1998 Infinity QX4 - OBD2 Code P0100: Mass Air Flow Sensor Issue Explained
My 1998 Infinity QX4 is showing an OBD2 diagnostic code P0100. What does this mean, and what should I do about it? The error refers to the Mass Air Flow (MAF) sensor, which measures the amount of air entering the engine. This code indicates a problem with the MAF sensor or its circuit, potentially leading to poor fuel efficiency, stalling, or rough idling. Since I'm not familiar with automotive terms like 'MAF,' I'd appreciate clear guidance on troubleshooting steps and whether any recent repairs or maintenance might have triggered this issue.
