Check engine light code P1457, Vent Shut Valve

Does anyone have a diagram of where the vent shut valve ( Gas Tank ) is located on a 98 honda Accord LX. I see that this topic was visited in Aug of 03 or 04 and I saw that noone responded to the location of the valve. I have the same problem with the above DTC code. Had the code reset once and it is reapearing. Also replaced the gas cap and that didn't fix it either. And from what I read in the old thread, the fact that it is winter and very salty on the roads leads me to think that this is definately the problem. Lastly, does anyone have a Helms manual for a 98 Accord that they want to get rid of? Thx in advance.....

The valve is on the side of the charcoal canister. It has a big 1/2 inch rubber hose on it and has a 2 pin brown connector. Its held in place by 2 phillip screws
