P1257 is a VTEC system malfunction in my '98-'99 Accord list. Probably the same for yours?

I don't have a breakdown of the different VTEC codes at the moment, so it could be something like...
- low oil pressure
- bad VTEC oil pressure switch (or it's circuit)
- bad VTEC solenoid (or it's circuit)

AutoZone can read the code number OK, but sometimes their list of descriptions is kinda strange... I'm always suspicious of anything higher than P0999, since only the lower ones are the same for all makes of cars.
