[Working Principle] The outside air entering the throttle flows through the sensor. As air passes through, it absorbs heat from the sensor. The greater the airflow, the more heat is absorbed. To maintain the sensor's required temperature, additional current is used to heat the element, allowing the system to measure and regulate the air flow based on the current required. [Replace in Time] If your vehicle experiences rough idling, weak acceleration, increased fuel consumption, or black smoke from the exhaust, it may indicate that the air flow sensor needs replacement. Replacing the sensor can help improve fuel efficiency, support the catalytic converter in reducing harmful emissions, lower overall emissions, and help prevent premature damage to the catalytic converter. [NOTE] Please clean the air box and replace the air filter when installing this Air Flow Sensor. Failure to do so may result in error codes or the Check Engine Light remaining on even after installation. This Air Flow Meter measures the volume and density of air entering the engine, delivering accurate readings to the ECU across a wide temperature range.
