Hey folks! I have a 2015 Kia Cadenza Premium. Anyone else dealing with a reoccurring check engine light with a code P0456? It’s a “very small evaporative emissions leak” I replaced the gas cap to no avail. I found a replacement evap purge valve online for like $20, but wanted to see if anyone has any ideas before I try it.
Thanks in advance!

Hi There, I just received an P0455 error gross leak evaporative emmisions system... I ordered a gas cap from kia parts, if that doesn't do it then next step is the purge valve.. Your on the right track, I don't know where the purge valve is or cannister...

It would be a good future reference for any updates if the new evap purge valve cleared the code.

I had the same error too, replaced gas cap same error, took it to my regular mechanic, he found a different error code, but the fix was a plug that goes into the air intake just before the air filter area, he said it was loose . Give it a try , its right there in plain sight.

Update: the Evap Purge Valve DID NOT solve the problem.

The evap purge valve didn’t help. I will try this today. Thank you so much for the suggestion! Maybe it’ll save my day!

ANOTHER UPDATE: Nothing seems to work, so I’m just going to continue to clear the check engine light about once a week! Lol. Still love my Cadenza though haha
