The reduced air flow will affect the sensor’s ability to accurately read air levels in the engine, leading to problems with engine performance. Over time, contaminants such as carbon will find their way into the mass airflow sensor, creating a buildup which makes it harder for air to pass through. Generally, you should get at least ten years of driving out of your mass airflow sensor, but this can vary depending on several factors. For this reason, the sensor is generally not replaced until it fails.

In fact, they have no scheduled replacement interval. Mass air flow sensors are designed to last the lifetime of your vehicle. How long does the mass airflow sensor last? Learn more about how the mass airflow sensor works
