Power Steering Pressure Switch: Testing and Inspection
Testing Power Steering Pressure Switch
1. Disconnect P/S pressure switch connector.
2. Start engine and check for switch continuity with an ohmmeter. While turning the steering wheel, the switch should show continuity. With the
steering wheel in the straight ahead position (not being turned), there should be no continuity between switch terminals.
3. Reconnect switch connector after checking.
Power steering switch input can be checked at ECU terminal 1P. At idle, terminal voltage should be approximately 0V with the switch "ON" and
approximately 12V with the switch "OFF."
