Hitachi® ETB0019 - Fuel Injection Throttle Body

The electronic throttle body (ETB) is a main part of an electronic throttle control (ETC) system. The ETB controls the volume of air flow entering the engine. It features a butterfly valve which opens and closes according to a signal from the engine control unit. With an electronic control throttle body, it is possible to open or close the throttle valve according to the changing condition of the vehicle. Compared to a mechanical type throttle body, it is a system of higher accuracy that allows for increased fuel economy.

If your idle speed is reduced, your engine stalls when warmed up, restarted, or during acceleration, chances are you have a malfunctioning throttle body. Get a top-grade ETB from a trusted, world class quality leader and an original equipment manufacturer, and you'll have a reliable part that functions flawlessly mile after mile. Unlike a traditional throttle body with an accelerator cable, this electronic throttle body by Hitachi utilizes a microcomputer to control the valve opening quickly and accurately. Precision is essential to keep engine torque at a constant level when maintaining the proper air/fuel ratio. A more accurate ETB allows for better fuel economy and emissions performance.
