I have replaced the mass air flow sensor and the code keeps coming on. It only stayed off for a month. It causes the car to idle rough. I am not sure if the other problems that are happening are related but the only light that comes on is the service engine light and the code shows p0101.
Service engine light remains on. Code po101. Mass air flow. Changed the air filter, and the maf sensor but light remains on bulentin ntb12-051d regarding this issue states should get the engine control module reprogramed. I think it should be nissian recall and they should cover it.
