Code P0103 2006 Scion xB Description

The P0103 diagnostic trouble code (DTC) for a 2006 Scion xB indicates a problem with the Mass or Volume Air Flow Circuit High Input. This code is triggered when the Engine Control Module (ECM) detects that the signal from the Mass Air Flow (MAF) sensor is higher than expected, indicating a potential issue with the air flow entering the engine. The MAF sensor plays a crucial role in determining the amount of air entering the engine, which is essential for the proper air-fuel mixture required for combustion.
