20201007· Several sensors and actuators come into play, such as the mass air fuel (MAF) sensor and fuel injectors, and just as with any other car part, these sensors and actuators can degrade over time. If your vehicle is having performance issues, you may be experiencing one of the symptoms of a bad mass air flow sensor. What Is a Mass Air Flow Sensor?
20210222· What does Mass Air Flow Sensor do? Before going into detail on what will happen when you disconnect the mass airflow sensor it is important to understand what it actually does. If you want a technical definition of how a mass airflow sensor works, then you can take a look at the article we have here , but for this article, we will just cover the basic function of the mass airflow sensor.
20210718· Mass Air Flow Sensor Replacement. A mass air flow sensor can cost anything from 80 to 380 to replace. The cost of the part alone ranges from 30 to 300 for typical aftermarket mass air flow sensors at the lower end of the range, while higher quality or more sophisticated OEM sensors are more expensive. If you hire a professional to replace it, you may expect to pay between 50 and 80 …
20090318· Joined Jan 21, 2006. ·. 10,030 Posts. 2 · Mar 10, 2009 (Edited) Some go bad based on an air filter that is the oiled type. Sometimes a person over oils them and it covers the sensor. As for normally filter and wear and tear it may be just one of those things. Cant say anything on normal use and life of a MAF on stock setup.
