The optimal air-fuel mixture leads to higher power output and ensures all the fuel gets used up. It has a “hot wire” which is heated to a constant temperature. The air flowing over it is trying to cool it down, and the exact volume of air can be measured by taking into account the electrical current necessary to heat the wire, with more airflow requiring a stronger current.įor modern fuel injection systems, precision is everything, and knowing how much air is available in every millisecond allows the ECU to adjust the fuel injection frequently. The mass airflow sensor measures the volume of air going into the throttle body. I strongly suggest that you read the following article as I’ll explain how the MAF sensor works, why it’s important and why you shouldn’t drive without it, even if the car is running better. If the car is running better with the MAF sensor unplugged, it means that the sensor is sending inaccurate readings and needs to be either cleaned or replaced. After unplugging it, the car seemingly runs better than it did with the MAF sensor. It is possible for the wires in the connector to break, causing the mass airflow sensor to not work.You’ve been trying to identify the cause of poor engine performance and your search lead you to the mass airflow sensor.

When doing this job, the mechanic may recommend changing the electrical connector that connects the mass airflow sensor to the car's computer system. If the vacuum hoses are leaking, it will give the same error code as mass airflow sensor failure. It is common for the mass airflow sensor to get dirty (if the air filter is dirty) and lose the ability to read the amount of air coming in the engine. If the sensor goes bad, the engine will not know the right amount of fuel to add, causing problems including poor gas mileage, lack of power and more. The computer in the car reads the amount of air coming into the engine from the mass airflow sensor and then calculates the correct amount of fuel needed for proper engine performance. For an engine to perform properly, it needs a specific amount of air-fuel mixture. The mass airflow sensor measures the amount of air entering the engine. All cars take air from the outside and pass it into the engine through the air filter. The mass airflow sensor is a round tunnel made of plastic with a sensor attached inside.
