Mass Air Flow Sensor Replacement Cost
Mass airflow sensors (MAF) are often replaced when the only problem is a bad connector or the sensor wiring harness. The shop should check these items before replacing the sensor.
High-performance style wet foam air filters are not recommended because they will damage the mass airflow sensor and actually cause poor performance.
A failing mass airflow sensor can cause the Check Engine Light to come on and engine starting/running problems.
If the mass airflow sensor (MAF) is not functioning correctly, the vehicle may lack power when accelerating or going up hills.
