![]() Loss of engine power – A bad mass airflow sensor will affect your engine’s ability to operate correctly.Engine stalling – A malfunctioning MAF sensor can cause the engine to stall or die unexpectedly.This can trigger the check engine light on your dashboard. Check engine light on – When the mass airflow sensor is not working properly, too much air could enter the engine and not enough fuel.The reduced air flow will affect the sensor’s ability to accurately read air levels in the engine, leading to problems with engine performance. Over time, contaminants such as carbon will find their way into the mass airflow sensor, creating a buildup which makes it harder for air to pass through. Aggressive driving and frequently driving in stop-and-go traffic can also put more strain on the sensor and cause it to wear out faster. For example, driving on dirt or gravel roads can expose the sensor to more dirt and debris, which can cause it to wear out faster. If the sensor becomes contaminated or damaged in any way, it may need to be replaced sooner than expected.Īdditionally, certain driving habits can also impact the lifespan of a MAF sensor. However, there are several factors that can impact the lifespan of a MAF sensor, such as exposure to dirt, dust, and debris, as well as exposure to extreme temperatures and humidity. For this reason, the sensor is generally not replaced until it fails. In fact, they have no scheduled replacement interval. Mass air flow sensors are designed to last the lifetime of your vehicle. How long does the mass airflow sensor last? Learn more about how the mass airflow sensor works If the air/fuel ratio is too rich (too much fuel), the MAF sensor will send a signal to the ECU to adjust the fuel injection accordingly. The MAF sensor also helps to ensure that the engine operates within safe parameters by monitoring the air/fuel ratio. The result is improved engine performance and fuel economy. ![]() The ECU makes changes to fuel injection, allowing for a correct air/fuel ratio within the engine’s combustion chamber. As the mass airflow sensor measures air levels, it sends this data to your car’s electronic control unit (ECU). It measures the mass or weight of the air entering the engine. The MAF sensor is typically located in the air intake system, close to the air filter. Its primary function is to measure the amount of air entering the engine, allowing the engine control module (ECM) to calculate the appropriate amount of fuel needed for efficient combustion. This scanner also can read and clear codes through every control module of your vehicle.The mass airflow sensor (MAF) is a critical component of a car’s engine management system. ![]() If you need to reset the check engine light after you have replaced the mass air flow sensor, you can use the YOUCANIC Full System Scanner to clear the stored codes and remove the check engine light on your Mazda. Step-by-step instructions on how to change the mass airflow sensor on a Mazda. These instructions include pictures and video clips to help you with this Mazda DIY repair. It is located on the engine air filter housing or the large-diameter air intake hose that connects the air clear box to the engine intake manifold. Where is the Mass Air Flow sensor located on a Mazda? If you are starting with DIY auto repair, this will be an easy task to get started. It is one of the simplest Mazda DIY repairs. The MAF sensor can be bought online for as low as $50. How much does a new Mazda air flow sensor cost?Īt the dealership, it will cost anywhere from $200 to $300. Cleaning is successful in cases when the sensor has gotten dirty. No guarantee cleaning will fix the problem. You can clean a Mazda airflow sensor using an Air Flow Sensor Cleaner. To confirm that the MAF is the problem, always read the fault codes using an OBD2 scanner. When the mass airflow sensor fails, your Mazda will not accelerate properly it may misfire and trigger the check or service engine light. How to tell if the mass airflow sensor is bad on a Mazda? Other DTCs not listed here may be related to the MAF sensor.
