![]() ![]() In the majority of cases, after all the things are considered, it will be much cheaper and also better for your vehicle if you place the broken part. So whether you want it or not, you will not miss the red light from your vehicle! See, many car owners might not notice a decline in their car’s performance, but still, one can detect a decline in fuel economy anyway. When you take your car to the automobile service center, your mechanic will test the system and determine how bad the mass airflow sensor failure is. Please note that it is essential to replace a malfunctioning mass airflow sensor as soon as possible in this case because this will optimize the performance of your car’s engine! This means that your vehicle needs to be taken to your mechanic for diagnosis and further repair. The car will show a code on the dash and illuminate the check engine light when this happens. When this happens, your car will display you a code that will be indicating that a mass airflow sensor failure has happened. The airflow sensor can fail in several ways.īut one of the most common reasons for the failure of this part of a car is that it becomes contaminated, which causes it to malfunction. However, a mass airflow sensor is a mechanical thing and of course, it can get damaged or broken, which will result in some sort of malfunctioning. ![]() In this case, if the engine operates perfectly well, the car burns the fuel and operates with lower emissions efficiently. Why is this so important, you may be wondering? Well, simply because you want the engine of your car to perform at its best, just like any car owner would say. Like this, the car’s computer will then be able to adjust the engine accordingly for optimal performance. And also, it sends a reading to your car’s computer. This sensor measures the amount of air that is coming into the engine. infodramaticphotographerсom via VistaCreate What Happens If You Have A Bad Mass Air Flow Sensor?Īs we have already figured out before, the mass airflow sensor is an essential part of your car’s engine. In this case, this issue can lead to larger problems with your vehicle. If your car has a bad mass airflow sensor, the engine control module cannot calculate fuel injection correctly. See, the ideal air-fuel ratio for a car is 14.7:1 (where 14.7 pounds of air to 1.0 pounds of gasoline), but the air-fuel ratio in real life often varies.Īcceleration might require a rich air-fuel ratio, sometimes reaching up to 12:1, while cruising requires a leaner rate, sometimes as low as 22:1. You might not be aware of this, but measuring that air mass is critical in calculating how much fuel to add to achieve the correct air-fuel ratio. See, the mass air flow sensor in your car is a part of it that measures the air mass that is flowing into the engine intake. So perhaps, you have wondered about what a mass airflow sensor is.
