\nModern engines<\/a> depend heavily on accurate sensor data, and one of the most critical components is the air flow meter<\/strong>, also known as the MAF sensor (Mass Air Flow)<\/strong>.
When this small sensor fails, your engine\u2019s electronic control unit (ECU) loses one of its most important inputs \u2014 the precise measurement of air entering the engine. The result? A faulty air flow meter<\/strong> can trigger a chain<\/a> reaction of problems: poor acceleration, rough idle, black smoke<\/a>, and even engine shutdown.<\/p>\n

In short, the MAF sensor acts as the \u201clungs\u201d of your engine\u2019s intelligence system. When it misreads, the entire breathing process goes wrong.<\/p>\n

\u2699\ufe0f How the air flow meter works<\/h3>\n

The MAF sensor is installed between the air filter and the intake manifold. Inside, it uses a heated wire or film element<\/strong>. As air passes through, it cools that wire. The more air that flows, the greater the cooling effect.
The sensor converts this change in temperature into an electrical signal, which is sent to the ECU.<\/p>\n

The ECU then uses this signal to:<\/p>\n
