|P0101 2011 NISSAN SENTRA code tech notesBefore replacing the Mass Air Flow (MAF) sensor, try replacing the air filter and cleaning the MAF sensor with low compress air or MAF sensor cleaner. Reset code and drive vehicle. If the code comes back, it may be necessary to replace the MAF sensor.There is a factory service bulletin for the 2011-2012 Nissan Sentra:If the P0101 code is set and there are no drivability problems, the factory service bulletin suggests reprogramming the Engine Control Module (ECM) to repair the problem. Bulletin No. NTB12-051d.

|P0101 2011 NISSAN SENTRA code descriptionThe Mass Air Flow (MAF) sensor is placed in the stream of 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 temperature of the hot film is controlled by the ECM 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.
