  • Can you clean a mass air flow sensor?

The MAF sensor works by heating a delicate platinum wire/plate and measuring the current required to keep it at a constant temperature while air blows past it.

After every single use, dust and oil particles stick to that hot wire/plate and make a layer on it and after sometime those particles start to insulate the wire/plate from the airstream that causes issues in the vehicle’s functioning.

But if you clean your car’s MAF sensor regularly, you can avoid the $300 repair charges and keep your engine running at top efficiency.
