Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is on a level surface and engage the parking brake.
  • Disconnect the battery to prevent electrical shorts.
2. Clean the Throttle Body
  • Remove the air intake duct to access the throttle body.
  • Use throttle body cleaner and a soft brush to clean the throttle plate and surrounding area.
  • Reinstall the air intake duct securely.
3. Inspect and Replace the Accelerator Pedal Position Sensor
  • Locate the accelerator pedal position sensor (usually mounted on the pedal assembly).
  • Disconnect the electrical connector and remove the sensor using a socket set.
  • Install the new sensor, ensuring it is properly aligned and secured.
  • Reconnect the electrical connector.
4. Check and Replace Transmission Fluid
