Contaminated or failed mass air flow sensors cannot measure the amount of air flow correctly.
As a result, Failed mass air flow sensors can cause a variety of driveability problems, including a no-start, stalling, lack of power, poor acceleration. In other cases, a car may have poor gas mileage and black smoke from exhaust.
Dirt, Dust, Moisture and Oil are all bad for sensors.
This causes the engine computer to miscalculate the amount of fuel to be injected.
Also, This accumulation cause the mass air flow sensor (MAF) to read incorrectly. As a result, Corrupting the fuel-air ratio calculations of the ECU.
Incorrect readings can cause the engine to run too rich or lean depending on the readings.

Finally, Hot-wire mass air flow sensor (MAF) have a small electrically heated wire (hot wire) and a small temperature sensor installed close to the hot wire.
