(4) Remove TPS from throttle body.
INSTALLATION
The throttle shaft end of throttle body slides into a
socket in TPS (Fig. 24). The TPS must be installed so
that it can be rotated a few degrees. If sensor will
not rotate, install sensor with throttle shaft on other
side of socket tangs. The TPS will be under slight
tension when rotated.
(1) Install TPS and two retaining bolts.
(2) Tighten bolts to 7 N·m (60 in. lbs.) torque.
(3) Manually operate throttle control lever by hand
to check for any binding of TPS.
(4) Connect TPS electrical connector to TPS.
(5) Install air duct/air box to throttle body.
IDLE AIR CONTROL (IAC) MOTOR—3.9/5.2/
5.9L ENGINES
The IAC motor is located on the back of the throt-
tle body (Fig. 25).
REMOVAL
(1) Remove air duct at throttle body.
(2) Disconnect electrical connector from IAC motor.
(3) Remove two mounting bolts (screws) (Fig. 25).
(4) Remove IAC motor from throttle body.
INSTALLATION
(1) Install IAC motor to throttle body.
