Power Steering Switch: Description and Operation
Power Steering Pressure Switch
PURPOSE
The Engine Control Module (ECM) uses the signal to modify injector opening time to compensate for the extra load being placed on the engine at
idle.
OPERATION
When the steering wheel is moved at idle speed, the Power Steering switch senses the change in pressure and closes, sending a ground signal to the
fuel ECM. On receiving this signal, the ECM increases idle speed to compensate for the additional load from the power steering pump.
