Is your car in need of a new mass airflow sensor? If so, we can help! At Grimmer Motors, our team of experienced mechanics can diagnose and replace your old mass airflow sensor plus install a new one. Mass Airflow Sensor Replacement in Hamilton Increased emissions – A faulty MAF sensor can cause the engine to produce excessive emissions, which can result in a failed Warant of Fitness.This can be caused by a damaged Mass Air Flow (MAF) sensor. Rough idle – Your vehicle may operate roughly with increased engine RPM while idling.This will result in incorrect amounts of fuel entering your engine and the fuel not being used optimally. Increased fuel consumption – A faulty mass airflow sensor will give incorrect readings to your car’s ECU.You may experience a significant reduction in acceleration or the car may struggle under heavy loads or to idle properly. 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. ![]() The mass airflow sensor (MAF) is a critical component of a car’s engine management system.
