Throttle Position Sensor: Installation

The throttle position sensor attaches to the side of the throttle body.

1. The throttle shaft end of the throttle body slides into a socket in the TPS. Note to make sure that the rubber o-ring is in place and seated around the TPS rotor housing surface. 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, reinstall the sensor with the throttle shaft on the other side of the tabs in the socket of the TPS. Tighten mounting screws to 6.2 N.m (55 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. Attach electrical connectors to the throttle position sensor.
4. Install the negative battery cable.
5. Install the air cleaner lid and makeup air hose and tighten clamp.
