2.30. Valve check of system of recirculation of the fulfilled gases (EGR)
The valve of system of recirculation of the fulfilled EGR gases is installed on an inlet collector near the carburetor. In most cases malfunctions in system of production of the fulfilled gases are caused by jamming or corrosion of the EGR valve.
On the cold engine from below from under the EGR valve manually move a diaphragm. Putting moderate pressure, you have to move a diaphragm within the case up and down.
If the diaphragm does not move or moves only at application of big effort, replace the EGR valve. If you are not sure of serviceability of the valve, compare free movement of your EGR valve to movement of the new valve.
