Chrysler Stratus Convertible. Manual — part 19

OPERATION

At above idle conditions, air flow through the

throttle body is controlled by a cable operated throt-
tle blade. During closed throttle idle conditions, the
idle air control motor controls air flow. Refer to Idle
Air Control Motor in this section.

ing bolts. Tighten bolts to 28.25 N·m (250 in. lbs.).

(4) Install speed control cable (if equipped) and

throttle cable into throttle lever.

(5) Install cables into cable bracket.
(6) Install air inlet tube. Tighten clamps to 3

6.5

N·m (25

65 in. lbs.) torque.

(7) Install the negative battery cable.

DESCRIPTION AND OPERATION (Continued)

INSTALLATION

(1) The throttle shaft end of the throttle body

slides into a socket in the TPS (Fig. 23). The socket
has two tabs inside it. The throttle shaft rests
against the tabs. When indexed correctly, the TPS
can rotate a few degrees to line up the mounting
screw holes with the screw holes in the throttle body.
The TPS has slight tension when rotated into posi-
tion. If it is difficult to rotate the TPS into position,
reinstall the sensor with the throttle shaft on the
other side of the tabs in the socket of the TPS.
Tighten mounting screws to 6.2 N·m (55 in. lbs.)
torque.

(2) After installing the TPS, the throttle plate

should be closed. If the throttle plate is open, install
the sensor on the other side of the tabs in the socket.

(3) Attach electrical connectors to idle air control

motor and throttle position sensor.

(4) Install throttle body to intake manifold. Refer

to throttle body in this section.

(5) Install the negative battery cable.

IDLE AIR CONTROL MOTOR—2.0/2.4/2.5L

The idle air control motor attaches to the side of

the throttle body (Fig. 24) or (Fig. 25) or (Fig. 26).

REMOVAL

(1) Remove throttle body. Refer to Throttle Body in

this section.

(2) Disconnect electrical connector from idle air

control motor and throttle position sensor.

(3) Remove idle air control motor mounting screws.
(4) Remove idle air control motor. Ensure O-ring is

removed with the motor.

INSTALLATION

(1) The new idle air control motor has a new

O-ring installed on it. If pintle measures more than 1
inch (25 mm) it must be retracted. Use the DRB AIS
Motor Open/Close Test to retract the pintle (battery
must be connected.)

(2) Carefully place idle air control motor into

throttle body.

REMOVAL AND INSTALLATION (Continued)

(3) Install mounting screws. Tighten screws to:

2.0L = 5.3 N·m (45 in. lbs.) 2.4/2.5L = 6.2 N·m (55 in.
lbs.) torque.

(4) Attach electrical connectors to idle air control

motor and throttle position sensor.

(5) Install throttle body. Refer to Throttle Body in

this section.

INTAKE AIR TEMPERATURE SENSOR—2.5L

The intake air temperature sensor threads into the

intake manifold plenum (Fig. 27).

REMOVAL

(1) Remove the negative battery cable.
(2) Disconnect electrical connector from sensor.
(3) Remove sensor.

INSTALLATION

(1) Install sensor. Tighten sensor to 12

6 1 N·m

(9

6 1 ft. lbs.) torque.

(2) Attach electrical connector to sensor.
(3) Install the negative battery cable.

MANIFOLD ABSOLUTE PRESSURE (MAP)
SENSOR

The MAP sensor attaches to the intake manifold

plenum (Fig. 27).

REMOVAL

(1) Remove the negative battery cable.
(2) Disconnect electrical connector from MAP sensor.
(3) Remove sensor mounting screws.
(4) Remove sensor.

INSTALLATION

(1) Insert sensor into intake manifold while mak-

ing sure not to damage O-ring seal.

(2) Tighten mounting screws to 3.4 N·m (30 in. lbs)

torque.

(3) Attach electrical connector to sensor.
(4) Install the negative battery cable.

POWERTRAIN CONTROL MODULE

The PCM engine control strategy prevents reduced

idle speeds until after the engine operates for 320 km
(200 miles). If the PCM is replaced after 320 km (200
miles) of usage, update the mileage and vehicle iden-
tification number (VIN) in the new PCM. Use the
DRB scan tool to change the millage and VIN in the
PCM. If this step is not done a Diagnostic Trouble
Code (DTC) may be set. Refer to the appropriate
Powertrain Diagnostic Manual and the DRB scan
tool.

The PCM attaches to a bracket between the air

cleaner housing and Power Distribution Center
(PDC).

REMOVAL

(1) Disconnect

negative

cable

from

auxiliary

jumper terminal (Fig. 28).

(2) Disconnect both 40-way connectors from PCM.
(3) Remove screws attaching PCM to bracket (Fig.

29).

(4) Lift PCM up to remove it from vehicle.

INSTALLATION

(1) Install PCM. Tighten mounting screws.
(2) Attach both 40-way connectors to PCM.

OXYGEN SENSOR 1/1 UPSTREAM—2.5L

REMOVAL

(1) Remove the negative battery cable.
(2) Raise and support vehicle.
(3) Disconnect electrical connector from sensor.

(4) Remove sensor using an oxygen sensor crow

foot wrench such as Snap-On tool YA8875 or equiva-
lent (Fig. 30).

INSTALLATION

(1) After removing the sensor, the exhaust mani-

fold threads must be cleaned with an 18 mm X 1.5 +
6E tap. If reusing the original sensor, coat the sensor
threads with an anti-seize compound such as Loctite

t

771-64 or equivalent. New sensors have compound on
the threads and do not require an additional coating.
Tighten the sensor to 28 N·m (20 ft. lbs.) torque.

(2) Connect electrical connector to sensor.
(3) Lower vehicle.
(4) Install the negative battery cable.

(2) Raise vehicle.
(3) Disconnect electrical connector from sensor.
(4) Disconnect sensor electrical harness from clips

along body.

(5) Remove sensor using an oxygen sensor crow

foot wrench such as Snap-On tool YA8875 or equiva-
lent (Fig. 31).

INSTALLATION

(1) After removing the sensor, the exhaust mani-

fold threads must be cleaned with an 18 mm X 1.5 +
