Thanks for emphasizing using an OEM gas cap. Your statement that 80% of these codes can be eliminated (by the right gas cap) made me purchase a $24 gas cap at the Chrysler dealer and to toss out my $12 aftermarket one purchased at Autozone. Comparing the OEM and aftermarket side by side you can see the OEM is designed to seal much better. You saved me a lot of stress and money days before my daughters wedding!
After trying everything from gas cap, smoke test, new hoses and a new fuel pump seal for 4 years and still having the engine light come on with the P0455 code, I finally pulled the cluster panel and pulled out the engine light bulb and smashed it. After 4 years of dealing with this stupid code, I finally said enough was enough. Jeep still runs great.
In Calif, we are forced to pass smog checks very two years for 'clean air'. Check engine light and any 'leaks' will FAIL your car and then you can't get registered for the next 2 years.
I was just thinking that an emission leak really isn't going to hurt anything anyway with functioning of engine and driving? I wouldn't sweat it too much. I have a bimmer and got the same code as you. I think it's the canister purge valve but I could play part games all day. Buy this but that, fix this fix that and not know. Gas cap I doubt it. How does a new gas cap fix it 80 to 90% of the time? If I'm wrong, and those stats are right forgive me now.
Great, Concise yet thorough checklist and explanation of most likely items! Not Too wordy, Not too brief! and appreciate you putting them in a bit of sequence of Most likely possibilities! Thanks a million!
Thank you! To the point and very informative. Finally a channel to subscribe to so I don’t have to sift through all the random (hardly helpful) videos out there. Well done!
Thanks for sharing this video. We just bought our daughter a 2009 Hyuandia Accent. We believe the purge valve needs to be replaced as this is a common problem po456 code came up when tested. Thanks for your clear precise explanation. Also, the following codes came up 300 303 and 304. They are all misfire engine codes. The guys at the parts store told her that it may be a spark plug, or wiring. This was in cylinder 3 and 4. Thanks again.
thanks for the information. I've been reluctant about paying $500 to the dealer to fix evap canister and hose on my 2004 Navigator. I just may purchase the parts from Autozone and have a mechanic put them on.
In my 2011 Jeep Wrangler Unlimited, I am getting a P0457 code after a check engine light and gas cap indicator light is on. I bought the new factory gas cap, but it didn't clear the check engine light nor the gas cap light. I tried clear the code, and then it just came back on after 30 miles. I went to the dealer, who did a smoke test, but couldn't find anything from it. They wanted to then pull the gas tank off to look at the line from the gas cap to the tank, as well as the connectors/seals there. This would have cost 450, so I put the brakes on them doing it, as the smoke test didn't reveal any leaks. So, I took a more trusted friend, who is going to do the smoke test again. I actually think it has to do with the vent valve sticking open or the cannister purging valve. Everything else runs pretty smooth on it. We update everyone when I know more.
Be careful. Sometimes when you replace a part and that was not the problem it takes a long time for the code to come back especially when its a small leak at the fuel pump , until it's worse. That is actually the most common cause 2007-2009 Sonatas. When my mechanic replaced mine he insisted on using OEM because he had too many comebacks on aftermarkets with altered design.
Great video! I really appreciate the simple yet thorough explanation, as well as the pics throughout giving a visual to the part or tool being mentioned. Videos like this are what's great about UA-cam. P.s. it was my gas cap. (07 Chrysler town and country)
Wow, this is first time I got the information I'm looking for, you did not beat the bush (around and about) to give information that will help Thanks you for taking time to explain what the code mean,
Thanks for the video. I have a 2013 Dodge Durango. Rather than replace the gas cap, I cleaned it with the proper cleaner. And, I reset the check engine light by disconnecting the negative on the battery. I used Blaster from Autozone. Cleaner must have petroleum-based lube. So far, so good! No check engine light yet!
I did that with my mom's Old 2012 Acura. Nightmare finding the radio security codes. Good post, thank you. And when you do change the gas cap it takes at least 24 to 48 hours to clear. And what I've found it will clear, just a little patience. After 3 days and isn't clear. Continue troubleshooting.
This is a great video! I just returned the after-market cap and put the original one back. The check engine is gone! So I endorse only to buy genuine cap if you are interested to permanently fix the problem.
Great video. Quick question: I have an cel code p0456 on my 2013 Corolla S. Had a smoke test done and smoke was coming out of the gas cap. Replaced the old cap TWICE, both OEM models, and I still get smoke coming from the gas cap along with the p0456 code. I checked the filler neck, fuel lip, gas tank, etc. Shows no signs of corrosion whatsoever. I need to pass emissions, help!
I agree with Bob No. Most times these codes come on because of the vent valve are faulty or not sealing because of dirt inside. You can usually remove them and take them apart and clean them with compressed air. Most of the cars I work on drive several hundred or more miles a year on gravel roads. Sometimes the vapor canister or lines are cracked due to flying stones. ( windshield repair companies make a killing here!) If you don't drive gravel....maybe check your gas cap.
would a swollen check valve inside the tank cause this? it seems my 2006 300C had the warrenty upgraded to lifetime because of this valve being messed up and filling the gas tank causes the car to stall.
Ok for the Ford Focus 2012 model they don't have a gas cap the mechanism inside of it will move will by a magnet when you put the gas nozzle inside. So would I have to take my battery out
I replaced the cap because of a PO456 ... the light stayed off for 5 days and then came back on. It has done this 2x now. I will try an OEM cap next --maybe the aftermarket caps are missing a slight design difference that the OEM one has...
So i got a question. I got a 2007 caliber. Well yesterday i ran into an issue, i took care of the issue. But when resetting my code i noticed in my live data on my obd2 reader. That my evap wasn't registering. It had a red x instead of a green check mark. Any thoughts on why that could be??... Theres no codes pulling for the evap though
I was doing a smoke test in my 2003 chrysler town and country and I saw smoke coming out of the vent valve. you think that is normal or I need to replace it?
My trailblazer threw a "loose gas cap" light so I unscrewed it and screwed it back on. Same day it went off and now I have check engine light. You think it's the gas cap?
