Fig. 5: Identifying Pressure Control Valve 9. Fully open the pressure control valve (B). 10. Start the engine, and let it idle. 11. Turn the steering wheel from lock-to-lock several times to warm the fluid to operating temperature at 158°F (70°C). 12. Measure steady-state fluid pressure while the engine is idling. If the pump is in 2
good condition, the gauge should be no more than 1,470 kPa (15 kgf/cm , 213 psi). If it reads higher, check for: Clogged or deformed pump outlet or return line between the pump and the steering gearbox. Clogged valve body unit. 13. Raise the engine speed to 3,000 rpm, and measure the fluid pressure. If the pump is in good condition, the gauge should read at least 1,470 kPa (15 2
kgf/cm , 213 psi). If it reads higher, repair or replace the pump. 14. Lower the engine speed, and let it idle. Close the shut-off valve, then close the pressure control valve gradually until the pressure gauge needle is stable. Read the pressure. NOTE:
Do not keep the shut-off valve closed more than 5 seconds or the pump could be damaged by overheating.
