The check engine light came on 3 times in our 99 Accord LX in the last month. First it was just the gas cap, then the evap canister and other parts were replaced and my mechanic thinks it's the PCM. This was his computer readout - code P1457. I then took it to the Honda dealer twice, once they said it was code P1457 but really P1456 (they replaced the evapconstant
shut valve and a new gas cap, although the car had a new after market gas cap) and a secondary code P0420 (catalytic converter below threshold), saying the catalytic converter needed replacing and the second time it was code P1457 - large evap leak - removed gas cap and reinstalled - system OK,
but still a secondary code P0420. I had the catalytic converter replaced by my local mechanic Monday and the check engine light came on again today (code P1457). AZ said it was the same code. All parts of the evap system have now been replaced. Where do I go from here? Is it the PCM?
