Throttle Bodies

What does a Throttle Body do?

An Electronic Throttle Body is a device to control the flow rate of the air taken into an engine.
With an Electronic Throttle Body the depression of an accelerator pedal is converted to an electric signal and ECM (Engine Control Module) controls the DC motor to open or close the valve.
It is possible with an Electronic Throttle Body to open or close the throttle valve in responding to the operating condition of the vehicle. Compared to a mechanical type throttle chamber, ETB has higher preciseness and accuracy of throttle valve opening control and plays an important role to improve the fuel economy.
Relearning is required after replacement of the ETB in accordance with the instructions to ensure adequate performance.
