When this sensor is unplugged, the ECU gets switched to limp mode. We already know that mass airflow sensors estimate the quantity of air inflowing the engine. This brings us to what happens when the mass airflow sensor is unplugged. What Really Happens On Unplugging The Mass Air Flow Sensor However, if the car dies on unplugging the mass airflow sensor, this means that either the computer or some other sensor is malfunctioning.

To check whether the computer is working perfectly.Īfter unplugging the mass airflow sensor, if the car continues to function properly or ends up performing better than usual, it indicates that something is wrong with the mass airflow sensor.

In order to check whether the other sensors are working correctly.

To check whether the mass airflow sensor is working properly.

There are three main reasons to unplug the mass airflow sensor of a car: Why Do We Unplug The Mass Air Flow Sensor? It then assesses the movement of the waves to deduce the volume of air entering the engine. As the name suggests, the air is made to pass through a vortex equipped with waves. This helps it estimate the volume of air entering the engine.Īnother type of mass airflow sensor is the vortex type. It measures how much current is needed to keep the wire hot. The hot wire type mass airflow sensor uses two wires, one hot and one cold.

The hot wire type mass airflow sensor is the type, which is most common out there. A mixture of fuel and air in the correct ratio leads to combustion, which keeps the car running smoothly.ĭifferent types of mass airflow sensors use different techniques to measure the volume and density of the air entering the engine. The mass airflow sensor detects how much air is going into the car’s engine so that it can push the right amount of fuel. However, one should not assume that it is not an essential component.īefore we dive into explaining why this happens, it’s necessary to understand a few fundamental facts regarding the mass airflow sensor. It’s quite a fascinating fact for many that a car seems to run better when its mass airflow sensor is unplugged.
