2012 nissan altima mass air flow sensor problems

Connect an OBD-II scanner to the on-board computer in your Nissan to see if the scanner returns a Mass Air Flow Sensor error code. Since a worn out Mass Air Flow Sensor can diminish engine performance, it may trigger your Nissan's check engine light. If the engine is running lean, you may notice decreased performance, backfires when decelerating, or your Nissan won't start. If your vehicle's Mass Air Flow Sensor is damaged or worn out, the engine may run lean, meaning there is too much air or not enough fuel in the air-to-fuel ratio.

Your Nissan's computer takes the information gathered from the Mass Air Flow Sensor and determines how much fuel is required to maintain the correct ratio of fuel to air. The Mass Air Flow Sensor sits between the engine's air filter and intake manifold and measures the amount of air that enters the engine through the engine air filter.

Your Nissan's Mass Air Flow Sensor is an important component of the electronic fuel injection system. Plays a vital role in your electronic fuel injection system.
