Fault code P010E is a generic OBD-II diagnostic trouble code defined as “Mass or Volume Air Flow Sensor B Circuit Intermittent/Erratic.” This indicates that the vehicle’s Powertrain Control Module (PCM) has detected an unstable, fluctuating, or sporadic signal from the secondary circuit (“Circuit B”) of the Mass Air Flow (MAF) sensor. Unlike hard circuit faults (low or high), an intermittent fault means the signal is unstable, dropping out, or spiking unpredictably .

Fault code P010D is a generic OBD-II diagnostic trouble code defined as “Mass or Volume Air Flow Sensor B Circuit High Input.” This indicates that the vehicle’s Powertrain Control Module (PCM) has detected that the voltage or frequency signal from the secondary circuit (“Circuit B”) of the Mass Air Flow (MAF) sensor is consistently above the expected normal operating range for a specified period .

Fault code P010C , applicable to all vehicle manufacturers , indicates ” Mass or Volume Air Flow ‘ B ‘ Circuit Low ” .

Fault code P010B, applicable to all vehicle manufacturers, indicates “Mass or Volume Air Flow Sensor B Circuit Range/Performance” .

Fault code P010A, applicable to all vehicle manufacturers, indicates “Mass or Volume Air Flow ‘B’ Circuit Malfunction” .

Fault code P0101, applicable to all vehicle manufacturers, indicates “Mass or Volume Air Flow A Circuit Range/Performance” . This generic powertrain code signifies that the Powertrain Control Module (PCM) or Engine Control Module (ECM) has detected that the signal from the Mass Air Flow (MAF) sensor is outside the expected range or is performing incorrectly .
