05 Honda Odyssey evap emissions leak… - EricTheCarGuy
2016年2月28日 · The purge solenoid is working properly (opens/closes as it should with power, and doesn’t leak) but the vent valve (at the canister) seemed to be pulling a lot of current, and wasn’t closing as quickly as it should. Replaced it, along with the gas cap (both new Honda parts) – no real change – still throwing the code.

I changed the purge solenoid valve in order to pass smog and also had a smoke test done to find any leaks-no leaks or problems with EVAP.
Small EVAP leak - EricTheCarGuy
2016年2月27日 · A smoke test is most likely the best way to track down the EVAP leak and check you gas cap. If you found liquid gas residue coming from the purge valve, …. My guess is that the tank had been over filled to the point where liquid fuel was drawn to the valve. BTW, I own a Nissan Xterra and randomly get this warning P0456 or P0442 with no CEL.
