Code P0103 2013 Toyota RAV4 Description

The P0103 diagnostic trouble code (DTC) for a 2013 Toyota RAV4 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 measures the amount of air entering the engine to determine the correct air-fuel mixture for combustion. When the MAF sensor sends a high input signal to the ECM, it can disrupt the engine's performance and fuel efficiency.
