Solution

1. Preparation

Gather necessary tools and parts.
Tools Required: OBD-II scanner, socket set, battery terminal wrench.
Safety Warnings: Ensure the vehicle is in park (or neutral) and on a level surface; wear safety gloves and goggles.

2. Battery Disconnection

Locate the vehicle's battery, usually found in the trunk or under the hood.
Using a battery terminal wrench, disconnect the negative (-) terminal first, followed by the positive (+) terminal.
Wait for approximately 10 minutes to allow the ECU to reset.

3. Reconnect Battery

Reconnect the positive (+) terminal first, followed by the negative (-) terminal.
Ensure all connections are secure to prevent any electrical issues.

4. Throttle Body Calibration

Turn the ignition key to the "On" position (do not start the engine).
Use the OBD-II scanner to access the throttle adaptation option, if available.
Follow the prompts on the scanner to complete the throttle adaptation process, which may involve pressing the accelerator pedal to the floor and then releasing it.

5. Final Checks

Start the engine and allow it to idle without any load for a few minutes.
Monitor the engine's idle quality and responsiveness to throttle input.
