Removing and installing throttle assembly



The signs are not completely closing the throttle valve can be increased engine speed to idle and increased fuel consumption. When less than full throttle the engine may not develop full power, throttle response to be insufficient, in his work when the vehicle is possible jumps and dips. In these faults, first try adjusting the throttle actuator or replace the cable (see. "Adjustment and replacement of the throttle cable"). If this does not lead to a positive result, replace the throttle assembly.
You will need: the key "12" pliers.
1. Drain the engine cooling system (see. "Replacing the coolant").

NOTE
With a certain skill coolant can not be drained. Prepare a suitable size plugs that muffle hoses immediately after disconnecting them. Loss of coolant in such a method will be negligible.

2. Disconnect a wire from the plug "minus" of the storage battery.
3. Disconnect the engine wiring harness from the controller idle ...
4. ... and the throttle position sensor.
5. Disconnect from the sector throttle knot the accelerator cable (see. "Adjustment and replacement of the throttle cable").
6. Disconnect the hose from the intake pipe of small branches of the crankcase ventilation system.

NOTE
Disconnect the hose small branch of crankcase ventilation from the inlet pipe is needed in order to be able to ward off the throttle unit air supply hose.

7. Loosen the hose clamp, disconnect the air supply hose from the nozzle assembly of the throttle and move the arm to the side.
8. Loosen the hose clamp on the coolant supply, squeezing it with pliers bent tabs, slide the clamp on a hose ...
9. ... and remove the hose from the pipe of the throttle assembly.
10. Similarly disconnect the hose draining coolant.
NOTE
If you do not drain the cooling system, in order to avoid loss of liquid immediately stop the hose pre-prepared plugs or bolts of suitable size.

11. Disconnect the hose nozzle of the throttle assembly canister purge ...
12. ... and the EGR valve.
13. Remove the two screws on the throttle assembly to the intake manifold and remove the throttle assembly.
NOTE
Note that the compound of the throttle device and the inlet tube is sealed gasket. Strong compression or torn, replace gasket.

14. If the replacement of the throttle assembly on the new node is not set throttle position sensor 1 and 2 control idling, move them from the old site. To do this, remove the two screws attaching them.
15. If the throttle device is not removed for replacement, clean the contaminated fluid throttle device for cleaning carburetors, after removing it from the sensor and the controller. Clean and contaminated controller and sensor (Never use solvents for cleaning).
16. Remove from the oral intake pipe oil and other contaminants.
17. Set the throttle device in the reverse order of removal.
18. Adjust the throttle actuator (see. "Adjustment and replacement of the throttle cable").
19. If necessary, add coolant.
