The smog check should not have turned on your Honda Accords check engine light. We'd recommend calling the smog station and informing them of the situation. If the CEL doesn't turn off on its own after a few days, return to the smog station and ask them if they can use their scan tool to pull the trouble code(s) which caused the check engine light to illuminate. Or, you can visit the smog station without waiting a few days... up to you. We don't think the smog station should have a problem with pull the trouble codes from your Honda Accords computer.
