Power Steering (P/S) Pressure Switch
- 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 straight-ahead position, there should be no continuity.
- Turn steering wheel. As steering pressure increases, continuity should exist. If there is no continuity when steering wheel is turned or if there is continuity with steering wheel in straight-ahead position, replace P/S switch.
