THROTTLE POSITION SENSOR (TPS)
The throttle position sensor attaches to the side of
the throttle body (Fig. 93).
REMOVAL
(1) Disconnect EVAP purge hose from throttle
body.
(2) Disconnect electrical connector from idle air
control motor and throttle position sensor.
(3) Remove throttle body. Refer to Throttle Body in
this section.

INSTALLATION
(1) The throttle shaft end of the throttle body
slides into a socket in the TPS (Fig. 94). 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.
(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 nip-
ple.
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.

(2) Remove throttle body. Refer to Throttle Body in
this section.
(3) Remove electrical connector from idle air con-
trol motor and throttle position sensor.
(4) Remove the EVAP purge hose from the throttle
body.
(5) Remove idle air control motor mounting screws
(Fig. 95).
(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) Connect electrical connector to idle air control
motor and throttle position sensor.
