Check of throttle knot check as follows:

Check smoothness and uniformity of turn of a butterfly valve.

Remove an air inlet branch pipe from throttle knot and check a condition in throttle knot on absence of deposits of soot and other pollution, especially round a butterfly valve. In the presence of pollution remove them with aerosol means for cleaning of carburetors and a toothbrush. Previously be convinced that aerosol means for cleaning will not damage the sensor of oxygen and catalytic converter.

     

PREVENTION Do not carry out cleaning of the sensor of provision of a butterfly valve (TPS) and the valve of a control system of frequency of rotation of idling (IAC)

Removal of throttle knot carry out on the cold engine as follows:

Switch off ignition and disconnect a "weight" wire from the storage battery.

Weaken collars and remove an air inlet branch pipe.

Disconnect an accelerator cable from the lever of a drive of a butterfly valve.

On models till 2001 with an automatic transmission, disconnect a management cable from the butterfly valve lever.

Fig. 5.24. Places of connection of hoses of system of cooling to throttle knot

Mark and disconnect from throttle knot vacuum hoses and hoses of system of cooling (fig. 5.24) .

Close plastic jams hoses of system of cooling that will prevent leakage of cooling liquid.

Disconnect the electric socket from the sensor of provision of a butterfly valve (TPS).

Fig. 5.25. An arrangement of bolts of fastening of throttle knot on models to 2001 годавыпуска till 2001

Fig. 5.26. An arrangement of bolts of fastening of throttle knot on models since 2001

Turn out bolts of fastening of throttle knot (fig. 5.25, 5.26) .

Remove throttle knot and laying from an inlet collector.

Installation of the engine is carried out to sequences, return to removal, taking into account the following:

At installation of throttle knot use new laying.

Check level and if necessary, add cooling liquid.
