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!

[@moviefan62]

Hi Steve. Two things. One, My plastic tether ring came off my gas cap. It's still connected to the door and in one piece, but the ring came off the gas cap. Any easy way to re-attach it? Or do you suggest buying a whole new set? Two, speaking of which, I got this same check engine error code. Although my gas cap (without the tether) seems to be clicking and locking just fine, do you think this has anything to do with it or is it just a coincidence? I will have my mechanic check the canister purge valve if after I clean and/or install a new gas cap the check engine light stays on for over a few days.

[@jasonnasiry]

Hi Sir I have a mitsubishi galant 02 and P0456 always comes up goes away here and there but now staying on. Smoked it no solution didn't find any smoke took to another mechanic inspected car they say everything fine and changed gas cap but still on.. replaced gas cap like 4 times then just got the actual oem part from dealership mitsubishi for $60. then P0401 popped up and changed egr valve as mechanic said is the issue, engine light went away for 3 months but popped back up again with P0456. Is the issue i guess the evap canister vent valve or the purge valve. Any suggestions or help this code is a headache.. Thank you for your help..

[@macknumber9]

Is it mandatory that you delete the codes after doing the repair? I wanna make sure that I actually fixed the problem would the engine light go off after a certain amount of driving if I did in fact fix the problem?

Hey this code showed up for my 2016 Dodge Charger SXT. I believe it might be an actual leak because when I parked it in my garage I actually smelled the gas fumes. Should I replace the fuel vapor pump and clear the check engine light to see if that works?

[@nondainc]

Hi Tristian, have you double checked if there's any other trouble code registers together with this code?

[@shameermalik5540]

My jeep Grand Cherokee 2006 3.7 V6 smells of fuel vapors in the cabin and is giving very very bad fuel average. Also the code P0456. Should i also change the canister purge valve? I do feel vaccum when i block its lower slot.

[@nondainc]

Hi Shameer, while it is best to double check if there's any other code that registers along with P0456, inspecting the evap system including the purge valve, line, and canister is recommended.

[@shameermalik5540]

@@nondainc changed the purge valve just now. P0456 was the only error. It was sucking a lot of air and making hiss sound even when i disconnected the electric cable going into it. Seems like it was stuck on open position. Will reset the code and see what happens now.

Yes, you may apply these on your vehicle. These tips/suggestions will work if there's no other trouble codes encountered along with this code. Pay attention to your tank level and ensure that you're not leaking fuel.

If the code persists, please check more 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 Evaporative Emission (EVAP) canister or fuel tank leaks Evaporative Emission (EVAP) system hose leaking Fuel tank leaking

[@80nahman]

I have an aftermarket gas cap on 2016 es350 and the engine light came on. Could replacing the cap resolve the issue?

[@nondainc]

Possibly yes. If the issue will continue to persist, check the purge valve solenoid for any issue or the charcoal canister for leak then reset the code. Hope it helps!
