how to troubleshoot P0301 code on my Tesla Outback 6th Generation (2020-2024)?

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the negative battery terminal to prevent electrical shocks.

2. Replace Spark Plug and Ignition Coil

• Tools Required: Socket set, torque wrench, spark plug socket, dielectric grease.
• Remove the engine cover if necessary.
• Disconnect the electrical connector from the ignition coil for cylinder 1.
• Unbolt the ignition coil and remove it from the spark plug.
• Remove the spark plug using the spark plug socket and inspect it for wear.
• Install the new spark plug, ensuring to torque it to the manufacturer’s specifications (typically around 13-15 lb-ft).
• Apply dielectric grease to the ignition coil boot and re-install the ignition coil, securing it with bolts.

3. Check and Replace Fuel Injector (if necessary)

• Tools Required: Fuel injector puller, socket set, safety gloves.
• Disconnect the electrical connector from the fuel injector for cylinder 1.
• Relieve fuel pressure by removing the fuel pump fuse and starting the engine until it stalls.
• Remove the intake manifold if necessary to access the fuel injector.
• Remove the fuel injector retaining clips and pull the injector out gently.
• Inspect the old injector for clogs or damage, and replace it with a new one if necessary.
• Reinstall the fuel injector and reconnect the electrical connector.

4. Perform Compression Test

• Tools Required: Compression gauge.
• Remove the spark plug from cylinder 1 and install the compression gauge.
• Crank the engine for a few seconds and record the compression reading.
• Compare it against manufacturer specifications (usually between 140-200 psi).
• If the reading is low, further diagnostics may be required for internal engine issues.
