(2) Install and tighten two mounting bolts (screws)
to 7 N·m (60 in. lbs.) torque.
(3) Install electrical connector.
(4) Install air duct at throttle body.
IDLE AIR CONTROL (IAC) MOTOR—4.7L V–8
ENGINE
The IAC motor is located on the throttle body.
REMOVAL
(1) Remove air duct and air resonator box at throt-
tle body.
(2) Disconnect electrical connector from IAC motor
(Fig. 20).
(3) Remove two mounting bolts (screws) (Fig. 21).
(4) Remove IAC motor from throttle body.
INSTALLATION
(1) Install IAC motor to throttle body.
(2) Install and tighten two mounting bolts (screws)
to 7 N·m (60 in. lbs.) torque.
(3) Install electrical connector.
(4) Install air duct/air box to throttle body.
MANIFOLD ABSOLUTE PRESSURE (MAP)
SENSOR—3.9/5.2/5.9L ENGINES
The MAP sensor is located on the front of the
throttle body (Fig. 26). An L-shaped rubber fitting is
used to connect the MAP sensor to throttle body (Fig.
27).
REMOVAL
(1) Remove air duct at throttle body.
(2) Remove two MAP sensor mounting bolts
(screws) (Fig. 26).
(3) While removing MAP sensor, slide the vacuum
rubber L-shaped fitting (Fig. 27) from the throttle
body.
(4) Remove rubber L-shaped fitting from MAP sen-
sor.
INSTALLATION
(1) Install rubber L-shaped fitting to MAP sensor.
