Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Throttle Body Inspection

Remove the air intake duct to access the throttle body.
Inspect the throttle body for carbon buildup and clean it using throttle body cleaner.
Reinstall the air intake duct and reconnect any sensors or hoses.

3. Accelerator Pedal Position Sensor Check

Locate the accelerator pedal position sensor and disconnect the electrical connector.
Using a multimeter, measure the resistance across the sensor terminals while slowly pressing the accelerator pedal.
If the readings are inconsistent or out of spec, replace the accelerator pedal position sensor.

4. Electric Motor and Inverter Inspection

Check for any visible damage or loose connections in the motor and inverter.
If necessary, consult the service manual for testing procedures specific to the electric motor and inverter performance.

5. Transmission Fluid Check (if applicable)

Check the transmission fluid level using the dipstick (if equipped).
If low, add the appropriate transmission fluid and inspect for leaks.
If fluid is dirty, consider a transmission fluid change.
