The light on the dash, should do a bulb check when you first start the car. (bulb should illuminate for 3 seconds) after that the light will go out. then if there is a code in the computer it will come right back on . bulb could be burned out. a po 1457 is a evap code which is fumes or fuel vapores from the fuel tank .these fumes go through vacuum lines from the tank, back to the vacuum canister under the hood. then these vapors are purged to the engine to be burned with the fuel. you need to check all vacuum hoses going from the tank ,to the charcoal canister (vacuum canister) this is most cases about the size of a coffee can .around the front of the engine compartment. black plastic. with vacuum lines going to it. if there is a vacuum hose cracked, or off .it would cause a po 1457. service manual says- evaporative emissions ( evap) control system leakage (evap canister system) this problem is hard to repair eve for the skilled tech good luck
The 1457 code could also be a bad EVAP cannister solenioid. It's a part that sits on top of the EVAP cannister; it has a plug receptacle and a vacuum outlet on it. It costs about $55 at most parts stores. It can cause the check engine light to stay on. I had that light on for weeks. The new solenoid has been in my Civic for almost three weeks now, and so far, the light has stayed off.

this car come with tree diferent engines the answer i'm going to give you is for a 1.7 engine sohc that codes means you have a leak on the evaporative system this system monitor the vapors from fuel tank this code some time might appear for filling the fuel tank with car runing i recomend you to clear code and make sure the fuel cap is not loose because there is a fuel pressure sensor in the tank and if the sensor don't read the right pressure then it will set the code

code p1457 is an evap leak code. a honda dealer can run a functions test on the system with the honda daig scan tool. but 90% of the time the probelm is the CVS valve. also known as canister vent shut valve. i've seen this a hundred times. its located under the rear of the car on the drivers side. its bolted to the evap canister with 2 (most likely rusted out) bolts.- hope this helps
