When Your Chevy Malibu has P1101 trouble code stored, it means that the PCM detected a discrepancy with the voltage from the Mass airflow (MAF) sensor. It means that the (MAF) is out of self-test range.Check to see if the clamps to the sensor are tight. A slight leak of air around the sensor will make this code come up. Make sure the harness is connected and does not have any corrosion. If everything looks good, then the MAF sensor needs to be replaced. A bad MAF sensor can cause various driveability problems, including a no-start, stalling, lack of power, and poor acceleration.
