P0102 — Mass or Volume Air Flow Circuit Low Input

Powertrain (motor/växellåda)

This code signifies that the Powertrain Control Module (PCM) has detected a low input signal from the Mass Air Flow (MAF) sensor. This typically means the voltage signal from the MAF sensor is lower than expected for current engine operating conditions.

The MAF sensor measures the amount of air entering the engine, which is critical for fuel mixture calculations. This DTC specifically monitors for an abnormally low signal, indicating either insufficient air measurement or a sensor/circuit issue.
