Mass Air Flow Sensor/Meter | O'Reilly Auto Parts

The mass air flow (MAF) sensor measures the mass flow rate of air entering the engine. This information is then used by the ECU to calculate the amount of fuel needed for the correct air-fuel mixture. If the mass air flow sensor has failed or needs to be cleaned, this can cause especially rich or lean fuel mixtures. That can result in hard starts or stalling after starting, or hesitation while ...

Thermal Anemometer Air Flow Sensors - DieselNet

If the engine is started up, a quantity of heat is removed from the sensor T1 positioned in front of the heater, while sensor T2, downstream of the heater, is still heated by the hot air film. Therefore the front sensor T1 is colder than the rear sensor T2—a temperature difference can be measured, which can be correlated with the flowing air mass. The return flow …

7 Symptoms of a Bad Mass Air Flow Sensor

2020-10-07· The mass air flow sensor measures the air mass flowing into the engine intake. Measuring air mass is critical in calculating how much fuel to add to achieve the correct air-fuel ratio (AFR). The ideal AFR is :1 ( pounds of air to pounds of gasoline), but real-world AFR varies. Acceleration might require a rich AFR, up to 12:1, while cruising requires a leaner AFR, sometimes as …

Mass Air Flow (MAF) vane sensor measurement

With a lab scope an air flow sensor is measured under the following conditions: key on, cranking, idle, 2000 RPM, 3000 RPM and back to idle with an engine at operating temperature. The signal from the sensor is shown and can be downloaded. To help determining whether an air flow sensor is functioning correctly, different deviations from the example signal are mentioned along with possible causes.
