Cool Check Engine Light is on. Help!

My check engine light came on two days ago. I own a 1997 S 320. I checked under the bonnet and found one of the white vacuum lines...the one behind the fan belt broken. least 6 to 8 inches were missing as though it was snapped off.
I rushed to Auto Zone and purchased a rubber hose to reattach the white lines.
Here's the long, if that was the issue, will it take for he check engine light to go out.

Thanks in advance.........rick (

Do you think we are mind readers? You don't even mention what you car you have.

If you fixed the problem the check engine light will go off after a few on/off cycles of the car.
