Power Steering Pressure Switch

  1. Disconnect pressure hose from power steering pump. See Fig 1 . Install adapter on power steering pump. Install adapter on disconnected hose. Connect pressure gauge and shutoff valve between adapters. Open shutoff valve. Bleed steering hydraulic system. See HYDRAULIC SYSTEM BLEEDING in appropriate POWER STEERING article in STEERING.
  2. Install a thermometer in fluid reservoir. Start engine and allow it to idle. Turn steering wheel several times until fluid temperature reaches 122-140°F (50-60°C). Disconnect PSP switch connector. Install a DVOM between ground and PSP switch terminal. See Fig 1 . Note continuity reading on DVOM. Go to next step.
  3. With engine idling, gradually close shutoff valve to increase power steering system pressure. Check pressure when PSP switch is activated by watching for a change in continuity. Pressure should be 261-348 psi. Gradually open shutoff valve to decrease pressure. Check pressure when PSP switch is de-activated. Pressure should be 116-203 psi. Turn engine off. If PSP switch does not respond as specified, replace switch.
