Code P1144 Volkswagen Description

The P1144 diagnostic trouble code (DTC) for Volkswagen vehicles indicates a problem with the Mass Air Flow (MAF) sensor being open or shorted to ground. The MAF sensor is a crucial component of the engine management system, measuring the amount of air entering the engine to ensure the correct air-fuel mixture for combustion. An open or shorted MAF sensor to ground can lead to incorrect readings or a complete failure of the sensor, resulting in poor engine performance and fuel economy.
