A mass air flow sensor, also known as a MAF sensor, is an important component in modern automotive engines. It measures the amount of air entering the engine, allowing the engine control module (ECM) to adjust the fuel delivery and optimize the air/fuel ratio for maximum performance and fuel efficiency. If your vehicle's MAF sensor is malfunctioning, it can cause a number of problems, including poor fuel economy, reduced power, and even stalling. Fortunately, replacing a faulty MAF sensor is relatively simple and inexpensive, and can restore your vehicle's performance and efficiency.
