Any real Chevy mechanics on this board?

2006 Chevy 2500HD - 6.0 - Automatic - low miles.

When I bought this truck the dealer had just replaced the code P1101 - Mass Airflow sensor.

Check engine light was out and everything seemed fine.

Now, the check engine light comes on every time I drive it.

I replaced the sensor one more time and the light still comes on every trip.

Ideas?

Thanks
