Toyota RAV4>> The monitoring system and decrease in toxicity of the fulfilled gases>> System of a retsirkulyatsiya of the fulfilled gases (EGR) on models since 2001
To reduce the maintenance of an oxide of nitrogen in the fulfilled gases, the part of gases goes system of a retsirkulyatsiya of the fulfilled gases to an inlet collector therefore the combustion temperature goes down.
The system of a retsirkulyatsiya of the fulfilled gases consists of the EGR valve, the modulator, the switching vacuum valve (VSV) (it is located about a final collector) and vacuum hoses. The EGR valve copes vacuum on the basis of signals from the control unit the engine.
Replacement of the EGR valve make as follows:
– remove throttle knot;
– disconnect a vacuum hose from the EGR valve;

Fig. 7.26. An arrangement of the valve of system of repeated burning of the fulfilled gases (EGR)


– disconnect a hose of system of a retsirkulyatsiya of the fulfilled gases, turn out bolts and remove the EGR valve from an inlet collector (fig. 7.26) . If the EGR valve is littered, replace it, but do not wash out in solvent.
Installation make in sequence, return to removal.
Replacement of the vacuum EGR modulator and the filter make as follows:
– mark and disconnect vacuum hoses from the vacuum EGR modulator. Remove the vacuum EGR modulator from an arm;

Fig. 7.27. Removal of the filter from the EGR modulator


– if the modulator is repeatedly established, uncover and check a condition of its filters (fig. 7.27) ;
– clear filters, blowing them the compressed air. If filters cannot be cleared, replace them or the modulator.
Installation make in sequence, return to removal.
Replacement of the vacuum valve (VSV) make as follows:
– disconnect from the VSV valve the electric socket;
– mark and disconnect from the VSV valve vacuum hoses;
– remove the valve from an arm.
Installation make in sequence, return to removal.
