Removal & Installation



3.5L Engines
  1. Before servicing the vehicle, refer to the Precautions section.

  3. Disconnect the negative battery cable.
  4.  
  5. Disconnect the TPS electrical connector.
  6.  
  7. Remove the TPS mounting screws and remove the TPS.

To install:


NOTE
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 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.

  1. Tighten TPS sensor mounting screws to 5.1 Nm (45 inch lbs.) torque.
  2.  
  3. 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.
  4.  
  5. Attach electrical connector to the TPS sensor.
  6.  
  7. Connect the negative battery cable.
