I got the dreaded p0456 CEL.... new gas cap and now leak detection pump. My cel is still on but my evic is now just displaying dashes instead of a code. Does anyone know if the pcm temporarily stores the code even though it sees no current faults?
My name is Cody and I hail from Battle Ground WA... I bought my first jeep nearly a year ago now and have been slowly building my 2014 JKU with a lot help and sifting through all the great threads in this forum... So thank you for all the awesome advice
