What is MAF sensors?
MAF sensors are located between the air filter and the throttle body and are responsible for measuring the amount of air entering the engine. It then sends the data to the ECU. Based on this data, the ECU directs the fuel injection system to achieve the ideal air-fuel mixture as demanded. It is also responsible for adjusting the amount of fuel delivered to the engine for better efficiency. A faulty sensor can result in a significant loss in power, poor gas mileage, and frequent engine stalls.
How to replace the MAF sensors?
Step 1: Disconnect the electrical connector from the mass air flow sensor. Squeeze the tab on the harness side of the electrical connector while firmly pulling on the connector. Remember, do not pull on the wires, only the connector itself. It helps to use gloves with a rubberized coating if your hands are slipping off the connector.
Step 2: Disconnect the mass air flow sensor. Use a screwdriver to loosen the clamp or screws on each side of the MAF that secure it to the intake pipe and air filter. Once the clamps are removed, you should be able to pull the MAF right out.
Tip: There are many different ways a MAF sensor is secured. Some have screws that hold it to an adapter plate which attaches directly to the airbox. Some have clamps that hold the sensor in-line of the intake pipe.
Step 3: Connect the new mass airflow sensor. The sensor slides into the intake and then is clamped on. Make sure all the clamps and screws are snug, but do not overtighten them as the sensor is plastic and can break if handled too roughly.
Warning: Use extra care to not touch the element of the sensor on the inside of the MAF. The element will be exposed when the sensor is removed and it is very delicate.
Step 4: Reconnect the electrical connector. Reconnect the electrical connector to the new mass airflow sensor by sliding the female side of the connector over the male side that is attached to the sensor. Press firmly until you hear a click that indicates the connector is seated all the way and locked into position.
point: double check all your work to make sure you haven鈥檛 left anything loose and the job is complete.
