There is a leak in the EVAP Emission Control System Leak Detected (Control Canister System), many people advise that a loose gas cap is the reason. They are incorrect, loose gas caps produce P1456, EVAP Emission Control System Leak Detected (Fuel Tank System).
The P1457 typically means that you will need to have your vent shut valve on the canister under the car checked. Not something a casual weekend warrior can do. There are several checks that are done to narrow the problem, including vacuum leak tests and electrical tests. Pretty much a professional mechanic job.

An over- 65 weekend warrior certainly can replace the vent shut valve.* The hardest part was getting the car properly jacked and supported. I used the center jack point in the rear and two jack stands. For tools, you need 10mm and 12mm socket wrenches, vise-grip pliers, and a Phillips screwdriver. A 10-mm crowfoot or very short socket will be helpful. There are three bolts (10-mm head) that hold the canister to the car. There are two bolts (12-mm head) that hold a parking break cable bracket. Remove all 5 bolts. Undoing the parking brake cable bracket allows easier access to the canister. The rear-most bolt on the canister is under a cross brace. That is where the crowfoot or shortened socket comes in handy. After the bolts are removed, drop the canister down so you can access the two screws holding the shut valve in place. The screws are probably rusted. Use vise-grips (use ones with teeth on the jaws, if available) to grab the screws by the sides and get them started to turn. A little penetrating oil helped too. Of course, you need to disconnect the electrical connector, which is a typical pinch and pull connector, and the rubber connecting tube. Replace the new valve and reassemble. The valve does not come with the two mounting screws. My Honda dealer was kind enough to give them to me, including new washers.
*The correct name of the valve is as stated above. Autozone had no listing for the shut valve. It has the identical valve, same manufacturer and same Denso number, but calls it a bypass valve. I used the Honda part number and my local store was able to cross check it. The price difference was significant. John4153
