Description & Operation: Notes

Electronic Power Steering (EPS) system uses the same components as that conventional steering system. In addition, it has a angular velocity sensor located in steering column, a solenoid valve on power steering gear box, and a control unit on left rear side of trunk.

To control oil flow of steering gear box, a solenoid is provided and it functions by current from control module which receives signal from VSS, TPS, and regular velocity sensor. EPS performs conventional power steering function in case a fail has occurred in the system. EPS electronically controls current to solenoid of by-pass valve by input sensor's signal to control the hydraulic amount in cylinder chamber thereby varying steering effort versus hydraulic pressure according to vehicle speed. See Figure . The Electronic Power Steering Control Module (EPSCM) is installed on left side of trunk. See Figure .
