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. So, start working with those and see if you can get the 1457 code off of it.
I also looked around about the 1739 code as well which a transaxle error. However, I've found that there has been more than enough reported cases of problems of the such. Take a look at this link, and do a little reading.
I hope this helps you out.

First off, Hondas do not run MAF. If the car seems like it is driving better than before the light came on, it could be that the code just hasnt cleared yet. My 95 accord did the same after a fix, I just had to drive it to run the drive cycles.

start by removing the console. there should be four screws that hold it in; two on each side; one in the front and one in the rear. you may have to take the gearshift knob of if the car is manual trans.then, remove the ash tray. there are two screws at the front of the ashtray receiver and one at the back.with the ashtray and slide removed, take the bezel off of the radio. there should be two screws behind or above the air outlet vents on top andn two screws in the under the center dividing rail. you may have to pop out the air outlets to get to the screws. there may also be a screw at the bottom of the bezel in the center.with the bezel removed the only thing that holds the radio in at that point is two screws that come up from underneath where the ashtray receiver was. take out those two screws and the radio should pull out from the front. Be sure to disconnect the antenna lead and the connector from the back of the radio before pulling on it too hard or you'll damage one or the other.hope that helps

SOURCE: CHECK ENGINE LIGHT
you have a sensor on your transmission that tells that speedometer to work and well of course you already know the millage wont work because that speedometer sensor isnt working correctly, as far as the engine light i wouldnt think that that is linked to the speadometer, but have it checked. goodluck
