how to fix a sticky throttle in my Ford F-150 Fourteenth Generation (2021-present)

Solution

1. Preparation

• Gather all necessary tools and parts.
• Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Clean Throttle Body

• Remove the air intake duct by loosening the clamps and detaching it from the throttle body.
• Use throttle body cleaner and a soft cloth or brush to clean the inside of the throttle body, removing any carbon buildup.
• Ensure that the throttle plate moves freely after cleaning.

3. Check Throttle Cable and Pedal Assembly

• Inspect the throttle cable for fraying or kinks; replace if necessary.
• Check the accelerator pedal for smooth operation; lubricate pivot points if required.
• If the cable is not adjustable, ensure it is routed correctly without any obstructions.

4. Test and Replace Throttle Position Sensor (if necessary)

• Using a multimeter, test the TPS by probing the voltage output while slowly pressing the accelerator pedal.
• If readings are outside the specified range (0.5V to 4.5V), replace the TPS.
• To replace, disconnect the electrical connector, remove mounting screws, and install a new sensor, ensuring proper alignment.

5. Reassemble and Final Checks

• Reattach the air intake duct, ensuring all clamps are tight.
• Reconnect the battery.
• Clear any diagnostic codes if present using the OBD-II scanner.
