Got "check engine light" on for 99 civic. What does P1457 mean?

Was told the code was P1457 at AutoZone. What does it particularly mean for a 99 Civic? Thanks.

An improperly tightened fuel tank cap is often the cause. Remove, then install and tighten per the owner's manual (three clicks?), and the code may go away. Check your owner's manul for resetting the CEL.
