Power Steering Pressure Switch: Description and Operation
Power Steering Pressure Switch
Wiring Diagram
The power steering pressure switch is located under the engine on the rack and pinion housing under the ABS hydraulic unit. When a load is placed on
the power steering, such as a full lock, the switch opens. The PCM uses the switch status to extend the idle speed control motor during high power
steering pressure loads to help maintain a stable idle. Code E040 sets when vehicle speed is above 45 m.p.h. and the switch is open.
