6C-7 Power Assisted Steering System:
5) Check relief pressure.
a) Increase engine speed to about 600 r/min. (rpm).
Close gauge valve gradually while watching
pressure increase indicated by gauge and take
reading of relief pressure (maximum hydraulic
pressure).
If it is higher than specified values, possible
cause is malfunction of relief valve.
If it is lower than specified values, possible
cause is either failure of P/S pump or settling of
relief valve spring.
Relief pressure when gauge value is closed
M16A Engine model: 6170 – 6870 kPa (61.7 –
68.7 kg/cm 2 , 877 – 977 psi)
J20A Engine model: 6560 – 7360 kPa (65.6 –
73.6 kg/cm , 933 – 1047 psi)
2
F9Q Engine model: 7650 – 8340 kPa (77.3 –
84.2 kg/cm 2 , 1099 – 1197 psi)
CAUTION
!
Be sure not to close gauge valve for longer
than 10 seconds.

b) Open gauge valve fully and increase engine
speed to about 1500 r/min. (rpm). Then turn
steering wheel to the left or right fully and take
reading of relief pressure.
If it is higher than specified values, possible
cause is malfunction of relief valve.
If it is lower than specified values, possible
cause is failure in steering gear case. Replace
gear case.
Relief pressure when gauge value is opened
M16A Engine model: 6170 – 6870 kPa (61.7 –
68.7 kg/cm 2 , 877 – 977 psi)
J20A Engine model: 6560 – 7360 kPa (65.6 –

F9Q Engine model: 7650 – 8340 kPa (77.3 –
84.2 kg/cm 2 , 1099 – 1197 psi)
CAUTION
!
Be sure not to hold steering wheel at fully
turned position for longer than 10 seconds.
