6. Fully open the pressure control valve (B).
7. Start the engine, and let it idle.
8. Turn the steering wheel from lock-to-lock several times to warm the fluid to operating temperature at 158 °F (70 °C).
9. Measure steady-state fluid pressure while the engine is idling. If the pump is in good condition, the gauge should read no more than 1,470 kPa (15
kgf/cm2, 213 psi).
If the reading is high, check for:
-
Clogged or deformed inlet or return line between the pump and the steering gearbox.
-
Clogged valve body unit.
10. Let the engine idle, and gradually close the shut-off valve and immediately read the pressure.
NOTICE
Do not keep the shut-off valve closed more than 5 seconds or the pump could be damaged by over-heating.
11. Immediately open the shut-off valve fully. If the pump is in good condition, the gauge should read at least 8,150-8,850 kPa (83-90 kgf/cm2,
1,181-1,280 psi). A low reading means the pump output is too low for full assist. Repair or replace the pump.
