What does code P010B mean?

Q: What does code P010B mean?

Mass or Volume Air Flow Sensor B Circuit Range/Performance. P010B indicates that the powertrain control module has detected a range or performance fault in the signal from the 'B' mass or volume air flow sensor circuit, which is often the second sensor in a dual-intake or redundant air-metering arrangement. The computer compares the sensor's reported airflow against expected values derived from throttle position, engine speed, and manifold pressure, and it sets this code when the signal falls outside the acceptable range or behaves erratically.
