Electronic Throttle Valve Body Assembly; Disassembly Requirements - Segway VILLIAN SSV Series Service Manual

ELECTRONIC THROTTLE VALVE BODY ASSEMBLY

The electronic throttle valve body assembly is connected to the engine and the air filter, and the
electronic throttle body is installed in the intake system of the engine.the air fl ow into the cylinder is
controlled by adjusting the angle of the throttle valve plate.its main function is to adjust the opening
and closing angle of the throttle valve plate according to the driver's driving intention to meet the intake
demand of the engine under diff erent operating conditions. At the same time, it feeds back the position
signal of the throttle valve plate to the control unit for precise control.the valve body assembly includes:

Disassembly requirements

◆ It is strictly forbidden to disassemble the charged electronic throttle body.
◆ The electronic throttle body can be disassembled after the vehicle is cooled to room temperature to
prevent the black cover and connectors from being wetted by the overheated antifreeze liquid.
◆ During the disassembly process, disassemble the mounting bolts diagonally, with even force, not
to damage the upper and lower mounting surfaces, and at the same time ensure that the electronic
throttle body does not fall or hit.
