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

Solution

1. Preparation

• Gather tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Spark Plug

• Remove the ignition coil from cylinder 1:
  • Unplug the electrical connector.
  • Remove the bolts securing the ignition coil.
• Extract the spark plug using a spark plug socket.
• Inspect the spark plug for wear or carbon fouling.
• Replace the spark plug if necessary:
  • Use the manufacturer's recommended spark plug type.
  • Torque the new spark plug to the manufacturer’s specifications (typically around 13-15 lb-ft).
• Reinstall the ignition coil and reconnect the electrical connector.

3. Inspect and Replace Ignition Coil

• If the spark plug is in good condition, test the ignition coil:
  • Use a multimeter to measure the resistance according to manufacturer specifications.
• If the ignition coil is faulty, replace it:
  • Install the new ignition coil in reverse order of removal and ensure it is secured properly.

4. Inspect and Clean Fuel Injector

• Remove the fuel injector from cylinder 1:
  • Disconnect the electrical connector.
  • Remove any retaining clips or bolts.
• Inspect the injector for blockages or leaks.
• Clean the fuel injector using an appropriate fuel injector cleaner or replace it if necessary.
• Reinstall the injector, ensuring a proper seal.

5. Compression Test

• If misfire persists, perform a compression test:
  • Remove all spark plugs.
  • Insert the compression gauge into the cylinder 1 spark plug hole.
  • Crank the engine and record the compression reading.
• Compare the reading to manufacturer specifications. If it is below specifications, further engine diagnosis may be required.
