Power Steering Pressure Switch: Testing and Inspection
On-Vehicle Inspection
IDLE UP SYSTEM CHECK
1. Warm up engine to normal operating temperature.
2. Turn A/C switch OFF, if equipped.
3. Turn steering wheel fully and check idle speed. Engine idle speed drops a little momentarily when steering wheel is turned fully but returns to its
specified level immediately. If power steering pressure switch connector is connected, check the same with that connector disconnected.
Momentary drop of engine idle speed should be less when it is connected than when disconnected.
