This can result in critical car problems. In the case of a bad mass air flow sensor, the fuel injection is not correctly calculated by the engine control model or ECM. This measurement is important to estimate how much fuel is required for the ideal air-fuel ratio (AFR). What is a MAF Sensor?Ī mass air flow (MAF) sensor is a car part that measures the quantity of air mass flow into an engine’s inlet. There are a few symptoms to identify a bad MAF sensor and replace it in time. However, with time and usage, these sensors might degrade. To achieve that, several sensors are assembled including fuel injectors, camshaft position sensors and mass air fuel sensors or MAF.

When you increase the diameter of the piping, you allow more air to flow over the 0-5 volt MAF sensor without overwhelming it with more air than it is designed to read through the change in electrical current as air passes over it.Modern cars are fitted with advanced electronic engine controls that estimate the right amount of fuel to be used in any situation. Also asked, what does a bigger MAF sensor do? This performance MAF sensor increases airflow by up to 45% and low-end torque. The performance mass airflow sensor replaces your OEM sensor and improves on mileage and can increase horsepower by 13. Just so, how much horsepower does a mass airflow sensor add?

However, with additional sensors and inputs, an engine's ECU can determine the mass flow rate of intake air. Neither design employs technology that measures air mass directly. These are the vane meter and the hot wire. There are two common types of mass airflow sensors in use on automotive engines. In addition, a faulty mass air flow sensor might cause the Check Engine or Service Engine Soon light to come on. Can mass air flow sensor affect acceleration?Īs a result, a bad mass air flow sensor causes various driveability problems, including a no-start, stalling, lack of power and poor acceleration.
