P0101 is triggered by the car's engine control unit when the mass air flow (MAF) sensor signals are outside of the normal operating range. This indicates that there is a problem with the sensor circuit or engine performance. The MAF device is used to measure the volume and density of the air that’s entering the engine. This information is used to ensure that the engine works at optimum efficiency.
