Code P0103 2006 Toyota Camry Description

The P0103 diagnostic trouble code (DTC) for a 2006 Toyota Camry indicates a problem with the Mass or Volume Air Flow Circuit High Input. This code is triggered when the engine control module (ECM) detects a higher than normal voltage from the Mass Air Flow (MAF) sensor. The MAF sensor is responsible for measuring the amount of air entering the engine, which is crucial for the proper air-fuel mixture needed for combustion. When the ECM receives a high input signal from the MAF sensor, it can lead to a variety of performance issues in the vehicle.
