Pump Pressure Test with T/N 07406-0010001
Special Tools Required
. P/S joint adapter (pump) 07'VAK-P8A011A
. P/S joint adapter plate (pump) 07ZAK-S7CA100
. P/S joint adapter (hose) 07ZAK-S7CA200
. P/S pressure gauge 07406-0010001
Check the fluid Dressure as follows to determine
whether the trouble is in the pump or gearbox.
1. Check the power steering fluid level
( s e e p a g e 1 7 - 1 2 ) .
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).

Connect the P/S joint adapter (hose) to the P/S
pressure gauge, then connect the pump outlet hose

6. Fully open the pressure control valve (B).
7. Start the engine and let it idle.
L Turn the steering wheelfrom lock-tolock several
times to warm the fluid to operating temperature at
1 5 8 " F ( 7 0 " ) .
9. Measure steady-state fluid pressure while the
engine is idling. lf the pump is in good condition,
the pressure should be no more than 1,500 kPa ( 15
kgf/cm'.214 psi). If the pressure is too high, check
the outlet hose or valve body unit (see Steering
System Troubleshooting) (see page 17-6).
Raise the engine speed to 3,000 rpm, and measure
the fluid pressure. lf the pump is in good condition,
the pressure should be al least 1,500 kPa (15
kgf/cm' ,214 psi). lfthe pressure istoo low, repair
or replace the pump.
10. Lowerthe engine speed and let it idle. Close the
shut-off valve, then close the pressure control valve
gradually untilthe pressure gauge needle is stable.
Read the oressure.
Do not keep the shut-off valve closed more
than 5 seconds or the pump could be
damaged by overheating.
1 1. lmmediately open the pressure control valve fully.
lf the pump is in good condition, the gauge should
read at least this specification:
K20A3 Engine model:
6,570 7,260 kPa {67 T4kgflcm',95O
1,0s0 psi)
K20A2 Engine model:
7,160 7,850 kPa {73 80 kgf/cm' , 1.040 1,140
psi)
A low reading means pump output is too low for
full assist. Repair or replace the pump.
