Power Steering (P/S) Pressure Switch (Sidekick)

Disconnect wire connector from P/S pressure switch on P/S pump. Start engine. Connect ohmmeter between ground and switch terminal. With steering wheel in the straight ahead position, there should be no continuity.
Turn steering wheel. As steering pressure increases, there should be continuity. If there is no continuity when steering wheel is turned or if there is continuity with steering wheel in the straight ahead position, replace P/S switch.
