Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic socket set, and screwdrivers.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Update Software

Connect the vehicle to a Wi-Fi network.
Navigate to the software update section in the vehicle’s settings.
Download and install any available updates, following on-screen instructions.

3. Inspect and Replace Throttle Position Sensor

Disconnect the vehicle's battery to prevent electrical shorts.
Locate the throttle position sensor (usually near the throttle body).
Remove any covers or components obstructing access to the sensor.
Disconnect the electrical connector from the throttle position sensor.
Remove the screws securing the sensor and carefully take it out.
Install the new throttle position sensor by reversing the removal steps.
Reconnect the electrical connector and any covers removed.

4. Test Accelerator Pedal Assembly

Reconnect the vehicle's battery.
Use a multimeter to test the resistance across the accelerator pedal assembly.
If the readings are outside the manufacturer’s specifications, replace the accelerator pedal assembly.

5. Clear Error Codes

Use the OBD-II scanner to clear any fault codes that may have been logged.
Perform a system reset to reinitialize vehicle parameters.
