Proximal to this wire is a temperature sensor that measures air temperature near the wire. It is an electrically heated wire made of platinum and other materials of a similar conduction level. This sensor has a wire exposed to the air path. It relies on the principle of constant temperature.

This type of sensor is prominent in most modern vehicles. Working Principle of the Hot Wire Mass Airflow Sensor

Using the values, it will determine the amount of fuel that will go to the combustion chamber. The voltage signal goes to the engine control unit, which will determine the airflow rate. The slider movement causes a signal movement change, depending on the vane’s motion intensity. Incoming air will force the vane to rotate against the spring’s pressure.Īs the vane moves, the potentiometer’s slider pushes along the carbon track one end of the carbon track connects to the power supply unit. It uses a spring that holds a vane located in the air stream and connected to a potentiometer. Vane Mass Airflow Sensor Working Principleīack to the working principle, we will start with the vane mass airflow sensor. In this position, it is on the pathway of incoming air that goes to the combustion chamber. Where is the mass airflow sensor located? You will find this sensor located between the engine’s air filter and intake manifold in most vehicles. Each of them works in different ways to send signals to the car’s computer unit. There is the vane type and hot wire mass airflow sensor. Something that you should know is that there are two common types of mass airflow sensors. Mass Airflow Sensor Working PrincipleĪ look at the mass airflow sensor diagram will give you a slight hint of its working principle. If you have the same concern, you are in the right place as we look at its working principle and signs of a bad mass airflow sensor. Looking at the significance of this car sensor, it is not surprising that many people want to know how it works. It works effectively with an oxygen sensor for improved accuracy. The information helps the engine control unit to determine the fuel level supplied to the engine. Its primary role is to detect the air mass flow rate getting into the engine. The mass airflow sensor is a critical part of the internal combustion engine.

They help regulate certain functions or detect problems with different systems. Car sensors are essential components in a vehicle.
