The air mass flow sensor is a round plastic tunnel with a sensor connected inside. All cars take air from outside and pass it to the engine through the air filter. The air mass flow sensor measures the amount of air entering the engine. For an engine to function properly, it needs a specific amount of fuel and air mixture. The car computer reads the amount of air entering the engine from the air mass flow sensor, and then calculates the correct amount of fuel required for proper engine performance. If the sensor fails, the engine will not know the correct amount of fuel to add, which will cause problems like low fuel consumption and lack of power.
It is common for the air mass flow sensor to become dirty and lose the ability to read the amount of air entering the engine. If the suction hoses are leaking, it will give the same error code as the failure of the air mass flow sensor. While doing this work, the mechanic may recommend changing the electrical connector that connects the air mass flow sensor to the car's computer system. The wires in the connector may break, preventing the air mass flow sensor from working.
Regularly changing your air filter can improve the life of your air mass flow sensor. Mass air flow sensors often stop working due to faulty connectors or wire harnesses.When replacing the air mass flow sensor, the air passage between the sensor and the intake manifold must be inspected.
Mechanic should always inspect the suction hoses and breather tube connected to the air mass flow sensor when replacing it. These items may be leaking. Replacing the sensor without repairing the leaks will not solve the problem.
Yes. It does not stop you from driving your car but you will get poor fuel economy and car will remain in limp mode while driving with the EML light on. To function optimally, your vehicle must have the perfect fuel and air ratio. As with the faulty or failed MAF sensor the less amount of air enters the throttle body and travels to the intake manifold. As such, the fuel must be adjusted to be optimal for the amount of air. The air mass flow sensor measures the mass of air entering the vehicle and sends the information to the management system of the car's computer. This system controls the amount of fuel injected into the cylinders, so that the ideal fuel and air ratio is achieved. When the air mass flow sensor stops working, the computer cannot receive information about the air intake and the fuel and air ratio will be incorrect. This will cause your engine to malfunction and sometimes it will not work at all.
