Genuine Mazda 626 Mass Air Flow Sensor

The Mazda 626 Mass Air Flow Sensor is a very accurate sensor that reads the inbound air to ensure that the engine computer mixes the fuel in an optimal way that provides reliable power and emits no harmful gases. Relied upon due to its extended lifespan, this small device made of aluminum always transmits data indicating airflow, changes in temperature and altitude, allowing the Mazda powertrain control unit to fine-tune fueling within milliseconds, allowing it to accelerate strongly and stabilize idle. The previous models relied on a vane design, which operated on the principle of a spring-loaded plate that moved, and was replaced by later generations relying on a hot-wire design using no moving parts, which reduced restriction and increased throttle response. Since the fitting is bolt-for-bolt across the 626 lineup, Mazda owners can change it and be sure that they can set it back to factory specs without any tricky recalibration. The tight tolerances of the sensor ensure that the catalytic converters are safer by avoiding rich mixtures which overheat the precious metals, which benefits the converters as well as adding a few extra miles to every gallon of gas. Midrange pull is crisp, emissions-test concerns are reduced and automatic shifts are smoother for drivers because of the correct airflow numbers that feed the PCM. Anti-humidity and anti-vibration protective coatings on the circuit board guard the delicate hot wire, and the inlet is tightly screened to keep out debris. Provided that a polluted Mass Air Flow Sensor manages to slip past the PCM with false readings, such symptoms as stalling or a glowing check-engine light are observed, which is why it is necessary to change the filters periodically and inspect the ducts. With the reinstatement of the original Mass Air Flow Sensor signal, even the worn-out 626 is reanimated, and this is why Mazda engineering remains known to be reliable and performance oriented.
