap with a oem gas cap and changed purge valve and still have code P0455 and also, there's a gas smell when i drive. I already checked under car and see no leaks and already took my car to two mechanics and both of them said they don't smell anything or see anything unusual. Any suggestions??
And also , i've been at the gas station and the pump would stop at let's say 2 dollars and then i pump it again and it stops again and after that, pump fills up my tank fine.

Hello, since you are receiving multiple codes, we suggest getting your vehicle visually inspected by your local mechanic for further diagnosis.
Does this cause engine stall out
I checked mine and felt vacuum suck -age from the part that was clipped onto the valve. Wanted to know if I did it right or if I was supposed to feel suck - age from the end of the valve itself? Thank you for the video

@@nondainc also is the canister purge valve that I’m supposed to test for the vacuum suck-age in the front or back? When I did it I disconnected the hose and the car shut off and I felt suck age from the hose. Did I test the right end? Is their an email I can send the video of me testing it so I can be guided to the best possible solution?
Hello, it's in front. Have you scanned your vehicle to verify the trouble code present?
@@nondainc thank you for your reply and assistance. I went to Autozone multiple times to do the diagnostics test and the code that pops up is P0455 the large EVAP leak. I followed your instructions and did fill suckage and just wanted to make sure it was the valve not allowing air to come up because they do not do returns on parts. Since it’s only like thirty some bucks I’m just going to get it and install it rather than waiting and something like an O2 sensor becoming effected.

Hi Usama, we suspect that the gasket (attaches the sending unit to the to the gas tank) is faulty. The fuel tank pressure must be checked and monitored. We also suggest to perform a smoke test to confirm if the EVAP solenoid and valves are functioning well.

Hi Corey, when it is in a good condition, the vacuum will hold very well and it won't drop even after a minute. Since the canister purge valve was also replaced already, it is recommended to have the vehicle inspected by a certified mechanic to determine the problem.
