Guys, I've been battling an issue with my MAF sensor and looking for any advise/ insight on this. The mass air flow sensor is part of the engine’s intake system and is located between the air filter box and the throttle valve.


Replacing a faulty Mass Air Flow Sensor is pretty complex and best left to a professional. Don't own a scanner? Visit your nearest Nissan service center. Connect an OBD-II scanner to the on-board computer in your Nissan to see if a Mass Air Flow Sensor error code is returned. Since a worn out Mass Air Flow Sensor can diminish engine performance, it can trigger the check engine light on your Nissan. If the engine is running lean, your Nissan might have trouble starting, or you may notice decreased performance or backfires when decelerating. If the Mass Air Flow Sensor is worn out or damaged, it can cause the engine to run lean, meaning there is too much air or not enough fuel in the air-to-fuel ratio.

Your Nissan's onboard computer takes in the information that the Mass Air Flow Sensor gathers and determines the amount of fuel that's necessary to keep the right ratio of air to fuel. The Mass Air Flow Sensor is positioned between the air filter and intake manifold on the engine and analyses how much air enters the engine through the engine's air filter. The Mass Air Flow Sensor on your vehicle is an essential part of the electronic fuel injection system.
