how to fix the P0301 code in my Tesla Outback 5th Generation (2015-2019)

Solution

1. Preparation

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

2. Inspect and Replace Spark Plug

• Remove the ignition coil from cylinder 1:
  • Use a socket wrench to remove the bolts securing the ignition coil.
  • Gently pull the ignition coil out.
• Remove the spark plug:
  • Use a spark plug socket to unscrew and remove the spark plug.
• Inspect the spark plug for wear or damage; replace it if necessary with the correct part number.
• Gap the new spark plug according to manufacturer specifications and install it.

3. Inspect and Replace Ignition Coil

• If the spark plug is in good condition, visually inspect the ignition coil for cracks or corrosion.
• If replacement is needed, install a new ignition coil:
  • Align the ignition coil with the spark plug and press it down into place.
  • Secure it with the bolts previously removed.
• Reconnect the electrical connector to the ignition coil.

4. Fuel Injector Check

• If misfire persists, check the fuel injector for cylinder 1:
  • Remove the fuel rail according to the service manual, ensuring to relieve fuel pressure beforehand.
  • Test the fuel injector with a multimeter for continuity.
  • Clean or replace the fuel injector as necessary.

5. Compression Test

• If misfire continues, perform a compression test on cylinder 1:
  • Remove the spark plug and install the compression tester.
  • Crank the engine and note the compression reading.
  • If the reading is low, further investigation into valve or piston issues may be required.

Tools Required:

• OBD-II scanner
• Socket set
• Torque wrench
• Compression tester
• Multimeter
• Spark plug socket
• Fuel injector cleaning kit (if applicable)

Parts Required:

• Spark plug (correct part number)
• Ignition coil (if necessary)
• Fuel injector (if necessary)

Estimated Repair Time: 2-4 hours

Safety Warnings:

• Disconnect the battery before working on electrical systems.
• Allow the engine to cool before opening any components.
