Use a scan tool to erase the old codes.

You can either clear the computer (PCM) with a scan tool or code reader or drive normally for a few days with the gas tank between 3/4 and 1/4 full. If you fixed the problem successfully the light will go out on it's own. But mind the gas tank level. The PCM won't run all the diagnostics unless the tank is within those parameters. HTH. -Jim
