ENGINE SPEED SENSING POWER STEERING
Fluid Pressure Inspection
1. Assemble the SSTs as shown in the figure.
2. Disconnect the pressure pipe from the oil pump,
and connect the SSTs.
Tightening torque
29.4—44.1 N·m {3.0—4.4 kgf·m, 22—32 ft·lbf}
3. Bleed the air from the system.
4. Open the gauge valve fully.
5. Start the engine and turn the steering wheel fully
left and right to raise the fluid temperature to 50—
60 °C {122—140 °F}.
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
excessively and adversely affect the oil
pump.
