Mass Air Flow Sensor

We have 1,527 Items for Mass Air Flow Sensor In-stock.

The performance of your vehicle engine relies on one equation: the right amount of fuel + the right amount of air = good engine output. Correct air-fuel ratio is so important that all vehicle manufacturers equip their vehicles with parts that will ensure the right ratio. In your vehicle, one of the most important parts is the mass air flow sensor. This is one of the many sensors that you will find in the intake system in your ride, designed to tell the engine computer just how much air is available for combustion. This way, the computer can determine the amount of fuel that it would need to send to the engine cylinders to match the amount of air available. The mass air flow sensor is important in preventing the occurrence of lean and rich air-fuel mixtures, which can cause a wide array of engine problems. Unfortunately, the sensor is vulnerable to such things as the very high temperatures typically experienced by different parts under the hood. Over time, the sensor might be damaged. How do you know when it already is? Well, you may experience stalling and misfiring, plus the illumination of the check engine light in your ride. If the mass air flow sensor is already damaged beyond repair, you must replace it immediately. Get your replacement here at Auto Parts Warehouse.

Tips on How to Replace a Broken Mass Airflow Sensor

A mass airflow sensor or MAF was designed to measure the amount of combustible air getting to the engine. It's responsible for making your vehicle's engine run smoothly. It can be damaged or contaminated by an improperly installed air filter. This will lead to problems like: engine stalling, poor acceleration, misfiring, lack of power, and the "Check Engine" light turns on. When these symptoms arise, it's time to change the mass airflow sensor.

In this guide, we have prepared the tips, steps and tools needed to finish the project.

Difficulty Level: Moderate

Tools that You'll Need:

  • Flat-head screwdriver
  • Phillips-head screwdriver
  • Torx-head screwdriver set (optional)
  • New Mass Airflow Sensor (MAF)

Safety Tips

  • Make sure that you're working on a solid, level surface.
  • Always wear recommended safety equipment like closed-toe shoes, an industrial-grade dusk mask, safety goggles and gloves.
  • Check your replacement parts and make sure that they are compatible to your vehicle's make and model.
  • Be careful with the mass airflow sensor replacement part. Do not touch the sensor's interior elements to avoid any contamination.
  • The mass airflow sensor's size depends on the vehicle's make and model. Consult your owner's manual or dealership for the correct type and make.

Step 1: Open your vehicle's hood and make sure it's secure.

Step 2 :Locate the engine's air box to remove the air filter. Some air boxes have metal clips to secure it. Use your fingers to remove the clips to open the air box.

Step 3 :The mass airflow sensor is usually located near the air filter housing or the intake tube.

Step 4: Remove the tube by using a Phillips screwdriver to unbolt the mounting hose clamps or rings.

Step 5: Unplug all the electrical connections from the sensor. Make sure to take note of their positions so you won't have problems reconnecting them.

Step 6: Remove all the mounting bolts securing the sensor to the body plate.

Step 7: Loosen and remove all mounting screws from the sensor's case. Remove all the tubes connected to it.

Step 8: Remove the old sensor from the case and make sure that all electrical wirings have been unplugged.

Step 9: Install the new mass airflow sensor and reassemble all the tubes connected to it. Make sure that the air tube is reconnected to the air box cover.

Step 10: Insert the air filter into the air box and secure the cover with the metal clips.

Step 11: Check if all the mounting clamps and bolts are secured. Plug the harness back into the sensor unit.

Step 12: Start your engine and check if the mass airflow sensor is working properly.

Installing a new mass airflow sensor will take about an hour for an expert DIYer and around an hour, 30 minutes for a beginner.
