Code P0100 2006 Toyota Prius Description

The P0100 code for a 2006 Toyota Prius indicates a problem with the Mass or Volume Air Flow Circuit. This code is typically triggered when the Engine Control Module (ECM) detects that the air flow sensor is providing inconsistent or incorrect readings. The Mass Air Flow (MAF) sensor plays a crucial role in the engine's operation by measuring the amount of air entering the engine, which is essential for determining the correct fuel to air ratio for combustion. When the MAF sensor malfunctions, it can lead to a variety of performance issues, including reduced fuel efficiency, rough idling, stalling, and even engine misfires.
