mass air flow sensor how it works

How they work - Denso

How they work. The Mass Air Flow Sensor measures the amount of air volume flowing into a car’s engine, and sends the Electronic Control Unit (ECU) a voltage that represents the airflow. Currently the most common MAF sensor is the plug-in hot wire type which is located inside the intake air duct between the air filter and the throttle body.

Air Mass Sensors · Technipedia · Motorservice

The air mass sensor precisely measures the air mass that flows into the engine (“mass air flow”). The signal from the air mass sensor is used to calculate the injected fuel quantity. In diesel engines, it also controls the exhaust gas recirculation. It is an important component in air supply and helps reduce exhaust gas. A defective or contaminated air mass sensor can convey incorrect ...

What Does a Performance MAF Do? | AutoAnything Resource Center

2018-11-25· What Does a Mass Air flow Sensor Do? Your mass air flow sensor or “MAF” detects the volume of air as it enters your engine by heating up a thin wire or resistor. The computer in your car then measures electrical resistance through the MAF as the air flowing through the sensor cools its components down. With a firm understanding of how much air is flowing into your engine, the …

what's a mass air flow sensor and how does it work ...

2007-12-20· Mass air flow sensors simply measures how much air is going into the engine, then the ECM takes this number and calculates how much fuel to inject to maintain the correct air/fule ratio. Mass air flow sensing sytems work very well on engines with larger camshafts, or low manifold vacuum. The other style of measuring air flow is a MAP sensing system. By measuring the manifold vacuum versus ...

Types of Flow Sensors: Flow Sensor Principles Explained ...

2020-10-08· A flow sensor is a component that measures the flow of a fluid such as a gas or liquid. Flow sensors utilize both mechanical and electrical subsystems to measure changes in the fluid's physical attributes and calculate its flow. Measuring these physical attributes depends on the fluid's physical attributes. Gaseous, liquid, and non-Newtonian fluids behave vastly different from one …

How to Replace a Mass Air Flow Sensor

2019-01-15· How a Mass Air Flow Sensor Works. Like its name suggests, this is a sensor that measures the amount (mass) of air flowing into a fuel-injected engine. The way it does this is rather ingenious. The electrical system heats a hot wire anemometer in the air intake tube to well over 100 degrees. As air passes over the wire on its way to the engine, the air flow cools the wire. The …

What Does the Mass Airflow Sensor Do? | YourMechanic Advice

2015-11-17· Since the function of an MAF is to measure all the air flowing into the engine, they have a LOT of air flowing through them. Try to imagine 9,000-10,000 gallons of air flowing through your engine for every 1 gallon of gas burned! That much air carries a lot of fine dust and particulates of all types. It is the job of the air filter to keep that all that junk off of the MAF, as well as out of ...

Thermal Mass Flow Sensors. What Is Their Working Principle?

2018-09-03· Probe-style mass flow sensors are used to measure air flows and are insensitive to the presence of moderate amounts of dust. They maintain a temperature differential between two RTDs mounted on the sensor tube. The upper sensor measures the ambient temperature of the gas (Figure 5-10A) and continuously maintains the second RTD (near the tip of the probe) at 60°F above ambient. …
