Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and powered down.
Disconnect the 12V battery for safety before working on electrical components.

2. Update Software

Turn on the vehicle and navigate to the software settings.
Check for any available updates and install them.
Restart the vehicle post-update to ensure changes take effect.

3. Inspect Throttle Position Sensor

Locate the throttle position sensor (TPS) near the accelerator pedal.
Disconnect the electrical connector and inspect for any damage or corrosion.
Use a multimeter to test the TPS for proper voltage output according to specifications.
- Expected Voltage: Typically around 0.5V to 4.5V depending on pedal position.
If faulty, replace the TPS.

4. Check Motor and Battery Connections

Open the front trunk and locate the battery and motor connections.
Inspect all terminals for tightness and signs of corrosion.
Clean any corroded terminals with a wire brush and apply dielectric grease to prevent future corrosion.
Reconnect all terminals securely.

5. Reconnect Battery

Reconnect the 12V battery.
Ensure all connections are tight and secure.
Start the vehicle and allow it to recalibrate the throttle system.
