Code P010D 2009 Infiniti G37_sedan Description

The P010D code for a 2009 Infiniti G37 sedan indicates a problem with the Mass Air Flow (MAF) Sensor in Bank 2, specifically a high input circuit. The MAF sensor is a critical component of the vehicle's engine management system, as it measures the amount of air entering the engine to ensure the correct air-fuel mixture for combustion. When the MAF sensor detects a high input signal in Bank 2, it means that the airflow reading is higher than expected, which can lead to various performance issues.
