Note. Throttle actuator adjustment is shown on the VAZ 21124 engine (1,6i). Features of adjusting the throttle actuator on the VAZ 2112 engine (1,5i) indicated in the text.
Recommendation. It is necessary to adjust the throttle actuator after replacing the drive cable, after removing and installing the throttle assembly, and also after performing work related to the dismantling of the intake module. Throttle actuator adjustment may be required if the vehicle's engine may not develop maximum power due to incomplete throttle opening.
An assistant is required to perform the adjustment work.
Adjustment sequence
1. We prepare the car for work (see item 2a "Preparing the car for maintenance and repair").
2. Remove the engine trim (see "Decorative overlay of the engine - removal and installation").
3. After loosening the tightening of the three clamps, remove the air supply hose to the throttle valve.
4. We control the position of the throttle: with the pedal pressed «gas» (all the way to the floor) damper should be fully open..
...and with the pedal released «gas» - completely closed.
5. The position of the closed throttle valve is adjusted by the stop screw, turning it with a slotted screwdriver with a thin blade. The throttle valve should close completely without sticking.
The position of the open throttle valve is regulated by changing the tension of the cable of its drive.
Warning. When adjusting the open throttle, do not overtighten the cable, as this may damage the drive elements.
6. On the injection engine VAZ 2112 (1,5i):
Two 13 mm wrenches by turning the adjusting nuts (1 and 2), adjust cable tension (in the area between the throttle drive sector and the end of the shell, a slight sagging of the cable is allowed).
On the injection engine VAZ 21124 (l,6i):
A) Using pliers, remove the lock plate of the cable sheath.
b) By moving the cable sheath in the rubber holder, we adjust the cable tension (in the area between the throttle drive sector and the end of the shell, a slight sagging of the cable is allowed).
V) Install the retaining plate in place.
7. We check the operation of the throttle actuator. Repeat the adjustment if necessary.
8. We install on the car all the removed parts in the reverse order of removal.