I've had vapor hoses, the fuel tank pressure sensor, a plugged filter which is in front of the Canister Vent Valve cause Evap codes on various vehicles. Then it got more interesting with a small leak from the seal thats between the fuel tank and the fuel pump module. Many of these problems were located using the "smoke machine " which can be used to locate leaks from air exiting the vehicle with the windows up, doors and vents closed. If your vehicle's Heating, Ventilation and Air Conditioning, or H.V.A.C. system is vacuum operated and has a leak like a hissing sound, the Smoke Machine can help find the leak. My worse Evap problem was a Powertrain Control Module or P.C.M. the would INTERMITTENTLY not turn on the purge or V.M.V. valve, which would not allow the gas fumes to be purged from the fuel tank. THAT ONE WAS A FUN ONE ! ! !
007conspiracytheory WOW! That was over a year ago, but the memory of that one is fresh like it was yesterday! While watching the Ford IDS on our laptop, it was showing the P.W.Modulation happening with current being consumed, BUT, no vapor flow! I put my digital multimeter on the PCM pin that grounds the purge flow solenoid coil. with the engine running, I manually (through the IDS) turned on the purge valve, the DMM changed from 14.3 Volts to about .1 volt or less. We have vapor flow. Turned the purge valve off, DMM returns to charging system voltage and no flow. paused a few seconds. Turned on again. DMM changes normally, we have flow. Turned off, no flow, DMM back to charging voltage. Paused. Third time, same thing. Paused. Fourth time, DMM shows PCM trying to ground the purge valve coil, but cannot, voltage returns to charging voltage. Paused. Tried again. This time the third time was the charm! Turned off engine, waited about 1/2 hour, tried again. Third try was the charm! Installed a Reman Ford ECM, retested, all well in Ford Land! I learned that multiple tries trick several years ago with a different vehicle and a different electrical problem. HTH. Mike
Hi: Thank you so much for making this video. I scaned mine (CIVIC 2003), it says P1457 EVAP control system leakage (EVAP Canister system). I disconnected my battery, and it worked for one week and is on this morning. I am planning to buy a new gas tank cap tonight. Is there anything you would suggest/share? Thanks again.
I have a 2010 Ford Explorer Sport Trac with the 4.0 engine. I'm getting the PO455 code. Check engine light is on. I can't find the canister purge valve to replace it. All the videos I see shows the older models or the 2.5 engine. Can you tell me where it is?
I have a 2012 Honda Civic, the p0455 code came on for one day but it disappeared. I did took care of the cap the day when it appeared. The following day it disappeared. My check engine never came on. Should I still be worry about it?
2013 Dart ONLY 50K miles PO456. Gas cap seal looks fine & cleaned the inner tank spout. Still throwing the code. Should I replace this pump & if so I can't find the part #? TY
I got the code p0456 on my car just this week and my car started making a noise underneath my car not sure where it’s coming from, but it sound like a screeching noise underneath the gas tank area not so sure what is the problem and I don’t want to get ripped off. Will appreciate the help
I had a p0455 code that came on 5 months ago. I reset the battery and it turned off. Recently, it came back on but after 5 monthd and about 1000 miles. What does this tell me about the problem? I do smell gas near the gas cap after driving. Thank you!
I have a 2012 Dodge Ram 1500. My issue is making my truck periodically lock up and turn off. I have a code of P0456 but no check engine light. I will try to replace the gas cap first but if it doesn't work we will examine the hoses. Any other suggestions?
pls do u kno were to locate this large leak on mercury mountaineer 02 thanks say 455 large leak only cod, last time it was 401 but just change the gas cap with factory type every cod went off this time come back with 455 one cod thanks
My wrangler x is tripping the p0456 code and I’m almost positive it’s the purge valve. Mainly because I’ve also been having issues starting up every few days
Well, our 09 Escape still will not start... after changing out fuel pump and the purge valve....still getting the P0457 permanent code ..any hints? tnx. I did try to clean this filler opening a bit..but this should not prevent vehicle from starting........and check engine light was not on.. except in accessory...
Great info thx......my wife bought a after market gas cap I'll go to ford and get a real one pull the battery cables and see if that does it if not then a evap test.....sounds like I know what I'm talking about
OK just went through a P0455 on a 2015 Kia soul for second time. Found out my new Amazon OEM gas cap was not seating right and daughter was not tightening it all the way. It is tight going into the fuel tank hole (zero tolerance) and then I can turn it and make it click with it not being set in all the way. The trick with mine is I have to make sure it is aligned on the threading then push down (It's a little fight to set it right) and it will go down about 3/4 of an inch then I can tighten it and my cap clicks. Reset error code and didn't come back. Had a training session on twisting that specific gas cap. It just needs to be broken in.
Technically smoke is last , pressurized nitrogen with data list monitoring is preferred along with "snoop" or soapy water on all connections . The other problem is that restrictions register as leaks on older software and cars so smoking is less than ideal.
Great vid my man. Quick question. If my check engine light is off, but I'm still getting the P0456 code, could that still be the gas cap? The mechanic told me it was the canister, I'm not trying to get ripped off. I already paid $100 for diagnostic.
So you strongly recommended a original gas cap ? Or I should wait the three days and see if the light don't come back ? I'd get those two codes with orreillys and the guy reset the codes Thanks for the good info
Original owner of Dodge Durango here.... 280K mi... All emissions trouble codes were resolved by replacing various section of vacuum lines or just fixing splits with gasket Silone sealer and rapping with electric vinyl tape from auto parts store.... Only replaced gas cap once because I didn't realized I was lied to by the dealership.
Good video bro I have a 2005 Santa Fe and my mechanic told me to get new gas cap and I just bought one from Auto zone and he reset the codes and about 2days later the check engine light came back on. And you said a person should replace the gas with the original factory gas cap. Should I try that before I go get a smoke test?
Question if i replace gas cap and have the check engine light reset. I was told here in arizona that the inspection center can tell the engine light was reset and you will fail inspection. Do you know if that is correct? Because if i buy the gas cap and can't reset the engine light it won't pass inspection any way so I am just confused. Thank you
i open the radiator cap and and it seams may be it was stuck preventing overfllow in the countainer creating pressure in tube and causing leaking of coolant making strong smell in the cabine. i remove the code p0456 and it did not came back

