my Tesla Outback has a P0302 code, what does it mean?

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the battery to prevent electrical shock.

2. Inspect and Replace Spark Plug

• Tools Required: Socket set, torque wrench, spark plug socket.
• Remove the ignition coil from cylinder 2.
• Take out the spark plug using the spark plug socket.
• Inspect the spark plug for fouling or damage; replace if necessary.
• Install the new spark plug and torque it to the manufacturer's specifications (usually around 13-18 lb-ft).

3. Check and Replace Ignition Coil

• Tools Required: Socket set, torque wrench.
• Remove the ignition coil from cylinder 2.
• Test the ignition coil with a multimeter for resistance.
• If faulty, replace with a new ignition coil and secure it according to the manufacturer's torque specifications.

4. Inspect and Clean Fuel Injector

• Tools Required: Fuel injector cleaner kit, basic hand tools.
• Remove the fuel injector from cylinder 2.
• Clean the fuel injector using a professional cleaning kit or replace it if clogged.
• Reinstall the fuel injector and ensure proper seating.

5. Compression Test

• Tools Required: Compression tester.
• Insert the compression tester into the spark plug hole of cylinder 2.
• Crank the engine and record the reading.
• Compare the reading with the manufacturer’s specifications; if low, further investigation into internal engine issues may be required.
