17. INSPECT FLOW CONTROL VALVE ASSY
(a) Coat the flow control valve assy with power steering fluid and check that it falls smoothly into the flow control valve
hole by its own weight.
If necessary, replace the vane pump assy.
(b) Check the flow control valve assy for leakage. Close one
of the holes and apply compressed air of 392 to 490 kPa
(4 to 5 kgf
cm
2, 57 to 71 psi) into the opposite side hole,
and confirm that air does not come out from the end holes.
