Power Steering Pressure Switch: Testing and Inspection

POWER STEERING PRESSURE SWITCH CHECK





1. Disconnect the pressure hose from the oil pump, and then connect the special tools.
2. Bleed the air, and then turn the steering wheel several times while the vehicle is not moving so that the temperature of the fluid rises to approximately 50 - 60°C (122 - 140°F).
3. The engine should be idling.
4. Disconnect the connector for the oil-pressure switch, and connect an ohmmeter.
5. Gradually close the shut-off valve of the pressure gage and increase the hydraulic pressure, and then check that the hydraulic pressure that activates the switch is at the standard value.
Standard value: 1.47 - 1.96 MPa (213 - 284 psi.)
6. Gradually open the shut-off valve and reduce the hydraulic pressure, and then check that the hydraulic pressure that deactivates the switch is at the standard value.
Standard value: 0.69 - 1.18 MPa (100 - 171 psi.)
7. Remove the special tools, and then tighten the pressure hose to the specified torque.
8. Bleed the system.
