Code P0103 2016 Toyota RAV4 Description
The P0103 diagnostic trouble code (DTC) for a 2016 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 that the signal from the mass air flow sensor is higher than expected. The mass air flow sensor measures the amount of air entering the engine, which is crucial for the proper air-fuel mixture to be delivered for combustion. When the ECM receives a high input signal from the sensor, it can lead to a variety of performance issues.
