Symptom Troubleshooting
Hard Steering
NOTE:
• Compare to a known-good vehicle that is the same
trim level.
• Check for suspension damage.
• Check the steering alignment.
• Check the tire condition and pressure.
1. Check the power assist (see page 17-9).
Is the initial turning load more than 29 N ( 3.0 kgf ,
6.6 lbf ) ?
−
YES Go to step 2.
NO − Power assist is OK at this time. Compare to a
known-good vehicle.
2. Connect the P/S joint adapter (pump), P/S joint
adapter (hose), and P/S pressure gauge T/N 07406-
0010001 (see page 17-11), T/N 07406-001000A or
T/N 07406-001A101 (see page 17-12) to the pump.
3. Measure steady-state fluid pressure from the pump
at idle.
Is the pressure 1,47 0 kPa ( 15 kgf / cm , 213 psi) or
less?
YES − Go to step 4.
−
NO Go to step 8.
4. Measure the pump relief pressure at idle.
Is the pressure 8,140 8,830 kPa ( 83 90 kgf / cm ,
1,180 1,280 psi) or more? −
−
YES Go to step 5.
NO − Go to step 9.

5. Using a spring scale, measure the power assist in
both directions, to the left and to the right.
Are the two measurements within 5.0 N ( 0.51 kgf ,
1.12 lbf ) of each other?
YES − Go to step 6.
−
NO Go to step 11.
6. Measure the fluid pressure with both pressure
gauge valves open (if so equipped), while turning
the steering wheel fully to the left and fully to the
right.
Is the pressure 8,140 8,830 kPa ( 83 90 kgf / cm , −
1,180 1,280 psi) or more in both directions? −
YES − Go to step 7.
−
NO Faulty steering gearbox. Replace the steering
gearbox.
7. Adjust the rack guide (see page 17-35), and retest.
Is the steering OK ?
−
YES Repair is completed.
NO − Faulty steering gearbox. Replace the steering
gearbox.
8. Check the outlet and return hoses and lines
between the pump and the steering gearbox for
clogging and deformation.
Are the lines clogged or def ormed?
−
YES Replace the lines.
NO − Faulty valve body unit. Replace the valve
body.
