ENGINE SPEED SENSING POWER STEERING
6. Open the gauge valve fully and increase the
engine speed to 1,000— 1,500 rpm.
7. Turn the steering wheel fully to the left and right,
then measure the fluid pressure generated at the
gear housing. If the pressure is not within the
specification, repair or replace the steering gear
component.
Gear housing fluid pressure
FS engine: 7.9— 8.3 MPa
{80— 85 kgf/cm2, 1138— 1208 psi}
KL engine: 8.4— 8.8 MPa
{85— 90 kgf/cm2, 1209— 1279 psi}
8. Remove the gauge set. Install and tighten the
pressure pipe to the specified torque.
Tightening torque
24— 29 N m {2.4— 3.0 kg fm , 18— 21 ft lbf}
9. Bleed the air from the system. (Refer to 06-12
AIR BLEEDING.)
STEERING WHEEL AND COLUMN INSPECTION
Steering Wheel Play Inspection
1. With the wheels in the straight-ahead position,
gently turn the steering wheel to the left and right
and verify that the play is within the specification.
Play
0— 30 mm {0— 1.18 in}
2. If the play exceeds the specification, either the
steering joints are worn or the backlash of the
steering gear is excessive. Correct as necessary.
Steering Wheel Looseness Inspection
• Move the steering wheel as shown in the figure to
inspect for column bearing wear, steering shaft
joint play, steering wheel looseness, and column
looseness.

Steering Wheel Effort Inspection
1. Inspect the following points:
(1) Tire size and tire pressure
(2) Fluid level
(3) Drive belt deflection
2. With the vehicle on a hard, level surface, put the
wheels in the straight-ahead position.
3. Start the engine and warm the power steering fluid
to 50—60 °C {122— 140 °F}.
