Ford Escape: Power Steering / Description and Operation - Power Steering - Overview
Overview
The EPAS
system provides steering assist to the driver by replacing the
conventional, hydraulic pump system with an electric motor coupled to
the steering shaft. The system is controlled by the PSCM
which senses the steering effort using sensors mounted between the
steering column shaft and the steering gear. Steering assist is provided
in proportion to steering effort and vehicle speed.
