Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the vehicle's battery to ensure safety during repairs.
  • Allow the vehicle to cool if the engine has been running.
2. Check and Replace Throttle Body

  1. Remove the throttle body cover:

    • Use a socket set to remove any screws or bolts securing the cover.
    • Carefully lift the cover off without damaging any gaskets.

  2. Inspect the throttle body:

    • Clean the throttle body with throttle body cleaner and a soft cloth.
    • Check for any carbon buildup or obstructions.

  3. Test the throttle body sensor:

    • Use a multimeter to test continuity and resistance according to manufacturer specifications.
    • If faulty, replace the throttle body with a new one.

  4. Reinstall the throttle body:

    • Position the throttle body back in place and secure it with the bolts.
    • Ensure gaskets are seated properly to prevent air leaks.
3. Check Accelerator Pedal Position Sensor

  1. Locate the pedal position sensor:

    • Follow the accelerator pedal assembly to find the sensor attached.

  2. Test the sensor:

    • Disconnect the electrical connector and use a multimeter to check for voltage and ground.
    • Replace the sensor if readings are outside specification.

  3. Reattach the connector:

    • Ensure the connector is fully seated and secure.
4. Reconnect Battery
  • Reconnect the vehicle's battery terminals, ensuring they are tight and free of corrosion.
5. Clear Error Codes
  • Use the OBD-II scanner to clear any stored error codes after repairs are made.
