Having problems with your 2003 Honda Civic ?
P1457 engine light is on
P1457 EVAP system problem
That code pertains to an evaporative emission leak on the "canister" side of that system. Most often it is the "two way valve" being contaminated with liqiud fuel but can also lead to more extensive troubleshooting. Good rule to follow. Don't top off the fuel tank when re-fueling. Not saying that this is the cause of the code but doing so can lead to liquid fuel getting to places it's not designed to.
