What is the material of the wire placed in mass air flow sensor?
What is the material of the wire placed in mass air flow sensor?
Working Principle of the Hot Wire Mass Airflow Sensor It relies on the principle of constant temperature. This sensor has a wire exposed to the air path. It is an electrically heated wire made of platinum and other materials of a similar conduction level.

What kind of air flow sensor do I need for my MAF?
Depending on the year and make of the vehicle, you may find different types of mass air flow sensors, from the old-style vane air flow meter to the modern era hot-wire mass air flow meter. Since hot-wire technology is the most widely used today, we’ll assume that your MAF is using that design.
How does a hot wire air flow sensor work?
How a hot-wire air flow sensor works. A hot-wire mass air flow sensor has a small electrically heated wire (hot wire) and a small temperature sensor installed close to the hot wire. The temperature sensor measures the temperature of the air near the hot wire. When the engine is idling, a very little air flows pass the hot wire,…
What are the different types of air flow sensors?
Depending on the type of construction: 1 A sensor which measures the volume (l / h) of the air flow – Vane Meter Sensor (VAF and also known as LMM). 2 A sensor which measures the mass (kg/h) of the air flow – Hot Wire MAF sensor (also known as HLM). 3 A sensor which measures the mass (kg/h) of the air flow – Hot Film MAF (HFM).
What are the problems for a mass air sensor?
Mass Air flow Sensor Problems and symptoms The Engine Runs Lean or Rich. If the “mass air flow sensor” is always giving wrong information to the car’s computer, then the engine of the car may run Turning over is difficult. When the “mass air flow sensor” is faulty, it can be hard to turn over the engine. Stalling the car. Engine Drags.
What is the function of a mass airflow sensor?
Mass airflow sensors, or MAF sensors for short, measure the density of the air passing through an engine’s intake and report to the ECU ( engine control unit) computer, allowing it to deliver the right amount of fuel through the injectors and into the combustion chambers.
Does mass air flow have a fuse?
The mass air flow sensor is in the main air duct slightly past the air box where the air filter it located Its clamped inside the duct so all of the air that comes through the duct from the air box has to pass through it. there is not fuse for it This sensor measures the amount of air entering the engine and sends a voltage signal to the VCM.
What does a mass airflow sensor (MAF) do?
A mass airflow sensor. A mass (air) flow sensor (MAF) is a sensor used to determine the mass flow rate of air entering a fuel-injected internal combustion engine . The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine. Air changes its density with temperature and pressure. Oct 23 2019
