Code P0102 2006 Nissan Altima Sedan Description

The diagnostic trouble code P0102 for a 2006 Nissan Altima Sedan indicates a problem with the Mass or Volume Air Flow Circuit, specifically a low input signal being detected. The Mass Air Flow (MAF) sensor is a crucial component of the vehicle's engine management system, responsible for measuring the amount of air entering the engine to determine the correct air-fuel mixture for combustion. When the MAF sensor detects a lower than normal input signal, it can lead to various performance issues and potential long-term effects if not addressed promptly.

  • I started receiving this code after I temporarily removed the air filter. It may have happened because I turned the ignition to the On position (without actually starting the car) while the filter was off.
