Pump Pressure Check - Honda CR-V 1997 Service Manual

Inspection and Adjustment
Pump Pressure Check With TIN 07406 - 0010001
Check the fluid pressure as follows to determine whether
the trouble is in the pump or gearbox.
1. Check the power steering fluid level (see page 17-
151. and pump belt tension (see page 17-141.
2. Disconnect the pump outlet hose from the pump
outlet with care so

6. Fully open the pressure control valve.
7. Start the engine and let it idle.
8. Turn the steering wheel from lock-ta-Iock several
times to warm the fluid to operating temperature.
9. Measure steady-state fluid pressure while the engine
is idling. If the pump is in good condition. the gauge
should read less than 1.500 kPa (15 kgf/cm'. 213 psi).
If it reads high. check the outlet hose or valve body
unit (see General Troubleshooting).
10. Close the pressure control valve. then close the
shut-off valve gradually until the pressure gauge
needle is stable. Read the pressure.
CAUTION: Do not k _ the pressure control valve
dosed m .... then 5 seconds or the pump could
be
damaged by over-heating.
11. Immediately open the pressure control valve fully.
If the pump is in good condition. the gauge should
read at least 6.900 - 7.800 kPa (70 - 80 kgf/cm'.
1.000 - 1.140 psil. A low reading means pump out-
put is too low' for full assist. Repair or replace the
pump.
