what causes my Tesla Model S Original (2012-2020) to stall when accelerating

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is in a safe working environment.
• Disconnect the high-voltage battery pack according to Tesla's safety procedures.

2. Check and Update Software

• Connect the vehicle to Wi-Fi or a mobile hotspot.
• Navigate to the software update settings and check for available updates.
• If an update is available, follow the prompts to install the update.

3. Inspect Battery Connections

• Carefully remove the battery cover using a socket set.
• Check all battery terminal connections for tightness and corrosion.
• Clean any corroded terminals with a wire brush and apply dielectric grease.
• Reinstall the battery cover securely.

4. Test Accelerator Pedal Position Sensor

• Use a multimeter to test the resistance across the accelerator pedal position sensor.
• Compare readings to the specifications in the service manual.
• If readings are out of spec, replace the accelerator pedal assembly.

5. Inspect and Test Electric Motor

• Visually inspect the electric motor for any signs of damage or wear.
• If necessary, use a multimeter to test motor windings for continuity.
• If issues are detected, the motor may need to be replaced by a qualified technician.
