I I I Steering gear I
1 2 1 Additional cooling loop I
Independent of the equipment level, all vehicles
have conventional power-assisted rack and pinion
steering with an additional cooling loop.
The steering gear is supplied with hydraulic fluid
by a hydraulic pump.
The hydraulic pump is driven by the accessory
drive belt and has a separate reservoir.
Vehicles with petrol engines have a Power Steering
Pressure (PSP) switch in the pressure line, which
opens as the power steering load increases, thus
signalling to the Powertrain Control Module (PCM)
that it should increase the idle speed.

Principles of Operation
The steering wheel rotational movement is
transferred to the steering gear through the steering
column shaft. The steering gear converts this
rotational movement, through the action of the rack
and pinion gear into lateral movement. This
movement in turn is transferred to the wheel
knuckles through the tie-rods and tie-rod ends.
Hydraulic fluid under pressure is supplied to the
steering gear by the power steering pump. As the
steering wheel is rotated, the hydraulic fluid is
allowed to pass through the steering gear valve to
one side of a double acting piston, dependent on
which direction the steering wheel is rotated. The
fluid moves the piston, which forms part of the
steering gear, giving power assistance to the effort
required to rotate the steering wheel.
Vehicles with petrol engines, due to the extra load
on the engine imposed by the power steering
pump, have a power steering pressure (PSP)
switch. The switch, which is normally closed, sends a signal
to the powertrain control module (PCM)
during low speed parking manoeuvres. The PCM
responds by maintaining the engine idle speed.
lnspection and Verification
1. Verify the customer concern.
2. Visually inspect for obvious signs of mechanical
or electrical damage.
