If your MAF sensor is consistently reporting inaccurate information to your car’s computer (for example, due to deformation of the wire, or damage to the electrical equipment), then your engine will either consistently run lean or rich. Your Engine Consistently Runs Lean or Rich Common signs of a failing MAF sensor include: 1. Your car uses this number for multiple calculations, which is why keeping your MAF sensor running properly is important.
This type of sensor measures the amount of current necessary to maintain the temperature of a wire above 90 degrees, which in turn gives your car’s computer a measure of the mass of the air entering the engine. This is important as it allows your engine to regulate its performance and change the intake of air to keep your engine running in its best condition.īy far, the most common type of MAF sensor is a “hot-wire” MAF sensor. Your Mass Air Flow Sensor (MAF Sensor) is a piece of technology within your engine which tells your car’s computer how much air is entering the engine.
