Mass Air Flow Engine Snap Shot


There are various sensors in an automobile including the oxygen sensor, mass air flow sensor, knock sensor, vehicle speed sensor and air fuel ratio sensor. The engine of a car is monitored by many systems and information from these systems are fed into the main Engine Control Unit (ECU). This information is available to the mechanic as an "engine snapshot" which can tell the mechanic if the sensors are working correctly.

The image above shows the snapshot of the readings of the mass air flow sensor and other sensors. The mass air flow sensor (MAF) measures the mass of air flowing into the engine's intake manifold. The ECU records this reading and sends the appropriate amount of fuel to the engine to maintain the perfect air-fuel ratio. If there is an issue with the MAF (Mass Air Flow Sensor) the readings will be way out of specifications from what they are supposed to read. The mechanic can obtain the correct specifications from the dealership.


Some of the common indications of a defective MAF sensor include decreased engine efficiency and increased emissions. In addition, a faulty sensor will cause your Check Engine to glow in your vehicle's dashboard.
