How to Replace Throttle Position Sensor TPS 98-12 Ford Ranger

Difficulty: Beginner · About 20 min · Ford Ranger

Change the throttle position sensor on a Ford Ranger by disconnecting its plug, swapping the two fasteners, and checking engine response.

Steps

1. Disconnect the sensor

   Switch the ignition off and release the electrical connector from the throttle position sensor. Check the plug for corrosion or damaged wiring before proceeding.

2. Remove the old sensor

   Remove the two retaining screws and lift the sensor away from the throttle body. Keep dirt from entering the exposed opening.

3. Install and reconnect

   Position the replacement sensor in the same orientation and tighten its screws evenly. Reconnect the wiring plug until the lock clicks into place.

4. Check operation

   Start the engine and confirm it idles smoothly and responds normally to gentle throttle input. If a warning light remains, scan for codes and verify the part and adjustment.

Check your vehicle’s repair manual for exact specifications and fit.
