- 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 Nissan is an essential part of the electronic fuel injection system. The Mass Air Flow Sensor is positioned between the engine's intake manifold and the air filter and measures the amount of air that enters the engine through the engine air filter. The computer in your Nissan takes the information gathered from the Mass Air Flow Sensor and regulates how much fuel is needed to maintain the proper air to fuel ratio.
If your vehicle's Mass Air Flow Sensor is damaged or worn out, it can cause the engine to run lean, meaning there is too much air or not enough fuel in the air-to-fuel ratio. If your Nissan's engine is running lean, you may notice decreased performance, backfires when decelerating, or your Nissan won't start.
Since an old Mass Air Flow Sensor can affect engine performance, it can cause the check engine light to illuminate on your Nissan dashboard. Using an OBD-II scanner, connect to your Nissan's computer and check the codes to see if the scanner returns a Mass Air Flow Sensor error code. Don't have a scanner? Head to your closest Nissan 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 Nissan technician may be able to fix the sensor's issue by cleaning the sensor as opposed to replacing it. Using a specialized Mass Air Flow Sensor cleaner, they'll get rid of grim, debris, or dirt that has collected on the sensor.
