***This is a common problem with Accords, especially ones that is driven around the snow-belt area. The EVAP system can often corrode causing the check engine light to go on. As your vehicle has out of warranty for a long time, I highly doubt that the warranty appies to you, but hey, it doesn't hurt to ask. It is a well-known defect/malfunction. You have to order the parts from Honda anyway (no aftermarket parts store carries the part). I included a partial description of the Technical Service Bulletin provided by Honda.***
MIL COMES ON WITH DTC P1457
TECHNICAL SERVICE BULLETIN
Reference Number(s): 01-011, Date of Issue: June 26, 2001

ARTICLE BEGINNING
SYMPTOM
The MIL is on, and DTC P1457 [leak detected in EVAP control system (EVAP control canister system)] is set.
PROBABLE CAUSES
The symptom could be the result of any of these causes:
An EVAP system component fails.
The PCM does a diagnostic test on the EVAP system before the primary heated oxygen sensor
(HO2S) is active. If this happens on two consecutive driving cycles, the MIL comes on and DTC P1457 falsely sets.
The EVAP system depends on operation of the EVAP control canister vent shut valve for the
diagnostic self-test. If the valve does not function properly, the MIL comes on and DTC P1457
sets. This condition can occur with vehicles normally driven in any of the states listed in the "Applies To" heading. Failure of this components does not affect the performance of the EVAP system.
