The outside air entering the throttle flows through the sensor and into the engine, carrying away a significant amount of heat. The greater the airflow, the more heat is dissipated. To maintain the required temperature of the air flow sensor, additional current is used to heat the sensing element, allowing the system to measure and regulate the volume of incoming air based on the current required. If your vehicle experiences rough idling, weak acceleration, increased fuel consumption, or black smoke from the exhaust, it may indicate that the mass air flow sensor needs replacement. Replacing the MAF sensor helps improve fuel efficiency, supports the catalytic converter in reducing harmful emissions, lowers overall emissions, and helps prevent premature catalytic converter damage. Before installing the new Mass Air Flow Sensor, clean the air box and replace the air filter. Failure to do so may result in error codes or the Check Engine Light remaining on even after installation. The MAF sensor measures the volume and density of air entering the engine, delivering highly accurate airflow data to the ECU across a wide range of ambient temperatures.
