9. Measure steady-state fluid pressure while the engine is idling. If the pump is in good condition, the pressure should be no more than 1,500 kPa (15 kgf/cm 2 , 214 psi). If the pressure is too high, check the outlet hose or valve body unit (see Steering System Troubleshooting). Raise the engine speed to 3,000 2 , 214 psi). If the pressure is too high, repair or replace the pump. 10. 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. 11. Immediately open the pressure control valve fully. If the pump is in good condition and the valve is closed, the gauge should read at least this specification: 7,850-8,550 kPa (80-87 kgf/cm 2 , 1,140-1,240 psi) A low reading means pump output is too low for full assist. Repair or replace the pump. PUMP PRESSURE TEST WITH T/N 07406-001000A Special Tools Required: z P/S joint adapter (pump) 07VAK-P8A011A z P/S joint adapter plate (pump) 07ZAK-S7CA100 z P/S joint adapter (hose) 07ZAK-S7CA200 z P/S pressure gauge 07406-001000A 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 FLUID REPLACEMENT ). 2. Disconnect the pump outlet hose (A) from the pump outlet with care so as not to spill the power steering fluid on the frame and other parts. Install the P/S joint adapter (pump) on the pump outlet (B). NOTE: Do not keep the shut-off valve closed more than 5 seconds or the pump
