why does my Tesla Model S Plaid/Refresh (2021-present) have a delayed shift when accelerating

Solution

1. Preparation

• Ensure the vehicle is parked on a level surface and turned off.
• Gather necessary tools and equipment.

2. Update Software

• Connect the vehicle to Wi-Fi.
• Navigate to the software settings and check for any available updates.
• Follow on-screen prompts to initiate and complete the update process.

3. Inspect Drive Unit

• Access the drive unit information through the Tesla service menu.
• Look for any fault codes or warnings that indicate issues with the drive unit.
• If fault codes are present, document them for further analysis or repair.

4. Throttle Response Calibration

• Use Tesla’s diagnostic tools to access throttle response settings.
• Perform a calibration if necessary, following on-screen instructions.
• Confirm that the calibration is successful and that the throttle response is now accurate.

5. Accelerator Pedal Sensor Testing

• Disconnect the accelerator pedal sensor connector.
• Using a multimeter, check the resistance across the sensor terminals according to Tesla specifications.
• If the readings are outside the specified range, replace the accelerator pedal sensor.

6. Final Inspection

• Reconnect all components and ensure that all connections are secure.
• Perform a test drive to confirm that the delayed shift issue has been resolved.
