Acura Legend Throttle Body
The Acura Legend's Throttle Body manages the amount of air entering the V6 engine. In response to driver input on the accelerator pedal, air begins to flow into the engine. The Powertrain Control Module perceives this airflow and adds fuel to create a compatible mixture for combustion, allowing for smooth acceleration. The Throttle Body Injection unit in the earlier Legend versions incorporated the use of a cable-attached Throttle Body, where one or two injectors were placed above the butterfly valve, which offered an inexpensive alternative to carburetors. When the pedal gets pressed, the plate moves open, extra air still rushes in, and the sensors urge the computer to widen the injector pulse width. Subsequent Acura sedans employed multi-port injection, whereby the Throttle Body controlled only air and separate rail injectors handled the fuel, while an Idle Air Control passage kept rpm steady. The newer versions introduced a Throttle Position Sensor and, in more recent years, a complete Electronic Throttle Control that replaced the cable with an electric motor for quicker response and integration with traction aids. Cleaning the unit can also stabilize the idle, but due to shifting in design, the shaft gets worn to the extent where the whole assembly has to be changed in older Acura Legend cars. For those who have an Acura Legend, it is important to understand the Throttle Body. Whether it's the original cable style or the newer motor-driven one, it is imperative to ensure crisp throttle response.
