What is an mass air flow sensor

  The Mass Air Flow (MAF) sensor measures the amount of air flow entering the intake manifold using a heated grid or wire. The PCM uses this signal primarily for fuel control.

  Please replace the air flow sensor according to manufacturer's recommendations based on mileage. And keep the inside of the air filter box very clean, and be sure the ducts between the air filter box and the throttle body are all securely clamped and airtight. 

The function of mass air flow sensor

  A mass (air) flow sensor (MAF) is used to find out the mass flow rate of air entering a fuel-injected internal combustion engine. 
(To measure all the air flowing into the engine)

How to replace an mass air flow 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.
