how to fix P0302 misfire code in Tesla Outback 6th Generation (2020-2024)

Solution

1. Preparation

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

2. Inspect and Replace Spark Plug

• Remove the ignition coil cover to access the spark plugs.
• Use a spark plug socket to remove the spark plug from cylinder 2.
• Inspect the spark plug for wear or carbon buildup; replace if necessary.
• Torque the new spark plug to the manufacturer's specification (typically around 13-15 lb-ft).
• Reinstall the ignition coil and cover.

3. Inspect and Replace Ignition Coil

• If the spark plug is in good condition, remove the ignition coil from cylinder 2.
• Test the ignition coil with a multimeter to ensure it is functioning correctly (primary and secondary resistance).
• Replace the ignition coil if it is defective.
• Reinstall the ignition coil ensuring it is seated properly.

4. Test Fuel Injector

• Connect a fuel injector tester to cylinder 2's fuel injector.
• Activate the tester to check for proper spray pattern and operation.
• Replace the fuel injector if it is clogged or malfunctioning.
• Reinstall the fuel injector ensuring it is secure.

5. Compression Test

• Remove the spark plug from cylinder 2 and install a compression gauge.
• Crank the engine and record the compression reading; it should meet manufacturer's specifications (generally around 150-200 psi).
• If compression is low, further investigation is needed into the engine's internal components.
