1998 Honda Accord Question: where is the canister purge valve
Answer #1ziptie12 June 20, 2012, 13:02Master
That code (along with p1457) refer to entire sections of the evaporative system. Scanner , vacuum gauge ,service specs. recommended to diagnose so you don't spend more in un-needed parts.Most common part in my experience is the canister vent shut valve (CVS valve) which is on the end of the canister by the gas tank two phillips screws a two pin electrical connector and vacuum hose . Can be a nuisance to remove screws.
