How long do i have to drive before my check engine light turns off?

replaced a mass flow air sensor in my 07 honda accord after check engine light came on. The engine light remained on after i replaced the part. Auto zone told me i would have to drive 60-70 miles in order for the computer to reset itself and clear the code causing the engine light to be on. I drove the 70 miles since and the light remains on. Any thoughts or info would be helpful.
