Code 1457 i would like to replace my solenoid/valve that i think is causing my 1457 code but not sure which part it is under my honda could someone guide me to it or direct me to it by part number

If the code is back that problem that the PCM detected is still ongoing. Please watch the Youtube video at the link.

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

Before you replace these critical components, have you replaced the fuel/gas cap first?

oxygen sensor

1457 is a leak in the charcoal canister or its plumbing system. my money says its in your plumbing. clogged/disconnected lines.

really though, the 1457, could be anything in your evap emmissions system. canister purge solenoid, 2 way bypass valve, fuel tank pressure sensor, canister vent shut valve, alot of rubber hoses, alot of hard plastic lines, evap canister, etc,etc,ect,etc.blah, blah,blah.

a good DIGITAL multimeter and vacuum pump will ease your pinpointing.

im not sure if haynes or helms carry the info on troubleshooting this problem, but, if they do, it'll be good as a reference map.

PS: my problem was with the two way valve.

This is a common problem with these and a few other Honda cars.

The code means "Evap Bypass Solenoid Valve Failure"

The solution is to replace a few parts dealing with the EVAP system.

You can call your local Honda dealer, as there is a TSB (technical service bulletin) on this problem, and it may be covered under warranty.

The TSB number to give them is 03-001.

sounds like you have a leak in EVAP system need to have tested to find leak they make a smoke machine to test

there are five thing to check
1. Gas Cap if it does not seal you will get this code
2. canister vent shut off value under the hood right side (2 wire) one with green/white wire going to it
3. 2 way value right side of the gas tank
4. vent pressure senser near the gas tank
5. bypass solenoind next to the 2 way value
