INSTALLATION

INSTALLATION - 2.7L
(1) Install throttle body and bolts.
(2) Tighten bolts to 11.9 N·m (105 in. lbs.) torque.
(3) Install the throttle body support bracket to the
bottom of the throttle body. Tighten the bolts to 27.1
N·m (20 ft. lbs.) torque.
(4) Hold throttle lever in wide open throttle posi-
tion. Install throttle cable and speed control cable.
(5) Install throttle cable bracket and tighten bolts.
(6) Install air plenum and tighten clamp.
(7) Connect negative cable to battery.

INSTALLATION - 3.5L

(1) Hold throttle lever in wide open throttle posi-
tion. Install throttle cable and speed control cable.
(2) Install throttle body and bolts.
(3) Tighten bolts to 11.9 N·m (105 in. lbs.) torque.
(4) Install the throttle body support bracket to the
bottom of the throttle body. Tighten the bolts to 27.1
N·m (20 ft. lbs.) torque.
(5) Install vacuum hose.
(6) Install throttle cable bracket and tighten bolts.
(7) Install air plenum and tighten clamp.
(8) Install cowl plenum.
(9) Install cowl screen.
(10) Install wiper arms.
(11) Connect negative cable to battery.

THROTTLE CONTROL CABLE

REMOVAL

(1) Working from the engine compartment, hold
the throttle body throttle lever in the wide open posi-
tion. Pull the cable forward and slide it out of the
throttle body cam.
(2) From inside the vehicle, hold up the pedal and
remove the cable retainer and throttle cable from the
upper end of the pedal shaft (Fig. 1).
(3) Remove retainer clip from throttle cable and
grommet at dash panel (Fig. 2).
(4) From the engine compartment, pull the throttle
cable out of the dash panel grommet. The grommet
should remain in the dash panel.
(5) Remove the throttle cable from throttle bracket
by carefully compressing both retaining ears simulta-
neously. Then gently pull the throttle cable from
throttle bracket.
INSTALLATION
(1) From the engine compartment, push the hous-
ing end fitting into the dash panel grommet.
(2) Install the cable housing (throttle body end)
into the cable mounting bracket on the engine.
(3) From inside the vehicle, hold up the pedal and
install throttle cable and cable retainer in the upper
end of the pedal shaft (Fig. 1).
(4) At the dash panel, install the cable retainer
clip between the end of the throttle cable fitting and
grommet (Fig. 2).
(5) From the engine compartment, rotate the
throttle lever to wide open and install the throttle
cable.
THROTTLE POSITION SENSOR
DESCRIPTION
The throttle position sensor mounts to the side of
the throttle body (Fig. 27) or (Fig. 28).The sensor
connects to the throttle blade shaft. The TPS is a
variable resistor that provides the Powertrain Con-
trol Module (PCM) with an input signal (voltage).

2 - THROTTLE BODY

OPERATION

The signal represents throttle blade position. As
the position of the throttle blade changes, the resis-
tance of the TPS changes.
The PCM supplies approximately 5 volts to the
TPS. The TPS output voltage (input signal to the
powertrain control module) represents throttle blade
position. The TPS output voltage to the PCM varies
from approximately 0.6 volt at minimum throttle
opening (idle) to a maximum of 4.5 volts at wide open
throttle.
Along with inputs from other sensors, the PCM
uses the TPS input to determine current engine oper-
