Power Steering Pressure Sensor

Power Steering Pressure (PSP) sensor monitors power steering pressure. PSP sensor voltage input to PCM will change as hydraulic pressure changes. PCM uses PSP sensor input signal to compensate for additional loads on engine by adjusting idle speed RPM, and prevents engine stall during parking maneuvers. PCM also uses PSP signal to adjust transaxle/transmission Electronic Pressure Control (EPC) pressure during increased engine load.
