Power Steering Pressure Switch: Testing and Inspection
Power Steering Oil Pressure Switch Location
To test the Power Steering Switch remove the connector and test the terminal for ground with a continuity tester (ohmmeter). With the engine running
and the power steering under a load (steering wheel being turned from stop to stop) there should be a ground, with no load (steering wheel centered and
stationary) there should be no ground.
