The Mass Airflow Sensor is manufactured to OEM specifications, with durability, oxidation resistance, and high-temperature resistance, ensuring long-term stable performance. Replacing the MAF Sensor: The Mass Airflow Sensor is located between the air filter and the intake manifold, determining the quality of air entering the fuel-injected engine and transmitting this data to the Engine Control Unit or ECU. This balances the air-fuel ratio to promote successful combustion, but when your vehicle runs at idle, hard start, stall, and malfunction indicator lamp/code, it indicates that your airflow sensor needs to be replaced. Professional Factory Testing: Can quickly clear fault codes caused by the flowmeter. Complies with OEM specifications, super easy to install and clean, 30 millisecond fast response, high durability. When installing a new sensor, it must be ensured that the car's ECU is turned off. Some cars install new sensors smoothly but error codes still exist, the error codes must be cleared and then the new sensor installed. 12 Months Warranty: Provides you with a one-year warranty. Let you shop with confidence. In addition, if the MAF Sensor fails, is damaged, or has other issues, please feel free to contact us, and we will provide you with a satisfactory solution within 24 hours.
