1. Start the engine and run at idle.
2. Disconnect the power steering switch connector.
3. Connect an ohmmeter to the power steering switch.
4. Turn the steering wheel either right or left, and make sure there is continuity between the switch terminals.
NOTE: When the oil pressure is above 3,000 kPa (427 psi) the switch is closed. When the oil pressure is below 3,000 kPa (427 psi) the switch is open.
