Code P0102 2006 Nissan Altima Sedan Description

The Mass Air Flow (MAF) sensor is placed in the stream of the intake air. It measures the intake flow rate by measuring a part of the entire intake flow. It consists of a hot film that is supplied with electric current from the Engine Control Module (ECM). The ECM controls the temperature of the hot film by a certain amount. The heat generated by the hot film is reduced as the intake air flows around it. The more air, the greater the heat loss. Therefore, the ECM must supply more electric current to maintain the temperature of the hot film as air flow increases. The ECM detects the air flow by means of this current change. The Diagnostic Trouble Code (DTC) will be set when the ECM detects that the MAF Sensor Signal is less than the factory specifications.

Discuss the causes and fixes for P0102 2006 Nissan Altima Sedan OBDII Code

  • 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.

  • Yes, it's possible. Start by inspecting the Mass Air Flow (MAF) sensor. Clean MAF if possible.

  • Thank you very much. Your response prompted me to look for where the sensor actually was and learn how to clean it, more so, how to actually test if it is working properly or not.

  • Testing the MAF may require especial tools, but here is a video to clean the MAF.
