• Monitors air levels within your engine
• Plays a vital role in your electronic fuel injection system
• Replacement can be complex

The Mass Air Flow Sensor on your INFINITI performs an essential function in the electronic fuel injection system. The Mass Air Flow Sensor is positioned 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 INFINITI's computer takes the information gathered from the Mass Air Flow Sensor and determines the amount of fuel that's necessary to maintain the proper air to fuel ratio.

If the Mass Air Flow Sensor is worn out or damaged, the engine may run lean or rich, which means either too little fuel or too much air is in the air-to-fuel ratio. If the engine in your INFINITI starts running lean, you might notice symptoms such as backfires when decelerating, decreased performance, or your INFINITI won't start.

Since a worn out Mass Air Flow Sensor can diminish engine performance, it can cause the check engine light to illuminate on your INFINITI dashboard. Connect an OBD-II scanner to the on-board computer in your INFINITI to see if the scanner returns a Mass Air Flow Sensor error code. Don't have a scanner? Head to your closest INFINITI service center for assistance.

Replacing an old or worn out Mass Air Flow Sensor is difficult and should be left to a professional. If you receive a professional inspection for air flow sensor issues, your technician might be able to solve them by cleaning the sensor as opposed to replacing it. They will use a specific type of Mass Air Flow Sensor cleaner to get rid of grim, debris, or dirt that has collected on the sensor.
