This system controls flow rate of EGR led from exhaust manifold
to intake manifold. The opening of the EGR by-pass passage in the
EGR volume control valve changes to control the flow rate. A
built-in step motor moves the valve in steps corresponding to the
ECM output pulses. The opening of the valve varies for optimum
engine control. The optimum value stored in the ECM is determined
by considering various engine conditions.
The EGR volume control valve remains close under the following
conditions.
+Engine stopped
+Engine starting
+Low engine coolant temperature
+Excessively high engine coolant temperature
+High engine speed
+Wide open throttle

COMPONENT DESCRIPTIONNJEC0764S02EGR Volume Control ValveNJEC0764S0201The EGR volume control valve uses a step motor to control the flow
rate of EGR from exhaust manifold. This motor has four winding
phases. It operates according to the output pulse signal of the
ECM. Two windings are turned ON and OFF in sequence. Each
time an ON pulse is issued, the valve opens or closes, changing
the flow rate. When no change in the flow rate is needed, the ECM
does not issue the pulse signal. A certain voltage signal is issued
so that the valve remains at that particular opening.

b. Install outer race onto differential side bearing on final gear
side. Holding lightly the outer race horizontally by hand, rotate
final gear five times or more (for smooth movement of bearing
roller).
c. Using dial gauge and scale as shown in the figure, measure
dimension ªN2º between differential side bearing outer race
and transaxle case end face.

5. Measure turning torque of final drive assembly.
Turning torque of final drive assembly
(New bearing):
2.9 - 6.9 N´m (30 - 70 kg-cm, 26 - 61 in-lb)
+When old bearing is used again, turning torque will be
slightly less than the above.
+Make sure torque is close to the specified range.
+Changes in turning torque of final drive assembly per
revolution should be within 1.0 N´m (10 kg-cm, 8.7 in-lb)
without binding.

6. Calculate dimension ªOº (thickness of adjusting shim) using
the following procedure to satisfy specification of end play for
input shaft rear bearing.
End play: 0 - 0.06 mm (0 - 0.0024 in)
Dimension ªOº = (O1 ± O2) + End play
O: Thickness of adjusting shim
O1: Distance between transaxle case end face and
mounting face of adjusting shim
O2: Distance between clutch housing case end
face and end face of input shaft rear bearing
Input shaft rear bearing adjusting shims:
Refer to SDS, MT-128.
