Hi

You guy helped me so much previously when I my car door locks were not opening automatically and I managed to repair it myself. Thanks for that. This time I again need your help. I am getting this "Error code P1457 on Honda Civic 1999" passed few week. I changed my gas cap with a brand new one and for 2 day I did not see it, but now again it has come up. I checked the code too on the net and its a leak. Could you inform me what part would be faulty and what part to replace. Thank you in advance you professional people. Feel a pride to be on this site.

Thank you

Mathais Fernandes

MIL COMES ON WITH DTC P1457: EVAP BYPASS SOLENOID VALVE FAILURE TECHNICAL SERVICE BULLETIN

SYMPTOM
The MIL is on, and DTC P1457 [leak detected in EVAP control system (EVAP control canister system)] is set.
PROBABLE CAUSE
The EVAP bypass solenoid valve can fail due to corrosion. The solenoid valve may get water inside. If the water contains road salt, the solenoid windings could corrode, causing the valve to fail. In a few rare instances, the corrosion could be severe enough to cause an internal short in the solenoid valve, which could damage the ECM/PCM. If this happens, both the bypass solenoid valve and the ECM/PCM would need to be replaced.
Vehicles driven in the Northeastern part of the U.S. Are more likely to have this problem because of the salting of roads during the winter months. Vehicles driven where salt is not used on the roads are much less likely to have this problem.
