Chrysler Crossfire. Manual — part 695

5. Install the throttle body inlet tube (1) by installing

the upper air cleaner housing and tubes (2), then
install the inlet tube to the throttle body by pushing
the throttle body inlet tube in firmly on the throttle
body, ensuring the inlet tube lever (3) is attached.

6. Connect the negative battery cable.

THROTTLE POSITION SENSOR

DESCRIPTION

The Throttle Position Sensor (TPS) is a part of the Throttle Body.

The TPS cannot be serviced separately. Refer to the Throttle Body removal and installation procedures. (Refer to 14
- FUEL SYSTEM/FUEL INJECTION/THROTTLE BODY - REMOVAL).

OPERATION

The Throttle Position Sensor (TPS) contains two actual value potentiometers for detecting the position of the throttle
valve. The second potentiometer is designed to form a reference value. The system will switch over to the second
potentiometer if the first one fails. The TPS cannot be serviced separately. If the TPS fails, the Throttle Body must
be replaced. Refer to the Throttle Body service procedures. (Refer to 14 - FUEL SYSTEM/FUEL INJECTION/
THROTTLE BODY - REMOVAL).

STEERING

DESCRIPTION

STEERING SYSTEM

The Power Steering Pump is a constant flow rate and displacement vane type pump. The Pump Reservoir is
attached to the pump body. The pump is connected to the steering by the pressure and return hoses. The Steering
Gear used is a recirculating ball type gear. A column provides steering input.

The Power Steering System consists of the following components:

•

Steering Gear

•

Power Steering Pump

•

Reservoir

•

Pressure Hose

•

Return Hose

OPERATION

The Steering Gear rack piston balls act as a rolling thread between the worm shaft and rack piston. The worm shaft
is supported by a thrust bearing at the lower end and a bearing assembly at the upper end. When the worm shaft
is turned from the Steering Column the rack piston moves. The rack piston teeth mesh with the pitman shaft. Turn-
ing the worm shaft turns the pitman shaft, which moves the steering linkage.

DIAGNOSIS AND TESTING

POWER STEERING SYSTEM

There is some noise in all Power Steering Systems. One of the most common is a hissing sound evident at a
stand-still or at park with the engine running. Or when the steering wheel is at the end of its travel. Hiss is a high
frequency noise similar to that of a water tap being closed slowly. The noise is present in all valves that have a high
velocity fluid passing through an orifice. There is no relationship between this noise and steering performance.
