3.

INSPECT FLOW CONTROL VALVE
(a) Coat the flow control valve with power steering fluid 

and check that it falls smoothly into the flow control 
valve hole under its own weight.

(b) Check the flow control valve 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) to the hole on the 

opposite side. Confirm that the air does not flow out 
from the end holes.
If necessary, replace the vane pump assembly.

4.

INSPECT COMPRESSION SPRING
(a) Using vernier calipers, measure the free length of 

the spring.
Minimum free length:

29.2 mm (1.150 in.)

If it is not within the specification, replace the vane 
pump assembly.

5.

INSPECT PRESSURE PORT UNION SUB-ASSEMBLY
(a) If the union seat in the pressure port union is badly 

damaged, it could cause fluid leakage, so replace 
the vane pump assembly.
