Purpose, Function

Opens/closes the throttle valve to adjust the amount of air supplied to the cylinder.
Opens/closes the throttle valve according to the control signal from the PCM.

Construction

The throttle body is installed to the intake manifold.
The throttle body consists of a throttle valve, throttle valve actuator, TP sensor, and return spring.
For the throttle position sensor, refer to CONTROL SYSTEM..

Operation

The throttle valve actuator opens/closes the throttle valve according to the control signal from the PCM. If there is a malfunction in the throttle valve actuator, the throttle valve is closed by the return spring in the throttle body.
For the drive-by-wire control, refer to CONTROL SYSTEM..
