ENGINE SPEED SENSING POWER STEERING
6. Close the gauge valve completely.
7. Increase the engine speed to 1,000—1,500 rpm
and measure the fluid pressure generated by the
oil pump.
• If the pressure is not within the specification,
repair or replace the oil pump component.
Caution
• • • • If the valve is left closed for more than 5
seconds, the fluid temperature will rise
ecessively and adversely affect the oil
pump.
Oil pump fluid pressure
10.80—11.29 MPa {110.2—115.2 kgf/cm
8. Open the gauge valve fully and increase the
engine speed to 1,000—1,500 rpm.
9. 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.
Caution
• • • • If the steering wheel is kept in the fully
turned position for more than 5 seconds,
the fluid temperature will rise ecessively
and adversely affect the oil pump.
Gear housing fluid pressure
10.80—11.29 MPa {110.2—115.2 kgf/cm
10. Remove the SSTs. Install and tighten the pressure pipe to the specified torque.
Tightening torque
29.4—44.1 N·m {3.0—4.4 kgf·m, 22—32 ft·lbf}
11. Bleed the air from the system.
