"A very common late 90’s code, P1457 is a failure in one of the evap system solenoid valves. There are 2 culprits, the Vent Control Valve & the 2 Way Bypass Valve. They short out due to corrosion/contamination from water seeping into the valves. Of the two, the real culprit seems to be the 2 Way bypass Valve. I would also have the Gas (fuel) filler Cap checked. The P1457 can be also set by a loose / defective gas cap as well.
As far as the Honda “Good Will” consideration; It won’t hurt to ask.
