Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the vehicle battery to prevent electrical shorts.
  • Allow the engine to cool before starting work.
2. Cleaning the Throttle Body
  • Remove the air intake duct connected to the throttle body.
  • Use throttle body cleaner and a soft cloth to clean the throttle body and the butterfly valve.
  • Ensure that the valve operates smoothly without sticking.
  • Reattach the air intake duct securely.
3. Inspecting and Replacing the Throttle Position Sensor
  • Locate the throttle position sensor on the throttle body.
  • Disconnect the electrical connector and remove the screws holding the TPS.
  • Install the new throttle position sensor, ensuring it is properly aligned.
  • Reconnect the electrical connector securely.
4. Fuel System Check
  • Connect a fuel pressure gauge to the fuel rail.
  • Turn the ignition to the ON position (do not start) to check the fuel pressure.
  • If pressure is below specifications, inspect and replace the fuel pump or filter as needed.
  • Reconnect all components after checking.
5. Final Assembly and Battery Connection
  • Reattach any components or covers removed during inspection and repairs.
  • Reconnect the vehicle battery.
  • Start the engine and allow it to idle to check for any leaks or irregularities.
