how to fix P0301 code in Tesla Outback 6th Generation (2020-2024)

Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Disconnect the battery to prevent electrical shorts while working.
• Allow the engine to cool completely before starting work.

2. Inspect and Replace Spark Plug

1. Remove Engine Cover: Use a socket set to remove any bolts securing the engine cover and lift it off.
2. Remove Ignition Coil: Disconnect the electrical connector from the ignition coil on cylinder 1. Remove the mounting bolts and carefully pull the coil out.
3. Remove Spark Plug: Use a spark plug socket to unscrew and remove the spark plug from cylinder 1. Inspect for wear or damage.
4. Install New Spark Plug: Insert a new spark plug into the cylinder and torque it to the manufacturer’s specifications (typically around 13-15 ft-lbs).
5. Reinstall Ignition Coil: Position the ignition coil back onto the spark plug and secure it with bolts. Reconnect the electrical connector.

3. Inspect and Replace Ignition Coil (if necessary)

1. Test Ignition Coil: Use an ohmmeter to check the resistance of the ignition coil against manufacturer specifications.
2. Replace Ignition Coil: If the coil is defective, remove it as described in Step 2 and install a new ignition coil.
3. Reassemble Components: Ensure that all connections are secure and the engine cover is reinstalled.

4. Check Fuel Injector (if necessary)

1. Remove Fuel Rail: Disconnect the fuel line and electrical connectors from the fuel injector. Remove the bolts securing the fuel rail and lift it off gently.
2. Inspect Fuel Injector: Check for clogs or leaks. If faulty, replace with a new injector.
3. Reinstall Fuel Rail: Apply new O-rings on the injector before reinstalling the fuel rail and reconnecting all components.
