This article applies to the Ford F-150 (2004-2014) and F-250, F-350 Super Duty (2005-2014).

A TPS is the throttle position sensor that gives information to the computer of your F-150 or Super Duty on the position of a car's throttle. Your TPS is responsible for checking your engine to ensure fuel efficiency. If you notice your engine light is on, there are difficulties when you change gears, the gas level drops when the tank is full, your car automatically jerks when driving, the engine suddenly stalls, or you feel a surge in speed when on the highway, these are all signs that your TPS needs to be replaced.

Materials

  • Paper towel
  • Flat head screw driver
  • Carb cleaner
  • New throttle position sensor

Step 1 - Remove the obstacles

Remove the throttle body cover, then remove throttle body sensor, which is mounted on the front of your mantle fold. Then, take the accelerator cable off using a flat head screw driver by pressing under the part.

Make sure to remove the TPS sensor and 2 screws that connect to bottom of throttle body. Once the old sensor is off, replace it with the new one. Clean the throttle body really well, then install it back by reversing the steps above.

Pro Tip

  • When taking off the accelerator cable with the screw driver, remove it softly to avoid breaking the clips.
  • As a fourth step, you may want to clean the electric part of the valve with carb cleaner.
  • Remember to clear the memory of your codes after replacing the TPS.