Now That's how you do a you tube video. Great, professional and to the point which most of us like. Congratulations on a great, helpful video.
Great video young man. I'm an old car guy from way back and the newer vehicles are not always to diagnose the problem. Thanks again.
Thanks for taking the time to put this video together. It was very clear and helpful!
This video legit just solved my problem. Check engine light gone. Thanks man
Thank you! To the point and very informative. Finally a channel to subscribe to so I don’t have to sift through all the random (hardly helpful) videos out there. Well done!
Changing the gas cap worked for me. Thanks!!
Reset the computer and away I go!!

thanks great video, perfect way to show n explain how to fix the problem... thanks again
Mine was the gas cap !
Bought after market, didn't work on my Altima.
Bought from dealership $28
Worked.
Love the explanation . Very easy and reasonable . Thanks a lot
Love the Lava Lamp decor!
Nice video, good help. Thanks.

Dude thank you! between my honest mechanic and you... i'm happy!
i own a repair shop and indeed %75 are gas cap related
My issue was the fuel cap. Thank you for the great video, it really helped me!!
Excellent video. I replaced the gas cap. Waiting to see if the light comes back up.
Thanks for the excellent information !!!
Video is very helpful, Thank you SO much!!!
Very helpful... Thanks a lot... Really appreciate you effort.....

Great video, dodge man over here 😁🤙
Thanks! It fix my problem without cost!

Great video, very useful and even entertaining.
Is this a common code for Pontiac G6? It kept telling me to check gas cap for a day before the engine light came on.
My trailblazer threw a "loose gas cap" light so I unscrewed it and screwed it back on. Same day it went off and now I have check engine light. You think it's the gas cap?

