REMOVAL AND INSTALLATION (Continued)
(2) Disconnect electrical connector from idle air
control motor and throttle position sensor.
(3) Remove throttle body. Refer to Throttle Body in
this section.
(4) Remove throttle position sensor mounting screws.
(5) Remove throttle position sensor.
INSTALLATION
(1) The throttle shaft end of the throttle body slides
into a socket in the TPS (Fig. 93). The socket has two
tabs inside it. The throttle shaft rests against the
tabs. When indexed correctly, the TPS can rotate
clockwise 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 position. If it
is difficult to rotate the TPS into position, install the
sensor with the throttle shaft on the other side of the
tabs in the socket. Tighten mounting screws to 2 N·m
(17 in. lbs.) torque.
Fig. 93 Throttle Position Sensor Installation
(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) Install throttle body. Refer to Throttle Body in
this section.
(4) Attach electrical connectors to idle air control
motor and throttle position sensor.
(5) Install EVAP purge hose to throttle body nipple.
IDLE AIR CONTROL MOTOR
When servicing throttle body components, always
reassemble components with new O-rings and seals
where applicable. Never use lubricants on O-rings or
seals, damage may result. If assembly of component is
difficult, use water to aid assembly. Use care when
removing hoses to prevent damage to hose or hose
nipple.
REMOVAL
(1) Disconnect negative cable from battery.
(2) Remove electrical connector from idle air con-
trol motor and throttle position sensor.
(3) Remove the EVAP purge hose from the throttle
body.
(4) Remove throttle body. Refer to Throttle Body in
this section.
(5) Remove idle air control motor mounting screws
(Fig. 94).
Fig. 94 Servicing Idle Air Control Motor
(6) Remove motor from throttle body. Ensure the
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 Idle
Air Control Motor Open/Close Test to retract the
pintle (battery must be connected.)
(2) Carefully place idle air control motor into
throttle body.
(3) Install mounting screws. Tighten screws to 2
N·m (17 in. lbs.) torque.
(4) Install throttle body. Refer to Throttle Body in
this section.
(5) Connect electrical connector to idle air control
motor and throttle position sensor.
(6) Connect the EVAP purge hose to the throttle
body nipple.
(7) Connect negative cable to battery.
MAP/IAT SENSOR—SOHC
The MAP/IAT sensor attaches to the intake mani-
fold plenum (Fig. 95).
REMOVAL
(1) Disconnect the electrical connector from the
MAP/IAT sensor.
(2) Remove sensor mounting screws.
(3) Remove sensor.
