why does my Tesla Outback 5th Generation (2015-2019) keep stalling while driving?

Solution

1. Preparation

• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the battery to ensure safety while working on electrical components.

2. Address Check Engine Codes

• Connect the OBD-II scanner and retrieve any stored error codes.
• Research codes to determine potential issues (e.g., P0300 for misfires).
• Clear codes after addressing the identified issues.

3. Inspect and Replace Battery Connections

• Remove the negative battery terminal using a socket wrench.
• Clean any corrosion from battery terminals using a wire brush.
• Reconnect the terminal securely and ensure proper tightness.

4. Test and Replace Fuel Pump

• Locate the fuel pump access panel (if applicable) or remove the fuel tank for access.
• Use a multimeter to check the fuel pump voltage.
• If necessary, replace the fuel pump with a new unit.
• Reassemble any removed components and reconnect the fuel lines.

5. Examine and Replace Ignition Components

• Remove the ignition coils and spark plugs using a socket set.
• Inspect the spark plugs for wear or damage; replace if necessary.
• Test ignition coils with a multimeter; replace any faulty coils.
• Reinstall the components ensuring proper torque specifications are used.

6. Clean or Replace Air Intake Components

• Detach the air intake duct and inspect for blockages.
• Clean the mass airflow sensor with appropriate cleaner (do not use regular cleaners).
• Replace any damaged air filters.

7. Throttle Position Sensor Check

• Locate the throttle position sensor.
• Use a multimeter to check the sensor voltage and resistance.
• Replace the sensor if readings are outside the manufacturer specifications.
