INSTALLATION

3.5L

(1) The throttle shaft end of the throttle body

slides into a socket in the TPS. 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 posi-
tion. 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 5.1 N·m (45 in. lbs.) torque.

(2) After installing the TPS (2), 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) Attach electrical connector to the TPS (2) (Fig.

87).

(4) Connect the negative battery cable.
