If your MAF sensor is consistently reporting inaccurate information to your car’s computer (for example, due to deformation of the wire, or damage to the electrical equipment), then your engine will either consistently run lean or rich. Your Engine Consistently Runs Lean or Rich Common signs of a failing MAF sensor include: 1. Your car uses this number for multiple calculations, which is why keeping your MAF sensor running properly is important. This type of sensor measures the amount of current necessary to maintain the temperature of a wire above 90 degrees, which in turn gives your car’s computer a measure of the mass of the air entering the engine. This is important as it allows your engine to regulate its performance and change the intake of air to keep your engine running in its best condition.īy far, the most common type of MAF sensor is a “hot-wire” MAF sensor. Check out the What This Fits tab for more information.Your Mass Air Flow Sensor (MAF Sensor) is a piece of technology within your engine which tells your car’s computer how much air is entering the engine. This Mass Air Flow Sensor 22680CA000 fits your Nissan 350Z, Nissan Altima, Nissan Maxima, Nissan Murano, Nissan Pathfinder, Nissan Quest, or Nissan Sentra. When it's time to replace your old Mass Air Flow Sensor, ensure you get the right part with a genuine Mass Air Flow Sensor from Nissan Parts. Using a specialized Mass Air Flow Sensor cleaner, they'll get rid of grim, debris, or dirt that has collected on the sensor. 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. Replacing an old or worn out Mass Air Flow Sensor is difficult and should be left to a professional. Don't have a scanner? Head to your closest Nissan service center for assistance. 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. Since an old Mass Air Flow Sensor can affect engine performance, it can cause the check engine light to illuminate on your Nissan dashboard. If your Nissan's 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, it can cause the engine to run lean, meaning there is too much air or not enough fuel in the air-to-fuel ratio. 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. 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 Mass Air Flow Sensor on your Nissan is an essential part of the electronic fuel injection system. Plays a vital role in your electronic fuel injection system.
