P1457 code in 2001 Civic LX

[Chris Meutsch]

It popped up on Thursday. I have an Actron codescanner and erased the code/light. Hasn't come back. My shop manual says it's part of the EVAP system. It also says it's a two-trigger code, which I guess means it needs to happen twice before the light comes on.
Since it hasn't come back in four starts now, could it have been a one-time problem? I took off/put back on the gas cap after clearing the code.
Anyone else have this problem with a Honda?

A quick google suggested that's the "Evap leak" code, right? If so then it's possible the gas cap just wasn't on tight enough. If it doesn't come back I wouldn't worry about it. Just make sure to put the cap on until it clicks several times when you fill up.
