What does code P1144 mean?

Q: What does code P1144 mean?

Mass Or Volume Air Flow Circuit Open/Short To Ground. P1144 on Volkswagen vehicles indicates that the engine control module has detected an open circuit or a short to ground in the mass air flow (MAF) sensor circuit. The MAF sensor measures the volume of air entering the engine, and this fault means the sensor's signal wire is either broken or touching ground, preventing the ECM from receiving a valid air flow reading.
