Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, cleaning supplies.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery to prevent electrical shorts during repair.

2. Inspect and Clean Throttle Body

Remove the air intake duct connected to the throttle body.
Use a throttle body cleaner and a soft cloth to gently clean the inside of the throttle body.
Ensure no debris enters the intake manifold during cleaning.
Reattach the air intake duct securely.

3. Replace Throttle Position Sensor (if faulty)

Locate the throttle position sensor connected to the throttle body.
Disconnect the electrical connector from the sensor.
Remove the mounting screws using a socket set.
Install the new throttle position sensor by reversing the removal steps.
Reconnect the electrical connector securely.

4. Reconnect Battery and Perform Throttle Calibration

Reconnect the battery terminals, ensuring a tight fit.
Start the vehicle and let it idle for a few minutes.
Perform a throttle calibration procedure (consult the owner's manual for specific steps for the Tesla system).
Test the throttle response by driving at varying speeds.
