what does P0302 code mean for my Tesla Outback 6th Generation (2020-2024)

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Disconnect the negative battery terminal to prevent electrical shorts.
• Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, compressed air (optional).

2. Inspect and Replace Spark Plug

• Remove the engine cover if applicable.
• Locate and remove the spark plug for Cylinder 2 using a socket wrench.
• Inspect the spark plug for wear or fouling; replace it if necessary.
• Torque the new spark plug to manufacturer specifications, usually around 13-15 lb-ft.

3. Check Ignition Coil

• Disconnect the ignition coil connector for Cylinder 2.
• Remove the ignition coil using a socket wrench.
• Test the ignition coil using a multimeter. If it shows resistance outside of manufacturer specifications, replace it.
• Reinstall the new or functioning ignition coil and reconnect the connector.

4. Inspect Fuel Injector

• Disconnect the fuel injector harness for Cylinder 2.
• Remove the fuel rail if necessary to access the injector.
• Test the fuel injector for proper operation (using a noid light or multimeter).
• If faulty, replace the fuel injector. Reinstall the fuel rail and reconnect all connectors.

5. Verify Compression

• If misfire persists, perform a compression test on Cylinder 2.
• Remove the spark plug and insert a compression gauge.
• Crank the engine and record the reading. Compare it to manufacturer specifications.
• If the compression is low, further investigation into internal engine components may be required.
