- 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 important component of the electronic fuel injection system. The Mass Air Flow Sensor sits between the air filter and intake manifold on the engine and measures the amount of air that enters the engine through the engine air filter. 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.
If your vehicle's Mass Air Flow Sensor is damaged or worn out, it can cause the engine to run lean, meaning the air-to-fuel ratio either has too much air or not enough fuel. If your Nissan's engine is running lean, your Nissan might have trouble starting, or you may notice decreased performance or backfires when decelerating.
Since engine performance can be affected by an old Mass Air Flow Sensor, it may trigger your Nissan's check engine light. Using an OBD-II scanner, connect to your Nissan's computer and check the codes to see if there's an error code for the Mass Air Flow Sensor. Don't own a scanner? Head to your closest Nissan service center for assistance.
Installing a new Mass Air Flow Sensor is complicated and should be left to a trained technician. If you have your air flow sensor issues professionally inspected, the technician may be able to resolve the sensor's issues with a sensor cleaning instead of a replacement. They'll use a specialized mass air flow sensor cleaner to remove any dirt, debris, or grime that's built up on the sensor.
