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

Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the battery to prevent electrical hazards.

2. Replace Spark Plug

• Sub-steps:
  1. Remove the engine cover if applicable.
  2. Disconnect the ignition coil connector from cylinder 1.
  3. Remove the ignition coil by unscrewing the retaining bolt.
  4. Unscrew the spark plug using a spark plug socket.
  5. Install the new spark plug, tightening to the manufacturer's specified torque (typically 13-15 lb-ft).
  6. Reinstall the ignition coil and reconnect the electrical connector.

3. Test Ignition Coil

• Sub-steps:
  1. Swap the ignition coil from cylinder 1 with one from another cylinder.
  2. Clear the codes using the OBD-II scanner.
  3. Start the engine and see if the misfire follows the coil to the new cylinder.
  4. If the misfire moves, replace the ignition coil with a new one.

4. Inspect and Clean Fuel Injector

• Sub-steps:
  1. Remove the fuel rail according to the manufacturer’s service manual.
  2. Carefully remove the fuel injector from cylinder 1.
  3. Clean the injector using a fuel injector cleaning kit or replace it if necessary.
  4. Reinstall the injector and fuel rail, ensuring proper sealing.

5. Perform Compression Test

• Sub-steps:
  1. Remove the spark plug from cylinder 1.
  2. Insert a compression gauge into the spark plug hole.
  3. Crank the engine and record the compression reading.
  4. Compare the reading to specifications (typically around 150-200 psi).
  5. If compression is low, further investigation is needed for potential internal engine issues.
