how to fix P0302 code in Tesla Outback 4th Generation (2010-2014)

Solution

1. Preparation

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

2. Inspect and Replace Spark Plug

• Tools Required: Socket set, torque wrench, spark plug socket.
• Remove the ignition coil from cylinder 2 by unscrewing the mounting bolts.
• Carefully pull out the spark plug using a spark plug socket.
• Inspect the spark plug for signs of wear, carbon buildup, or damage.
• If necessary, replace the spark plug with a new one, ensuring it is gapped correctly.
• Reinstall the ignition coil and secure it with the mounting bolts.

3. Check and Replace Ignition Coil

• If the spark plug is in good condition, test the ignition coil using an ohmmeter.
• If the coil is faulty, remove it from cylinder 2.
• Install a new ignition coil, ensuring it is seated properly and secured with bolts.

4. Inspect and Clean Fuel Injector

• Remove the fuel injector from cylinder 2 by disconnecting the electrical connector and unscrewing it from the fuel rail.
• Inspect the injector for clogs or damage.
• Clean the injector using a fuel injector cleaner or replace it if necessary.
• Reinstall the fuel injector ensuring it seals correctly against the fuel rail.

5. Compression Test

• If misfire persists, perform a compression test on cylinder 2.
• If compression is low, diagnose for potential internal engine issues such as valve problems or head gasket failure.
