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

Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Ensure the vehicle is on a level surface and set the parking brake.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Ignition Components

• Sub-steps:
  1. Remove the engine cover if applicable to access the ignition components.
  2. Disconnect the electrical connector from the ignition coil of cylinder 2.
  3. Remove the ignition coil using a socket set (usually 10mm).
  4. Inspect the spark plug in cylinder 2 for wear; if it appears worn or fouled, replace it.
  5. Install a new spark plug with the recommended torque (typically 15-20 ft-lbs).
  6. Reinstall the ignition coil and reconnect the electrical connector.

3. Check Fuel Injector Functionality

• Sub-steps:
  1. Locate the fuel injector connector for cylinder 2.
  2. Disconnect the fuel injector connector.
  3. Use a multimeter to check the resistance of the fuel injector (should be within manufacturer specifications).
  4. If out of spec, replace the fuel injector.
  5. Reconnect the fuel injector connector after replacement.

4. Perform Compression Test

• Sub-steps:
  1. Remove the spark plug from cylinder 2.
  2. Insert a compression gauge into the spark plug hole.
  3. Crank the engine for a few seconds and record the compression reading.
  4. If the compression is low, further investigation into valve or piston issues is needed.
