Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Inspect Throttle Body

Remove the air intake duct connected to the throttle body.
Clean the throttle body using throttle body cleaner and a soft cloth.
Reinstall the air intake duct securely.

3. Check Accelerator Pedal Position Sensor

Locate the accelerator pedal assembly and disconnect the electrical connector.
Use a multimeter to test the sensor's resistance across the terminals as per the service manual specifications.
Replace the sensor if it does not meet specifications.

4. Inspect Fuel System

Connect a fuel pressure gauge to the fuel rail.
Start the engine and observe the fuel pressure reading; it should meet manufacturer specifications.
If pressure is low, check the fuel pump and filter for issues and replace as necessary.

5. Clear Error Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any fault codes that may have been stored.
