Can a bad air sensor cause a car to backfire?

Bad air sensor results in car backfiring. Each car has an on-board computer which inspects and collects data on the air entering the engine constantly. All this process is done through the mass air flow sensor. The on-board computer will get the incorrect readings if there are some problems with the sensor, which will happen when the sensor cokes.
