kedge Posted May 3, 2024 Share Posted May 3, 2024 Hello folks! I started getting the P0456 error a couple of months ago on a 2019 Edge SEL. I see a post from 2017 about the vacuum purge valve, so I'm considering replacing that if I can find the correct part number. I've also seen reference to the gas tank fill flap (capless) getting dirty and staying open a little so I'll check that too. What I've noticed is that after I fill up, when I try to start the car immediately after filling it usually takes two tries for the engine to get going. I'm wondering if this symptom is pointing to one over the other or something else entirely? Quote Link to comment Share on other sites More sharing options...
kedge Posted September 29, 2024 Author Share Posted September 29, 2024 (edited) Just in case someone else stumbles upon this, I replaced the purge valve assembly (K2GZ9D289A). Problem fixed. Edited September 29, 2024 by kedge Quote Link to comment Share on other sites More sharing options...
User19432 Posted March 26 Share Posted March 26 Has this fixed still held up? I have a 2019 Edge SEL & 2020 Edge SEL both with this code coming back every week with no fix working so far. Quote Link to comment Share on other sites More sharing options...
