The engine receives the exact air it requires due to the Mazda 626 Throttle Body, which gives the engine responsive power and amazing fuel economy. This aluminium-housed unit, with its butterfly plate, sits between the air filter and intake manifold, and when the driver presses the accelerator, airflow increases in proportion to pedal angle. The built-in sensor transfers said movement directly to the Powertrain Control Module, and the computer is able to adjust fuel and spark to provide clean combustion, smooth acceleration, and lower emissions. The Mazda 626 benefits drivers of the first to the last generations since the Throttle Body can directly connect to both the early cable-controlled versions and the more recent electronic drive-by-wire versions and is therefore compatible across sedans, coupes and hatchbacks of the same nameplate. On models that retained single-point injection, the integrated injectors with a pressure regulator reduce the distance that the fuel has to travel to allow cold starts to happen quicker, and the later multi-port type retains only the housing centered on airflow, further dropping the temperature in the intake path and squeezing out an additional mile per gallon. The idle air control valve is fed by a special channel and thus the main plate may remain closed when traffic stops, allowing a constant idle flow without wasting fuel. The electronic model also includes twin pedal sensors and an internal motor that opens or closes the blade within milliseconds to work with traction and cruise control to prevent wheel slip and ensure that the car maintains speed at safe levels on wet roads. The part has a good reputation for long life due to the strong construction and anti-corrosion coating but sometimes cleaning is done to maintain the Mazda balance that the owners are accustomed to. Combining a level of durability, model range, and intelligent electronic protection, the Throttle Body is a smaller, yet important, element that allows every Mazda 626 to punch above its weight in reliability, economy and driving pleasure.
