Mass Airflow Sensor Service

 Chevrolet Mass Airflow Sensor Service

Mass Airflow Sensor Service in Norwalk, NE

All internal combustion engines use a mixture of air and gas to power the engine. The air and fuel ratio must be correct in order for the oxygen in the air to combust the fuel for the movement of your vehicle. It should be at the correct ratio of 14.7 parts of air, to one part fuel for good fuel economy and peak engine performance.

What is a Mass Airflow Sensor and How Does it Work?

Your mass airflow sensors (MAF) measure the amount of air entering the engine. It then reports that amount to your power train control module, which in turn uses the input to calculate the engine load and adjust the air to gas ratio as needed. The most commonly used MAF uses two wires for sensing. One wire is heated and the other wire is not. The MAF computer determines the amount of air entering your engine by how much current it takes to keep the hot wire 200 degrees hotter than the unheated wire. As the temperature changes between the two wires, the MAF will increase or decrease current to the heated wire to move more air into the engine or less air into the engine as needed for combustion.

Signs of a Faulty MAF

There are some signs to alert you to needing MAF services. Your engine may run rich when it’s idling or it may run lean under a load. These items indicate that your MAF has a faulty hot wire from many different items. If you have a noticeable change in fuel economy, your MAF may continually be reporting the wrong information to your power train control module and it will need replacing. If your MAF has completely failed, it will not send any airflow information to the power train control module and the fuel won’t be controlled properly. This results in a very rough idling engine or an engine that won’t idle at all.
