What is a maf sensor?
MAF SENSOR also known as Mass Air Flow Meter/ Air Flow Sensor/ Air Mass Meter/ Air Mass Sensor. It s the device used in many fuel injected engines to measure the amount of air entering the engine so the onboard computer (ECU) can calculate the correct air/fuel mixture ratio to enter the combustion chambers. Located ahead of the throttle body, after the air filter, the MAF sensor uses a heated wire or filament/film to measure the air flow.

How To Install The Replacement Mass Air Flow Meter Sensor:
1. Position MAF sensor in the vehicle. Make sure the airflow direction indicated on the sensor is toward the engine.
2. Install sensor-to-air-duct seal(s), if so equipped, on the replacement MAF sensor.
3. Connect the MAF sensor to the throttle body air cleaner ducts. If the sensor mounts directly on the throttle body, install and tighten the mounting screws to 10 ft-lb. DO NOT OVERTIGHTEN!
4. Position clamps over the air duct/MAF sensor connections and tighten; Replace the clamps if necessary.NOTE: For the MAF sensor to work properly, the sensor/air duct connections must be airtight.
5.CAREFULLY plug the harness connector lead into the MAF sensor.
