P0102 code on 2003 Pontiac Bonneville

The code P0102 keeps comeing up I checked the mass flow sensor and it is good also changed the vacum lines can you tell me you to make it stay out or fix the problem thanks.

Asked by for the 2003 Pontiac Bonneville
I agree with bob.
How did you check the mass air flow??? how did you determine it was good??
make sure that the fuse for 12v power is there. the sensor is the most common failure for this code.

If that's the only code you're getting, it sounds like the airflow (MAF) sensor is failing and out of calibration, or that there's an air leak into the intake system between the MAF and the throttle body. It also could possibly be caused by MAF sensor contamination or a faulty electrical connection.
