Hands down one of the best videos on this subject on the entire internet. This was like going to class and learning a lot! If you have P1456 P1457 error code on your Honda start by watching this video and then get informed about the specific features of your Honda. I was getting P1456 and P1457 and guess what? It was the two-way valve on my 2004 Pilot. With no special equipment I got the parts off the vehicle with the canister and the canister vent and canister passed. Then I tried the two way valve still connected to the bypass valve by blowing from the canister side to the tank side. The one on my rig leaked! I replaced with a confirmed good valve form the scrap yard and CEL off, tags on the way! Thanks, Big Dog50001!

I will second Kelly Myers' comments. This video is FANTASITC. I have a 99 Accord EX. In the end I replaced the Canister and Purge Valve. The whole thing was one rusted blob after 22 years in the north. The information in this video educated me on how the whole EVAP system works in general. Translates to most vehicles.

[@BigDog50001]

Glad it helped, thanks for the comment!

[@typhoon320i]

This is a good walkthrough. I have a P1456 on my 2000 2.3 ( not gas cap) I would love it if you had one of these videos for that code.

[@BigDog50001]

No I don't have a video on that code but I would fix it in a similar fashion, seal system and find the leak or bad component that is fooling the computer into thinking there is a leak. The computer looks for changes in the fuel tank pressure during certain testing conditions and when it doesn't see the changes it is looking for it sets a code (after 2 trips). Fuel Tank Pressure Sensors, Vent Solenoids, Two Way Bypass Solenoids and Check Valves, cracked/broken/plugged hoses, Charcoal Canisters etc can all cause that code. Some models are susceptible to charcoal being sucked into the lines and clogging the purge solenoid and lines to it. Thank you for the comment!

[@aznnp77]

This was a great explanation of the system. Unfortunately, I've replaced a ton of stuff and still get the P1457 code. My issue has gotten worse in the past 2 weeks. Now every time I fill up gas, the car just cranks and won't start for the first 3 tries. After that, it will start, but stall out 3-4 times. After that, it will eventually stay on and drive perfectly normally until I fill up the gas again. I've changed the Charcoal Canister vent valve, then the charcoal canister assembly with the vent valve, the purge solenoid in the engine bay, the fuel pump assembly, and the gas cap twice, and the O2 sensor. It went away for a while when it first showed up a couple of months ago, but now it comes back every 2-3 days. Issue is starting to cost me a lot of money in parts and labor. One thing I'll note is that my fuel trims are high, but not high enough to trigger the lean code. My long term fuel trim is around +7/8 most of the time. And my short term goes to 0 if I'm coasting, but seems to rise at idle when I'm at a traffic light. Can you give me an idea of what else it could be? I need help. I smell gas after struggling to start after filling up, but I don't notice it after that.

[@adamstein2691]

I think I beat the P 1457 code! Changed the evap canister and the canister shut off valve. Cleared the code and hopefully the engine light won't come back on. Going for emissions testing this morning. I did have to pay the oil change mechanic to loosen that one pesky 12mm bolt that held the canister to the frame and then drive back slowly the next day to have him screw it back in again. I'm in the rust belt too-WI. Parts $100+60. Mechanic estimate >$750 Big savings!! Thanks for the great informative video!

[@dravenknight8404]

Oh my God I love your videos. Unfortunately I ain't too mechanic savy. I have a problem that has plagued me for about a year and lost about $300 on it. My vehicle is an 06 Honda Element California Emission originally, the vehicle is no longer in California. It started out with a p2422 evap vent valve stuck shut. The vehicle did not want to take gas when refueling. I paid a shop $200 to supposedly fix it. They say they replaced the valve. Three hundred miles later the code came back. I called them up and they were pissy about it, so I said screw it I will fix it myself. The shut valve looked like an original part, so they either did not fix it, or they put a used part on and charged me for new...or maybe they put a different part on instead of the valve. So I went to the junkyard and replaced the canister, canister vent valve, fuel pressure sensor and the seperator. Its been about 2k miles and the check engine light has stayed off, but I got a new problem related to it. I can hear multiple puffs of air coming from the evap system while running. I removed the gas cap while running and the vehicle stalled. I put the cap back on and started it. To my surprise there were no more puffs of air until it ran for a few minutes. The sound came back. I am at a loss for what to do next. I do not think the parts I put on were California emissions though, if that matters.

[@BigDog50001]

Some of the parts around that time frame are different depending on whether it was California emissions or not, so that might be an issue. I would double check all my work and make sure all hoses and connections are good (many times if a line is not connected properly you can hear a noise when the computer opens the purge valve). Unfortunately, without seeing it anything I tell you would be a guess. Thank you for the comment, I appreciate it!

Don't know if you'll see this but. My 98 accord is throwing both codes 1456 and 1457. At first it was only throwing 1457 i believe, my scanner said it was a tank side error. Should I just start by changing the vent solenoid?
