Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the ignition is off.
Gather tools and parts as needed.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Diagnose Throttle Response

Reconnect the battery and power on the vehicle.
Access the throttle response settings in the vehicle’s software interface.
If settings are off, recalibrate them according to manufacturer specifications.
Use the OBD-II scanner to clear any stored fault codes and reset the system.

3. Check Accelerator Pedal Position Sensor

Locate the accelerator pedal assembly.
Disconnect the electrical connector from the accelerator pedal position sensor.
Use a multimeter to measure the resistance; ensure it meets the manufacturer's specifications.
If the readings are out of spec, replace the accelerator pedal position sensor.

4. Inspect Electric Motor and Inverter

Remove the cover to access the electric motor and inverter.
Check for signs of overheating, such as discoloration or burnt components.
If damage is found, replace the affected components as necessary.
Ensure all connections are secure and free from corrosion.

5. Reassemble and Test

Reconnect any connectors you may have unplugged during inspection.
Replace any covers removed during the repair.
Reconnect the battery and power on the vehicle to check if the issue persists.
