Code P0101 2010 Infiniti G37_sedan Description

The P0101 diagnostic trouble code (DTC) is defined as Mass Air Flow (MAF) Circuit Range/Performance issue. This means that the vehicle's engine control module (ECM) has detected a problem with the MAF sensor or its circuit. The MAF sensor is a crucial component that measures the amount of air entering the engine, allowing the ECM to determine the correct fuel-to-air ratio for optimal combustion.
