I was wrong with my first post.

Reading over the DTC troubleshooting chart (Honda manual) you really will need to leave this to a good technitian with the proper tools.

Tighten the gas cap as much as you can, the code will still come.

good luck from here

I had p1457 when the car was new, it required replacement of parts, it was most definitely not a loose gas cap.
