A MAF sensor diagnostic trouble code ( DTC) stored in your vehicle computer' s memory. P0100: Mass Air Flow ( MAF) Sensor Circuit Malfunction. P0101: Mass Air Flow ( MAF) Sensor Circuit Range/ Performance Problem. a technical explanation: Basically this P0101 diagnostic trouble code ( DTC) means that there is a problem with the Mass Air Flow ( MAF) sensor or circuit.
