how to fix P0301 misfire code in Tesla Outback 5th Generation (2015-2019)

Solution

1. Preparation

• Gather tools and parts needed for repair.
• Disconnect the battery to ensure safety while working on electrical components.

2. Replace Spark Plug

• Remove the engine cover (if applicable) using a socket set.
• Identify the spark plug in cylinder 1.
• Use a spark plug socket to remove the old spark plug.
• Check the gap on the new spark plug using a feeler gauge and adjust as necessary.
• Install the new spark plug to the manufacturer’s torque specification (typically 15 lb-ft).
• Reattach the engine cover.

3. Inspect and Replace Ignition Coil (if necessary)

• Locate the ignition coil for cylinder 1.
• Disconnect the ignition coil connector.
• Remove the ignition coil using a socket set.
• If the coil is faulty, install a new ignition coil and reconnect the connector.

4. Clean or Replace Fuel Injector (if necessary)

• Disconnect the fuel injector connector.
• Remove the fuel injector from the rail (may require fuel line removal).
• Inspect the injector for clogs; clean using an ultrasonic cleaner or replace if necessary.
• Reinstall the fuel injector ensuring proper seating and reconnect the connector.

5. Compression Test (if necessary)

• Remove the spark plug from cylinder 1 again.
• Insert a compression tester into the spark plug hole.
• Crank the engine and note the compression reading. Compare it to manufacturer specifications (typically 120-200 psi).
• If compression is low, further investigation may be required (e.g., checking piston rings or valves).
