THROTTLE BODY FUNCTION [LF]

• An electronic throttle valve has been adopted
which opens and closes the throttle valve with the
actuator according to a signal from the PCM. It
enables precise intake air control at all engine
speed ranges.

THROTTLE BODY CONSTRUCTION/OPERATION [LF]

Construction

• The throttle body construction is as shown in the
figure.

Operation

• The actuator is driven by a duty signal from the
PCM. This driving force is transmitted to the
actuator gear, middle gear, and valve gear, and
the throttle valve opens.
• Conversely, to close the throttle valve, the
actuator is reversed by an opposite signal from
the PCM, and the throttle valve closes.
• The throttle valve opening angle is input to the
PCM by the TP sensor.
• The throttle body has a control spring. If a
malfunction occurs and the actuator cannot be controlled, the throttle valve is maintained balanced at an
opening angle of approx. 6 ° by the spring. Due to this, the required amount of air for vehicle operation is
ensured.
