Alright guys, does anyone know anything about error code P144C? I am half way through driving from northern washington to San Diego and I have gotten this code 2 times a day for the last 2 days. After I clear it it takes 4-5 hours to come back. All I have found about it is it's for the "Evaporative emission (EVAP) canister purge valve". Any help would be much appreciated.
