P1457= EVAP control system leak detected
Canister vent shut off valve is a known troublemaker.
I personally wouldn't run out and buy an O2 sensor to try to diagnose the problem.

You have an EVAP leak. Check your gas cap also. Do not replace your O2 sensor it will not fix that problem.
What year accord is it? If its an older model that canister may have come apart spreading the charcole material into the system

Re: P1457 code
The canister vent shut valve or the EVAP Bypass Solenoid Valve could be the problem, as the culprits easily get corroded in geographic locations that use a lot of salt on the roads in the winter. Honda had to redisign the parts to address this problem.
TSB's ( Technical Service Bulletin's ) 01-011 ( EVAP Control Canister Vent Shut Valve 98-99 models ) and 03-001 ( EVAP Bypass Solenoid Valve 98-02 - depending on the model ) address these problems and explain that if left unchecked could damage the PCM ( computer module ). It has nothing to do with the gas cap as that would be a P1456 code.
If the car is a 97 Honda, the warranty on the emissions system has been extended to 10 years or 150,000 miles. See TSB 98-081 (97 only ).
The EVAP Control Canister Vent Shut Valve is easy to find and replace youself. And if your lucky and can persuade the Dealer to fix it, they can replace it using goodwill ( free ). They don't do it always, but it can't hurt to ask. This is also mentioned in the TSB's.
But if you want to do it yourself, and it may take less time than bugging them, and is fairly simple. Just be careful of the two screws that hold it ( EVAP Control Canister Vent Shut Valve ) in place as they are probobly badly corroded. Spray them with some break free, if they give you a hard time, rather than taking the chance at snapping them. But you won't know till you look at them, they may just come right out, but i just wanted to warn you. The bottom of the car get abused by all the rain and salt it is exposed to over the years.
I have all the TSB's as well as EVAP/ fuel system diagrams, if anyone needs them just contact me. The TSB's have good diagrams as well and show you a lot of detail.
A link to a previous thread that wrote somewhere else that contains a slew of information about this.
