Hi and thanks for contacting Your Mechanic. The code P1101 means that the mass airflow sensor (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. Check the harness and see if the contacts are corrosion free. If everything looks good, then the MAF needs replaced. If you need further assistance with the mass airflow sensor replacement, then seek out a professional, such as one from Your Mechanic, to help you.
