Simple Air Mass Meter Installation Guide

The main function of an air mass meter is to measure the amount and density of the air that enters the combustion chamber of a vehicle. Also referred to as the air flow sensor, this component allows the car's mechanical system to know how much fuel is needed in order to compensate the amount of air in the engine during combustion. Without a well-functioning air mass meter, it would be very difficult for the car's computer to determine the proper air to fuel ratio, and this could make it harder for drivers to get the best performance of their vehicles.

Required skill level: Novice

Needed tools and materials:

  • Brand new air mass meter
  • Phillips-head screwdriver
  • Finding the air mass meter location

    Pop the hood of the car and determine where the mass meter should be installed. It is usually located on the area where the air filter is also placed. The air flow sensor is supposed to be located on the left side of the air box where a small harness is connected.

    Installing the air flow sensor

    Get the Phillips screwdriver and the air mass meter. Start screwing the mass meter onto the intake tube in the proper position. Make sure that the sensor is screwed tight so it does not fall off.

    Clipping the mass meter

    Clip the mass meter to the wiring harness after putting the screws. You can simply use your fingers in this step since the wires are unplugged and power is out.

    Plugging the wiring harness

    Put the wiring harness back by plugging it after clipping the air flow sensor. Use the same harness found on the air intake system, especially if it is still in good working condition.

    Re-attaching the wire on the air box

    Clip the harness on the air box once it is properly plugged. Make sure that everything is placed back in order before closing the hood.

    Analysis of the car computer

    Assess the car computer and see if the new air mass meter is working. You should be able to see a numeric display in order to know if the mass air flow sensor is functioning. Using a scanner is necessary, but if a scanner is not available, you may ask for the assistance of an automotive expert.

      Without a well-functioning air mass meter, it would be impossible for a vehicle's internal combustion engine to work properly. This is because the meter is responsible for measuring the amount and density of the air that comes to the system. In order to combust enough fuel and make the vehicle run, it is imperative for the car to get the right amount of fuel mass, especially since the substance's density changes due to temperature and constant pressure. For a lot of consumers, however, choosing the right air mass meter still remains challenging, despite the fact that there is an abundance of options for in the market. So, we came up with a simple guide to help you solve this dilemma.

      Product evaluation

      A1 Cardone makes it a point to evaluate and re-evaluate the products that it releases in the market. Although Bosch does the same to its air mass meters, the people behind A1 Cardone takes the time to assess their sensors that failed to reach meet the standards of the company. The brand follows a process called "reverse-engineering" where substandard air flow meters get re-evaluated and remodeled.

      WINNER: A1 Cardone

      Vehicle Coverage

      To know which brand caters to more consumers and car models, we temporarily installed the A1 Cardone and Bosh air flow sensors to different vehicle types and tested if they will still work. Both brands yielded positive results and we have proven that they have the same specifications as the original parts of most car models.

      WINNER: Bosch and A1 Cardone

      Price

      A1 Cardone's air mass meter has a slightly lower price than Bosch. The mass flow sensors from A1 Cardone are offered within the range of $100 to a little over $200, while their Bosch counterparts are priced quite higher at around $180 to $280.

      WINNER: A1 Cardone

      The verdict

      Quality and performance-wise, A1 Cardone and Bosh air mass meters are at par with each other. The only difference lies on the price. And since A1 Cardone products are cheaper than Bosch's, its products become more appealing to consumers, particularly to those who are looking for cheaper alternatives without compromising the quality of the mass flow sensors.
