Solution
1. Preparation
  • Gather all necessary tools and parts before starting the repair.
  • Disconnect the negative battery terminal to prevent electrical shocks.
  • Ensure the engine is cool before beginning work on the throttle body.
2. Clean Throttle Body
  • Tools Required: Throttle body cleaner, soft cloth, screwdriver set, socket set.
  • Remove the air intake duct connected to the throttle body using the appropriate screwdriver or socket.
  • Use throttle body cleaner to spray the inside of the throttle body.
  • Gently scrub the throttle body with a soft cloth to remove carbon deposits.
  • Allow it to dry completely before reassembling.
3. Inspect and Test Accelerator Pedal Position Sensor
  • Tools Required: Multimeter.
  • Locate the accelerator pedal position sensor and disconnect its electrical connector.
  • Using a multimeter, measure the voltage output of the sensor at rest and during full throttle application.
  • If the readings are outside the specified range, replace the sensor.
4. Check Fuel System Pressure
  • Tools Required: Fuel pressure gauge.
  • Locate the fuel rail and connect the fuel pressure gauge.
  • Turn the ignition to the 'ON' position (do not start the engine) to check the fuel pressure.
  • Verify that the pressure matches the manufacturer's specifications. If it is low, inspect the fuel pump and filter.
5. Reassemble and Reconnect Battery
  • Reattach the air intake duct to the throttle body.
  • Ensure all connectors are properly secured.
  • Reconnect the negative battery terminal and start the engine to check for proper operation.
