Aug 6, 2023 路 The mass air flow sensor measures the amount of air entering the engine. Mass Air Flow Sensor Symptoms . Because the MAF is a primary input to your car鈥檚 computer for fuel control (more on that later), the sensor can cause several noticeable symptoms when it fails. Some of the most common air flow sensor problems include:
Mar 2, 2023 路 The most common symptoms of a bad mass air flow sensor are engine performance issues such as rough acceleration or rough idling, along with a check engine light on your dashboard. You may also notice changes in fuel consumption, or black smoke from the exhaust.
Apr 14, 2022 路 The primary role of the MAF sensor is to measure the mass of the air flowing into the engine and then relay that data to the control unit, which is used in determining the amount of fuel to burn. Note that 14.7kg of air is the ideal amount the engine requires to burn 1kg of fuel optimally. So, the MAF plays a significant role in ensuring your
Jul 17, 2021 路 The engine computer (PCM) calculates how much fuel to inject based on the mass air flow sensor measurements. If there is a vacuum leak anywhere between the engine and the mass air flow sensor, it causes "unmetered" air to enter the system. This causes the actual air flow to be higher than the mass air flow sensor measures.
Mar 6, 2023 路 6. Sluggish Acceleration. Slow acceleration and poor fuel economy could be signs that your Mass Airflow (MAF) sensor needs replacing. The MAF sensor is responsible for informing the engine鈥檚 computer how much air is entering the engine, so if it鈥檚 faulty, the car won鈥檛 be able to adjust itself and will run inefficiently.
