Code P0102 2017 Toyota RAV4 Description

The P0102 diagnostic trouble code (DTC) for the 2017 Toyota RAV4 indicates a problem with the Mass or Volume Air Flow Circuit, specifically a low input signal. The Mass Air Flow (MAF) sensor plays a crucial role in the engine's performance by measuring the amount of air entering the engine to determine the appropriate fuel mixture for combustion. When the MAF sensor detects a low input signal, it means that there is insufficient airflow entering the engine, leading to potential issues with fuel delivery and combustion efficiency.
