Power Steering Pressure Switch: Testing and Inspection
Power Steering Pressure Switch Testing
1.
Disconnect P/S pressure switch connector.
2.
Start engine and check switch continuity. 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.
3.
If not as specified, replace switch.
Power steering switch input can be checked at ECU. At idle, terminal voltage should be below 1.0V with the switch "ON" and approximately 12V with
the switch "OFF."
