Solution
1. Preparation
  • Gather tools and parts needed for the repair.
  • Ensure the vehicle is parked on a level surface and the engine is turned off.
  • Disconnect the battery to ensure safety while working on electrical components.
2. Clean Throttle Body
  • Remove the air intake duct connected to the throttle body using a socket set.
  • Use throttle body cleaner and a soft brush to clean the throttle plate and surrounding areas.
  • Ensure no debris falls into the intake manifold during cleaning.
  • Reattach the air intake duct, ensuring all clamps are securely fastened.
3. Inspect and Test Sensors
  • Check the Accelerator Pedal Position Sensor (APPS):

    • Disconnect the electrical connector from the APPS.
    • Using a multimeter, measure the resistance across the terminals while pressing the pedal.
    • Compare readings with specifications; replace the sensor if out of range.
  • Check the Mass Air Flow Sensor (MAF):

    • Disconnect the MAF connector and remove the sensor from the air intake.
    • Clean the MAF sensor using MAF cleaner and reinstall it.
4. Fuel System Inspection
  • Check fuel pressure:
    • Attach a fuel pressure gauge to the fuel rail service port.
    • Start the engine and observe the pressure reading; it should match specifications.
    • If pressure is low, inspect the fuel pump and fuel filter for blockages.
5. Reconnect Battery and Test
  • Reconnect the battery terminals securely.
  • Clear any trouble codes from the ECM using the OBD-II scanner.
  • Start the engine and allow it to reach operating temperature.
