The throttle assembly is the simplest control device and serves to change the amount of main air supplied to the intake system
An air filter is put on the inlet pipe of the throttle assembly, the connections of the throttle assembly with the intake pipe and the air filter are sealed with rubber gaskets.
A hole is made in the throttle assembly housing for supplying additional air to the idle speed controller.
In housing 5 (Fig. 1) there is a damper 3 that rotates on an axis.
At one end of the axle there is a sensor 4 of the throttle position of the engine management system, at the other end is lever 2, to which the intermediate thrust of the throttle actuator is attached.
An idle speed regulator 1 is fixed on the housing 5, which doses the air flow with the throttle closed.
During operation, the throttle assembly does not require maintenance and adjustment, only monitor the condition of the rubber seals to avoid air leakage.
Removing and installing the throttle body
You will need a flat-blade screwdriver.
Disconnect the wire from the negative terminal of the battery.
Remove the air filter (see Removing and installing the air filter).
Press the latch and disconnect the wiring harness connector from the throttle position sensor.
Press the latch and disconnect the wiring harness block from the idle speed control
Using a screwdriver as a lever, disconnect the intermediate throttle actuator rod from the throttle assembly lever
Remove the throttle assembly.
Remove the sealing rubber ring from the throttle assembly and inspect it.
Replace a cracked or torn ring with a new one.
Install the parts in the reverse order of removal.
