fuel vapor generated when refueling in the EVAP canister.The EVAP control system leak detection method improves the accuracy and frequency of the detection by determining faulty components and vapor leakage for each part. The EVAP control system (from the purge valve to the fuel tank) is divided into two parts. One is the "EVAP Canister Side" (from the EVAP two way valve to the purge valve) and the other is the "Tank Side" (from the EVAP two way valve to the fuel tank). There is 0.04 inch leak detection and 0.02 inch leak detection. If the 0.04 inch leak detection results are OK, the 0.02 inch leak detection runs.

handy OBD2 scanner said P1457, the evap system. I cleared the code, reset the CEL, filled the tank, and made sure the gas cap was tight. Well, after about 30 miles the light is back on with the same code. I called the local Honda dealership hoping there's a TSB about this problem, no such luck. The service guy said it's not likely to be the gas cap if the CEL light came back on so fast and I made sure the cap is tight. As a test, I put a different gas cap on and I'll see if the code comes back. I'll post any findings. In the meantime, has anyone else run into this problem? If so, how was it corrected? Thanks, John sohcfreak9703-01-2005, 01:40 PMis it a leak code, or evap flow? just pull off the lines and check for build up, and if its a leak...smoke test it.. johnb16a203-01-2005, 09:38 PMThanks for your reply. The manual says: "The scan tool indicates Diagnostic Trouble Code (DTC) P1457: Evaporative Emission (EVAP) control system leak detected (EVAP control cansiter system)" I haven't had a chance to investigate the problem beyond fiddling with the gas cap. The weather has just been too lousy. I have the manual and plan to try to fix it soon. Not sure how to perform the tests you mentioned, please clarify. Thanks again, John superbluecivicsi03-02-2005, 02:56 AM1457 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. [qoute] smoke test it.. [qoute] i have not heard this terminology before..............enlighten me ;) johnb16a203-02-2005, 09:12 AMThanks for your reply. I have the Helms manual, a digital meter, and a newly acquired vacuum pump. I just have to wait for
