Code P0102 2005 Infiniti G35 Description

The P0102 code on a 2005 Infiniti G35 indicates a problem with the mass or volume air flow circuit, specifically a low input signal. This code is triggered when the Engine Control Module (ECM) detects that the signal from the mass air flow sensor is lower than expected. The mass air flow sensor measures the amount of air entering the engine, which is crucial for determining the correct air-fuel mixture for combustion. A low input signal can lead to issues with fuel efficiency, engine performance, and emissions levels.
