C230 Check Engine light stays on

The Check Engine light on my 1997 C230 came on, so I took it to the dealer, who performed some tests and recommended that I change the air mass flow meter. They "think" this will solve the problem.
My questions are:
What other failures could cause the Check Engine light to stay on?
How can I be certain that the air mass flow meter is in fact defective?
