Code P1101 Buick Description

The Mass Air Flow (MAF) Sensor is integrated with the Intake Air Temperature (IAT) sensor. The MAF sensor is an air flow meter that measures the amount of air entering the engine. The MAF sensor used on this engine is a voltage-based sensor. The greater the airflow, the greater the voltage signal. The Engine Control Module (ECM) uses the MAF sensor signal to provide the correct fuel delivery for all engine speeds and loads. The Diagnostic Trouble Code (DTC) will be set if the ECM detects that the measured MAF is not within a calibrated range of the model for greater than 2 seconds.
