Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, throttle body cleaner, screwdriver set.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Clean 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 thoroughly.
Ensure the throttle plate opens and closes smoothly without obstruction.
Reattach the air intake duct securely.

3. Inspect Accelerator Pedal Position Sensor

Locate and remove the accelerator pedal assembly using the socket set.
Disconnect the electrical connector from the accelerator pedal position sensor.
Use a multimeter to check the resistance across the sensor terminals. Replace if readings are outside specifications.

4. Check Fuel Delivery System

Inspect the fuel pump and fuel filter for any signs of damage or clogging.
If necessary, replace the fuel filter according to the manufacturer's guidelines.
Test fuel pressure using a fuel pressure gauge; ensure it meets the specifications for the vehicle.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the engine and check for proper operation when the gas pedal is pressed.
If the issue persists, further diagnostics may be required for electronic control systems.
