Code P1144 Audi Description

The P1144 code for Audi indicates a problem with the Mass Air Flow (MAF) Sensor, specifically an open circuit or a short to ground. The MAF sensor plays a crucial role in measuring the amount of air entering the engine, which is essential for the proper functioning of the fuel injection system. When the MAF sensor is not functioning correctly due to an open circuit or short to ground, it can lead to inaccurate air flow measurements, resulting in poor engine performance, reduced fuel efficiency, and increased emissions.
