P0101 — Mass or Volume Air Flow Circuit Range/Performance

Powertrain (motor/växellåda)

This code indicates that the Powertrain Control Module (PCM) has detected a performance problem with the Mass Air Flow (MAF) sensor or its circuit. It suggests that the MAF sensor's output signal is implausible or inconsistent compared to other engine operating parameters.

The MAF sensor measures the amount of air entering the engine, which is crucial for the PCM to calculate the correct fuel injection and ignition timing. This DTC monitors the rationality of that measurement.
