how to resolve P0302 misfire code on Tesla Outback 4th Generation (2010-2014)

Solution

1. Preparation

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

2. Inspect and Replace Spark Plug

• Tools Required: Socket set, spark plug socket, torque wrench
• Remove the engine cover (if applicable).
• Locate the spark plug for cylinder 2.
• Using a spark plug socket, remove the spark plug.
• Inspect the spark plug for wear; replace if necessary.
• Install the new spark plug and torque it to the manufacturer’s specification (typically around 13-15 lb-ft).

3. Inspect and Replace Ignition Coil

• Tools Required: Socket set, multimeter (for testing)
• Disconnect the electrical connector from the ignition coil for cylinder 2.
• Remove the ignition coil from the cylinder head.
• Test the ignition coil with a multimeter for proper resistance (check manufacturer specifications).
• If faulty, replace the ignition coil with a new one.
• Reinstall the ignition coil and reconnect the electrical connector.

4. Inspect and Test Fuel Injector

• Tools Required: Fuel pressure gauge, multimeter
• Disconnect the fuel injector connector for cylinder 2.
• Test the fuel injector using a multimeter to ensure it has proper resistance.
• If the injector is faulty, replace it with a new one.
• Reconnect the fuel injector connector.

5. Perform Compression Test (if necessary)

• Tools Required: Compression tester
• Remove the spark plug from cylinder 2.
• Insert the compression tester into the spark plug hole.
• Crank the engine and check the compression reading.
• Compare the reading to manufacturer specifications; if low, further investigation for internal engine issues may be needed.
