Power Steering Switch

  1. Start engine and run at idling speed. Disconnect power steering switch connector.
  2. Connect a volt/ohmmeter to the power steering switch. Turn steering wheel either right or left, and make sure there is continuity between switch terminals.
  3. When oil pressure is above 427 psi (30.0 kg/cm2 ), power steering switch should be closed. When oil is below 427 psi (30.0 kg/cm2 ), power steering switch should be open.
