Code P010D 2012 Infiniti G37_sedan Description

The P010D diagnostic trouble code (DTC) specifically pertains to the Mass Air Flow (MAF) sensor in Bank 2 of a 2012 Infiniti G37 sedan. This code indicates that the MAF sensor is detecting a high input signal from Bank 2, which can lead to various performance issues in the vehicle. The MAF sensor plays a crucial role in measuring the amount of air entering the engine, allowing the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. When the MAF sensor in Bank 2 detects a high input signal, it means that the airflow reading is higher than expected, which can result in a rich air-fuel mixture.
