How to Install TPS on a 1990 Ford F 350 5 8L

The 1990 Ford F-350 truck was available with three engines: a 5.8L Windsor engine, a 7.3L engine, a 7.5L engine, and a 4.9L engine. The 5.8L engine, like the others, comes with a throttle position sensor, also called a TPS. The throttle position sensor helps to regulate the trucks idle. If its faulty, the idle may be high, low, or otherwise irregular. Removing the old TPS and installing a new one shouldnt take you longer than 15 minutes.

Instructions

1

Turn off the F-350s engine. Gather your tools and replacement throttle position sensor.

2

Open the F-350s hood to view the 5.8L engine. Move to the passenger side of the engine compartment. Look in the center, behind the intake manifold, right next to the area the large black air hose comes from. Youll see the throttle position sensor mounted next to the air hose. The sensor looks similar to a capital "T." The top part of it is wide. The bottom part (the connector) is thin. It is a black plastic piece.

3

Push the tab on the TPS electrical connection and unplug it from the sensor. The connection is attached to the thin part of the throttle position sensor.

4

Remove the two screws with a Phillips screwdriver. Carefully pull the TPS away from its mount.

5

Insert and seat the new throttle position sensor in its mount. Insert and tighten the two screws. Plug in the electrical connection. Shut the hood.
