Power Steering Pressure Switch: Description and Operation
Power Steering Pressure Switch
The Power Steering Pressure Switch (PSPS) closes during high pressure power steering load situations. When the power steering switch is closed, the
A/C relay is turned "OFF", disengaging the compressor clutch. A signal is also sent to the ECM. The ECM uses this signal for idle speed control.
