A mass air flow (MAF) sensor is a component found in the intake system of internal combustion engines that measures the flow rate of air entering the engine. It is typically located in the air intake duct or tube and is used to calculate the amount of fuel that needs to be injected into the engine based on the amount of air being drawn in.

The MAF sensor consists of a small tube with a heated wire or film element inside. As air flows past the wire or film, it cools the element, which causes a change in the resistance of the element. This change in resistance is used to calculate the flow rate of the air.

The MAF sensor is an important component of the engine management system, as it plays a key role in ensuring that the engine is operating efficiently and producing the correct amount of power. If the MAF sensor is not functioning properly, it can cause problems such as poor fuel economy, poor performance, and increased emissions.

The genuine Mazda MAF sensor (PE01-13-215) is a replacement part specifically designed for use in Mazda vehicles. It is an OEM (original equipment manufacturer) part, which means it is made by the same manufacturer that produced the part for the vehicle when it was built. OEM parts are typically considered to be of higher quality than aftermarket parts, as they are designed and tested to meet the same standards as the original parts.
