P0101
Mass Air Flow Circuit Range/Performance
The P0101 code indicates that the Mass Air Flow (MAF) sensor is providing data that falls outside the expected range for current engine operations. Since the MAF sensor determines the amount of air entering the engine to calculate fuel delivery, incorrect data leads to a poor air-fuel ratio, causing hesitation and rough running.
