Timing belt replaced now I have a check engine light

What is your question?

I had the timing belt replaced and water pump. Left the dealership no lights on the dash. Next morning I started up the car sounded fine but the check engine light came on. What should I suspect is the problem. Is it likely that a sensor was damaged or disconnected when the timing belt was put on? I'm just waiting for a song and dance from the car dealership

How long has your 1998 Honda Accord had this problem?
