Remove the floor cover to access the accelerator pedal assembly.
Disconnect the electrical connector from the accelerator pedal position sensor.
Use a multimeter to test the sensor’s voltage according to the service manual specifications.
If faulty, replace the accelerator pedal position sensor.

4. Throttle Body Inspection

Disconnect the battery negative terminal to ensure safety.
Remove the air intake duct to access the throttle body.
Inspect the throttle body for carbon buildup or obstructions.
Clean the throttle body using throttle body cleaner and a soft brush if necessary.
Reassemble the intake duct and reconnect the battery.

5. Battery Health Check

Use a multimeter to check the voltage of the high-voltage battery.
If the battery voltage is below the manufacturer’s recommended level, consider replacing the battery or servicing it.