Excellent Video and best Advise
Hi:
Thank you so much for making this video. I scaned mine (CIVIC 2003), it says P1457 EVAP control system leakage (EVAP Canister system). I disconnected my battery, and it worked for one week and is on this morning. I am planning to buy a new gas tank cap tonight. Is there anything you would suggest/share? Thanks again.
I have a 2010 Ford Explorer Sport Trac with the 4.0 engine. I'm getting the PO455 code. Check engine light is on. I can't find the canister purge valve to replace it. All the videos I see shows the older models or the 2.5 engine. Can you tell me where it is?
Smoke machines will not help with very small or small leaks. Large leaks are typically a cap.
I have a 2012 Honda Civic, the p0455 code came on for one day but it disappeared. I did took care of the cap the day when it appeared. The following day it disappeared. My check engine never came on. Should I still be worry about it?
Great video dude; it helped me a lot. Thank you!
Very helpful, thanks man.
2013 Dart ONLY 50K miles PO456. Gas cap seal looks fine & cleaned the inner tank spout. Still throwing the code. Should I replace this pump & if so I can't find the part #? TY
I got the code p0456 on my car just this week and my car started making a noise underneath my car not sure where it’s coming from, but it sound like a screeching noise underneath the gas tank area not so sure what is the problem and I don’t want to get ripped off. Will appreciate the help
I had a p0455 code that came on 5 months ago. I reset the battery and it turned off. Recently, it came back on but after 5 monthd and about 1000 miles. What does this tell me about the problem? I do smell gas near the gas cap after driving. Thank you!
Great vid I will definitely try sone of these things you listed I had a P0455,And a P0456 pop up on my 2011 Jeep Patriot
What ended up being the issue?
I have a 2012 Dodge Ram 1500. My issue is making my truck periodically lock up and turn off. I have a code of P0456 but no check engine light. I will try to replace the gas cap first but if it doesn't work we will examine the hoses. Any other suggestions?
pls do u kno were to locate this large leak on mercury mountaineer 02 thanks say 455 large leak only cod, last time it was 401 but just change the gas cap with factory type every cod went off this time come back with 455 one cod thanks
you are the man thanks for this video!
Do you have to reset check engine light? If you make the correction will it go off by itself? Thanks.
My wrangler x is tripping the p0456 code and I’m almost positive it’s the purge valve. Mainly because I’ve also been having issues starting up every few days
Excellent job with the video, thank you.
Would putting an external 50 gal tank on it cause problems?
how many valves do i have for 2001 dodge grand caravan AWD 3.8. bought a solenoid valve. I have code PO455.
My 2014 Lincoln Mkt comes with a capless tank. Could this be the issue possibly?
AWESOME VIDEO, WORKED FOR US. FOR OTHER PEOPLE WITH BAD COMMENTS, THEY ARE JUST IGNORANT.
Thanks man, gas cap fixed my 07 Grand Cherokee
Thanks for the video! This is exactly what I was needing as I just through P0457.
Well, our 09 Escape still will not start... after changing out fuel pump and the purge valve....still getting the P0457 permanent code ..any hints? tnx. I did try to clean this filler opening a bit..but this should not prevent vehicle from starting........and check engine light was not on.. except in accessory...
Excellent video thank you for the info... 5 out of 5 stars.
my 2013 Ford Taurus does not have a gas cap. what would the problem be in that situation? since codes P0455 and P0457 are showing
Great info thx......my wife bought a after market gas cap I'll go to ford and get a real one pull the battery cables and see if that does it if not then a evap test.....sounds like I know what I'm talking about
OK just went through a P0455 on a 2015 Kia soul for second time.
Found out my new Amazon OEM gas cap was not seating right and daughter was not tightening it all the way.
It is tight going into the fuel tank hole (zero tolerance) and then I can turn it and make it click with it not being set in all the way.

Thank you, sir...on myway to buy a FACTORY gas cap.
Solved my problem immediately, Thank you Bro!
Good video bro I have a 2005 Santa Fe and my mechanic told me to get new gas cap and I just bought one from Auto zone and he reset the codes and about 2days later the check engine light came back on. And you said a person should replace the gas with the original factory gas cap. Should I try that before I go get a smoke test?
I replaced my gas cap on my caravan in a little less than 3 years ago. Could it be bad again already? I used the Mopar cap.
great video! thanks for the info, it really helped
Question if i replace gas cap and have the check engine light reset. I was told here in arizona that the inspection center can tell the engine light was reset and you will fail inspection. Do you know if that is correct? Because if i buy the gas cap and can't reset the engine light it won't pass inspection any way so I am just confused. Thank you
i open the radiator cap and and it seams may be it was stuck preventing overfllow in the countainer creating pressure in tube and causing leaking of coolant making strong smell in the cabine. i remove the code p0456 and it did not came back
Hey Bud. I have a 2002 Subaru and when I filled up the gas tank smell gasoline inside of the cabin, Could you tell me why. Tanks.
