how to fix P0302 code on Tesla Outback 5th Generation (2015-2019)

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative terminal of the battery to ensure safety.
• Allow the engine to cool down before beginning work.

2. Replace Spark Plug

• Tools Required: Socket set, torque wrench, spark plug socket.
• Remove the ignition coil from cylinder 2 by unscrewing the retaining bolts.
• Carefully pull the ignition coil out to access the spark plug.
• Use a spark plug socket to remove the old spark plug.
• Inspect the removed spark plug for signs of wear (e.g., carbon buildup, damage).
• Install the new spark plug and torque to the manufacturer’s specification (typically around 13 lb-ft).
• Reattach the ignition coil and secure it with bolts.

3. Inspect/Replace Ignition Coil

• If the spark plug is in good condition, check the ignition coil.
• Tools Required: Multimeter (for testing).
• Remove the ignition coil and test for proper resistance using a multimeter.
• If the coil is faulty, replace it with a new one.
• Reinstall the ignition coil ensuring it is seated properly.

4. Test Fuel Injector

• Tools Required: Fuel injector cleaning kit (if necessary).
• Remove the fuel injector from cylinder 2.
• Check for clogs or defects in the injector.
• Use a cleaning kit to clean the injector if it appears dirty.
• If the injector is defective, replace it.

5. Compression Test

• Tools Required: Compression tester.
• Remove the spark plug for cylinder 2 and insert the compression tester.
• Crank the engine and record the compression reading.
• Compare the reading to the manufacturer’s specifications (should be within range).
• If compression is low, further investigation into engine internals may be necessary.
