Power Steering Pressure Switch
- Disconnect power steering pressure switch connector, located on power steering pump. Using a DVOM, check for continuity between switch and chassis ground. Continuity should not exist with wheels in straight-ahead position and engine idling. Continuity should exist when wheels are turned.
- Using a DVOM, with ignition switch in ON position, check for battery voltage at sensor connector terminal. If battery voltage exists, circuit is okay. If battery voltage does not exist, check and repair circuit between switch connector and ECM connector terminal No. 2 (16-pin connector).
