How does a hot wire maf sensor work
WebDec 17, 2024 · The hot wire MAF sensor measures the flow of air with a heated element, which is cooled by air flowing through it. As the air cools the sensor, its current flow also changes and its internal circuitry then converts the current flow into an output voltage (proportional to the air coming through) called MAF Sensor Signal Voltage. WebOct 7, 2024 · The hot wire sensor heats a wire within the engine's air stream by applying a constant voltage to the wire, increasing the electrical resistance and the electrical current flowing through the circuit. As more current flows past the sensor, the wire’s temperature increases until the resistance reaches the proper balance once again.
