Expect a savings of somewhere between $50 and $100 if you DIY the replacement.
#WHAT CAUSES MASS AIR FLOW SENSOR PROBLEMS PROFESSIONAL#
Keep in mind that the cost of the part makes up the vast majority of the professional repair costs, so doing it at home will only save you labor cost. The part is generally easily accessible and can be swapped out by an amateur mechanic. The good news is that replacing a MAF is not the most difficult home repair project you could undertake, so you’ll likely be able to do it yourself.

You may find a repair price tag of anywhere between $100 and $400, depending on the type of vehicle you own and where you take it to be fixed.

Other causes include excess vibration causing damage, a short or fault in the connections, or disconnected wiring. Dirt and road debris can get into the sensor, and sometimes moisture can cause degradation or corrosion. In all vehicles, however, a contaminated sensor is one of the most common causes of failure. This will again depend on the type of car you have. What Causes MAF Sensor Failure or Problems? There’s a lack of power or inconsistent power under acceleration.What Happens When a MAF Sensor Malfunctions?ĭepending on the make and model of the vehicle, a MAF sensor problem could cause a variety of issues. This all functions within the parameters of the vehicle’s specified air-fuel mixture to keep the engine running properly and efficiently. The change in air temperature around the wire, combined with a separate reading of the level of electricity needed to heat it, are used to determine the amount of fuel that needs to be injected. As more air flows around the wire, it cools, and requires more electricity to maintain a constant temperature. A separate sensor nearby monitors the air temperature as different levels of throttle are used. This type of MAF uses a wire that is heated with electricity. There are different kinds of MAF sensors, but in most cases today, the MAF is a hot wire-type sensor.
