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

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Ensure the vehicle is parked on a level surface and turn off the ignition.
• Disconnect the negative battery terminal for safety.

2. Inspect and Replace Spark Plug

• Tools Required: Socket set, torque wrench, spark plug socket.
• Remove the ignition coil from cylinder 1:
  1. Unscrew the mounting bolts and gently lift the coil out.
  2. Inspect the coil for cracks or carbon tracking.
• Remove the spark plug using a spark plug socket:
  1. Clean the area around the spark plug to prevent debris from entering the cylinder.
  2. Carefully unscrew the spark plug and inspect it for signs of wear, fouling, or damage.
• If necessary, replace the spark plug with a new one, ensuring it is gapped to the manufacturer's specifications (typically around 0.028 to 0.032 inches).
• Reinstall the ignition coil, ensuring it is properly seated and secured.

3. Inspect and Replace Fuel Injector (if needed)

• Tools Required: Fuel injector puller, socket set, torque wrench.
• Disconnect the fuel injector connector and fuel line (be cautious of fuel spillage).
• Remove the fuel injector from cylinder 1:
  1. Use the fuel injector puller to remove it from the rail.
  2. Inspect the injector for clogs or damage.
• If replacement is required, install the new fuel injector and reconnect the fuel line and electrical connector.

4. Compression Test (if needed)

• Tools Required: Compression tester.
• Remove the spark plug from cylinder 1.
• Insert the compression tester into the spark plug hole and crank the engine to take a reading.
• Compare the compression reading with manufacturer specifications. If the reading is low, further investigation may be needed into the engine's internal components.
