Power Steering

DESCRIPTION
The electronic variable orifice (EVO) system is designed to vary flow from the power steering pump as a function of vehicle speed and steering wheel rate of rotation, giving a form of variable assist. The system provides:
^ full power steering assist at low vehicle speed for light parking effort.
^ minimum assist at high speed for good road feel and directional stability.
^ full assist during evasive maneuvers.

The EVO electrical circuit is combined in the air suspension control module.

SYSTEM COMPONENTS
^ EVO power steering control valve actuator is attached to the CIII power steering pump.
^ Shock absorber electronic steering sensor is attached to lower steering column.
^ Vehicle speed sensor (VSS) is attached to transmission.
^ Test connector is located in luggage compartment behind RH side quarter-panel carpet.
^ Control module is located between the dash panel and instrument panel on the air conditioning plenum on the passenger side behind the glove compartment.
