Solution

1. Preparation

Gather tools and parts needed for the task.
Required tools: OBD-II scanner, multimeter, basic socket set.
Ensure the vehicle is parked on a flat surface and the engine is off.

2. Disconnect the Battery

Open the hood and locate the battery.
Using a socket wrench, remove the negative (-) terminal first, followed by the positive (+) terminal.
Ensure that the battery is completely disconnected by checking that no electrical components are functioning.

3. Reset the Throttle Position Sensor

With the battery disconnected, wait for at least 15 minutes to allow all systems to reset.
Reconnect the battery, starting with the positive (+) terminal and then the negative (-) terminal.
Tighten the terminals securely to prevent any loose connections.

4. Relearn the Throttle Position

Start the engine and let it idle without pressing the accelerator for at least 10 minutes.
After 10 minutes, turn off the engine and wait for 30 seconds.
Restart the engine and check if the idle is stable.

5. Verify Throttle Position Sensor Functionality

Use the OBD-II scanner to check for any error codes.
If there are no error codes and the engine runs smoothly, the reset is complete.
