Details of the Scion p0101 OBD Code

Scion P0101 indicates an issue with the mass airflow sensor circuit performance.

OBD code P0101 for a Scion indicates an issue with the Mass Air Flow (MAF) sensor circuit.

This code is triggered by the Engine Control Module (ECM) when it detects that the MAF sensor is sending a signal that is out of the expected range.

The MAF sensor measures the amount of air entering the engine to help the ECM calculate the correct airfuel mixture for combustion.

If the MAF sensor is faulty or there is a problem with its circuit, it can lead to drivability issues and poor engine performance.
